Searching for New Pottery Glazes - Reduction Fired to 1290ºc
Vložit
- čas přidán 28. 05. 2024
- Finally, here's the video all about the recent glaze testing I've been doing. All of the tests in this video were made for reduction firing in a gas kiln, so please take that into account for the glazes that I do share the recipes for. I'm certainly no chemist and I wish my glaze knowledge was better but this film shows the process I took to find new glazes and how I experimented to find some exciting new surfaces. I can't wait to see how some of these will look on actual pots!
If you'd like to see the final selection of glazes straight away you can find them here, 25:37

Thank you so much for not gatekeeping your art and always being so transparent and inventive with your processes Florian
I’d like to suggest naming the first glaze “Heme,” or “Haem,” or “Haima.” I certainly don’t mean to be gory, but the glaze reminds me of blood, in the life-affirming and life-creating sense of that liquid. Hemes are components of hemoglobin, which gives blood its red pigment. Heme is American English. Haem is British English. And Haima is the Greek upon which the English words are based.
I’d also like to suggest “Rosetta” for the next-to-last, deep blackish color. It reminds me of the Rosetta Stone, rich, mysterious, and ultimately full of words that have borne extraordinary meaning.
Thank you for the video.
Glorious reply! I like those a lot. I'll add them to my list. Thanks very much for watching Kim, and for the suggestions too.
12:16 As a Dutch person, I can't help but be a little sad you're not very fond of the kobalt blue... The glazes you picked in the end are all lovely though.
It's just a little intense and doesn't fall into my colour palette, I've always been a sucker for neutral tones and it's just so vibrant! A lot like the Dutch, I'm probably the one missing out. Thank you very much for watching :)
As someone with archaeological training, seeing those “test tiles” makes me laugh thinking about how confused it would make future archaeologists if they found those during excavation. There’d be like a dozen papers and dissertations written on the possible meanings and uses of these “strange shaped ceramic artifacts”, LOL
"Probably ritual, probably sexual, definitely not gay"
They probably figured its a bunch of test tiles, after finding the other fully worked pottery around and given they all have different glazes
They will most likely make shit up like they do now.
Nah they would know. This process is what he said, very common. It’s also on the internet
sounds like your archeological training wasnt that good then
Imagine tiling a bathroom with all these different irregular tiny rectangles
all the random bits would look amazing as a kitchen counter backsplash or something.
The amount of information, insight and sheer fun watching your videos keeps amazing me.
Iam not even a potter but I just can not stop watching once the video started,
no matter how determined I was, just to take a peek or two, to see what you are up to.
Thank you Olaf, comments like that make my day. So happy to have you aboard and thanks for watching!
Oh my God it's exactly that!
'Ah maybe just a peek aaaaaaand I just watched the whole video.'
a little off topic but the tiny dinking noises as you move around the testers are so cute and satisfying :)
That dark blue with specles (with titanium dioxide) is gorgeous! It also seems to be brown-ish at the edges, so this is probably my favorite.
I don't know how glaze usually named, but that dark & gray one looks like a fog in the dark forest.
It looks just like Van Gogh's Starry Night I think but I'm glad you like it. I love what it does on the edges too, as it turns sort of metallic and shimmers.
@@floriangadsby I thought Starry Night the moment you showed the tile. It may be my favorite of the lot.
I think it's so incredibly generous that you share your glaze recipes - it's especially eye opening and useful as I'm dipping my toe into the bucket of glaze chemistry myself! One common theme I've heard from other potters is that they're rather protective of the glazes/clays they use as it's what prevents true copies from springing up - would love to know your thoughts on that!
Thank you for sharing this! I love seeing swatches in any form of art, whether it be ink, paint, or fiber dye. I especially love seeing the differences on the different clay bodies. It's just so satisfying to my magpie nature. I loved almost all of them; even the ones you didn't care for. The dark greens (CBB1 thru 3) and roasted pepper red (MK) are just *chef's kiss*.
That streaked black one is so cool looking! It looks like leather and I love it
Y4 on clay looks fantastic. On camera, anyway. Love the borders, love the spots, love the crackle, love the depth... Love how it complements the color of the clay below. Love how varied and yet cohesive it is across the tile. It's a shame you don't like browns. Not even sure I would call that brown, personally, as I see much more gray in it than red.
I was taken aback by the soapstone pebble glaze. Having never explored glazes it instantly appealed in the way a child finds a rock they like in a stream.
That soft brown glaze reminds me of one I use (nicknamed Ohio magic in my studio) comprised of 85 percent Cedar Heights Redart and 15 percent whiting. It is a soft satin brown with a greenish tinge where thick, and will be slightly more metallic and redder if mixed 90 to 10 instead of 85 to 15. It also never settles in the bucket.
by the way, I fire to 1280 degrees C and start reduction at about 700 degrees C.
I love the sound of a glaze that never settles in the bucket! I'll test that recipe when I next get around to firing, sounds interesting. Thanks for taking your time to watch! 🙌🏼
I really love the glaze at 23:06. When the light hits it just right it reminds me of my grandmother's pewter tableware, which I always loved.
It would be awesome to see a stoneware chess set with different glazes for the different sides. Maybe not just black and white, but something more interesting, with a Gadsby twist. A Florian Flourish, if you will.
I've never done pottery, yet I find this mesmerizing because you include all the info/experimentation. Really great video!
Thank you so much for the couple of recipes, your videos are always first rate, absolute class. Very much appreciated.
Can I ask what makes your crackle glazes food and dinnerware safe as all the crackle glazes I've seen say they aren't food safe. I love the look of crackle glazes and would love to put one on dinnerware if I could find a food safe one.
Hey! I’ve replied to this query already in the comments here somewhere but I’ll send it over again as it’s an interesting subject. Here's my usual copy and paste reply to that question. It's a big topic but I think there is quite a lot of misinformation that goes around surrounding it. Ultimately it comes down to a number of factors, but I'll put my longer response below. The linked article is well worth reading too! (Sorry for the wall of text that’s about to follow).
Well, there’s a lot to say. I’ve been using crackle glazed ceramics for years and years. I use high fired stoneware with nothing toxic in my functional wares glazes that could leech, the crackling doesn’t stain too badly as long as it’s properly washed but of course it happens overtime. To the same degree, many of the potters I’ve worked for over the years who wood fire, soda fire and so on, all have work that crazes and crackles to some degree and it all stains with time, yet functional work is still made abundantly and is it completely usable. There can be issues if you’re using toxic materials and if you use a clay body that’s fired to lower temperatures and isn’t fully vitrified you can end up with pots that leak when combined with crackle glazes.
I’ve never heard any stories of anyone getting ill from crackle glazed pottery, the clay is highly vitrified and unless you take terrible care of your ceramics you’ll be perfectly healthy. For industry it could be an issue, due to the surface of the pot having less strength, long-term staining with excessive use and fragility as it’s high fired stoneware with lots of iron, which makes it weaker and more susceptible to chipping on the whole, but that’s what you get with handmade ceramics, I don’t want to make pots that have perfect, uniform surfaces like you might find in a shop, I want each to be individual and interesting and handmade and I suppose the same goes for the generations of potters who’ve worked all over the world. Of course it depends on what materials you’re using in your glazes and/or if the you’re firing hot enough so that your clay is vitrified but if there’s nothing toxic and you’re firing very hot then there’s little that’ll hurt you.
Here’s a good link to an article that goes into more depth about it, ceramicartsnetwork.org/ceramics-monthly/ceramic-glaze-recipes/glaze-chemistry/techno-file-dirty-dishes/, and clears up some of the misconceptions that are spread around. As long as you properly wash crazed pottery there is no bacteria left in the crackles. As long as you take time to care for your handmade ceramics after they’ve been used then they’ll be just fine.
@@floriangadsby Thank you so much for the in depth explanation. It makes a lot of sense. Unfortunately the link isn't working.
Ah wonderful, I’ll update my copy/paste. Thanks for finding that, I spent ten minutes searching but to no avail.
@@floriangadsby amazing info!. I always tought about functional wares that have crackles on it. For example many asian pottery do have such as tea pots or yunomi.
@@floriangadsby I just watched another pottery video where they said that the cracks go through to the clay body, and the crazing makes your pottery weaker overtime. There was a video of a baking dish that had crazing in it and the butter was leaching through the piece!
I agree that it's not highly dangerous, and I love the beauty in something that most potters to be a flaw, but I would be worried about the longevity of the piece
i admire the details and attention you give to your work 😊😊
Thank you so much Steffie, appreciate you taking the time to watch.
Thank you for sharing your recipes. I'm going to try testing both the Thomastown Tenmoku and your own recipe tomorrow. I've been using this one for over 20 years at Sutton college and have found it really reliable. On a high iron clay you might find the red of the iron breaks through to the surface a bit too much unless the glaze is applied thickly.

Lovely to see the process behind the scenes. Amazing to see your test tiles and further testing. Can't wait to see some pieces glazed
I know you said blue was "trendy" right now, but I feel like blue on clay is a very classic thing. But at the same time, if it doesn't speak to you, then it doesn't speak to you. That being said, this was fascinating! This is only the second video of yours that I've watched, but I really enjoy the information you've shared.
Fascinating. It must be incredibly difficult reaching decisions about glaze properties; weighing those that speak to one's artistic instincts and pitting them against what is already known to have commercial appeal.
This was awesome. I did the same looking for the perfect mint green celadon and super light aqua celadon. Sadly haven’t been in my studio in 2 years with the 🦠going around. I’m a hairdresser with some older clients so I limit my exposure to everyone. The studio is in a teaching facility. Lots and lots of students. Love watching your videos. Thank you
I’m so excited about this video. I always wanted to see this process.
That was great. Thank you Florian.
Cheers Mark!
I kind of love these test tiles as objects. and when they are all arrayed together they look really cool.
I love that dusty green (the left tile using chrome oxide)! It's fascinating how everyone has widely different color preferences
This is so freaking cool. I love seeing the whole array of glazed test pieces.
Thank you for sharing your knowledge as always.
I love this video! The whole exploration aspect of it is so fun, and there are so many really cool results. If you decide to do this again, it would be lovely to watch the process again!
All of those glaze colors ( minus the toxic ones) look fantastic and deserve their spots inside a refrence notebook for future use. They all look gemstone esque in their hues, color, shade, and have a vivacity and personality any rock hound would love.
What a great video for anyone thinking of creating their own glazes. Time and numbers along with careful study and precision should be your guide. As always thank you.
I agree with the final choices. I was literally salivating watching those tiles test. I'm about to test a lot of glazes soon and you gave me motivation to do it ! Can't wait to see your new pots with your new glazes . Passing from test tile to pots , you got some new informations from the glazes and some surprises too ! Good luck :)
Something that you just said I think would be interesting in a few years from now when you have your wood kiln and other kiln types…if you were to use the same glaze and then fire them differently, it could make a really cool set showcasing the kiln firing type!
The generous education/information you provide is astounding. Grateful thanks.
I took a very basic pottery class a few months ago, playing around with shapes. Unfortunately we didn't get too the glazing since their kiln broke so watching this video about how much work goes into making a good glaze was very cool. I also find your voice very relaxing to listen.
Florian, loved this because this is the internal process that makes making so interesting and engaging. I really loved the yellow that was too toxic and the dark grey that was like touching a pebble. Thank you ♥️
man youre amazing willing to share the process in detail on each of your videos . Superb !!!
For the red, I'd call it Bloodstone.
You, sir, are a true artist. I admire your skill, but also your quiet, organized mind that can test and test and test until the result matches your vision.
This is so cool. I truly admire your experiments and your obsession.
I Liked the Black and Metallic at min 20:06. Reminded me of cooling Lava. Nice work with all the tests..they all look Great!
omg the white thet you chose for your ceramics is absolutely beautiful! good work! there is nothing better than a really good glaze testing and finding new glazes.... maybe even by accident. (:
This video is wonderful, I love that you to into such detail. Very informative and satisfying to watch! I have to say though - I LOVED the cobalt blue! Such a classic, eternal colour. And it would make food look very appetizing!
You are a wealth of knowledge!
I apologize for our language barrier. I really like your work. thanks for that. I'm also an amateur potter and we make two more notches on the samples to see how much it goes into the shard. soak the flank in manganese dioxide to see the reaction with the burel, and soak them so that one, two or even three layers are visible. and not completely down to see the flow. it's just a tip. you can see more reactions in a small place.
beautiful and detailed analysis
Only just chanced on this video and I found it very interesting, thank you very much for sharing your process and your thoughts!
Those yellows are quite warm and cozy. I really like the ones that have the crackle. They're always like looking into a little world.
Almost 30 minutes of glaze talk, thank you ❤ i like yellow/gold a lot, it had to be toxic of course 😅
Such an interesting and amazing insight, thank you! It makes me wish that i could start with my own glaze mixing right away, even if it feels a bit daunting still since i never created my own glazes before and don't know anything about the materials, process etc. But seeing all of your tiles is really inspiring!
I remember in high school pottery class with our resident artist who had been doing Pottery for nearly 50 years was cleaning up and consolidating buckets of glaze pouring one into another of the same but for one accidentally made a mistake and poured two completely different glazes together that looked similar unfired. we decided to just own the mistake and mix it up and fire a test dish to see what would happen and it was one of the most perfect coffee-colored gradients on anything you put it on. I made a tea and coffee set with that glaze and it was awesome. sadly it all got used up and we were never able to exactly recreate it. my mom still has that pieces all these years later.
Your videos are like meditations to me. I don't make pottery, but your hardwork and methodic ways inspire me. I really liked the black that looked like granit (the one with blue tones that didn't appear on the video) and the red one. Makes me want to try pottery. Thanks a lot.
Loved watching this process, reminds me of exploring glazes at school and the lustres. There are a couple of amazing teal and orange colours that reminds me of my dads old Citroen 2CV, so lovely more matt but beautiful
Really neat video. I know absolutely nothing about this hobby, but found your methodology fascinating. Great narration and editing. 🙏
The .1% cobalt was nice.
I like that grey too! It may eventually get used but it already looks as if I have a ton of glazes to mix up. Hopefully I'll see some proper results in the next month or so.
@@floriangadsby I'm sure you'll settle on something great. I'm just eager to see it. Few people that do what you do would share so much. It's a pleasure to watch you work.
I loved the black glaze with the blue tone to it. I thought it was wonderfully complex and three-dimensional, and I think it fits well with the glazes you currently use.
What a perfectionist. I appreciate it.
First video on pottery I've watched and this is so satisfying!
That Copper Coated is Just Like Gold😍# Excellent Work👍🏻❤️#Ultralevel In Pottery❤️
Well, it feels to me like the glaze that looks like the surface of a pebble should be named something like « pebble black » or something. I’m thinking the reds could be named after the pomegranate fruit.
Not that you should do what I’m a bout to say, but naming creations reminds me of two artists who used to name their art with completely unrelated names, such as Damien hirst. He named a taxidermied shark in a tank « the physical impossibility of death in the mind of someone living ». Or there’s the painter Magritte who would ask his friends for random names for his surrealist paintings, like « l’ami de l’ordre » or the friend of order in French.
Thank you for the video as always Florian
How does this not have more views?! This was so great to watch
I loved what glimpse I could see of the light turquoise glaze on the porcelain at 10:22 front row. That would totally be my color of choice for dishes, its stunning.
I also loved the second row on the back, that smaller porcelain piece at 10:27
I could also imagine owning mugs or dishes of that black metallic glaze you chose, the matte-glossy mix looks awesome.
Fantastic work!!!
ive never really made ceramics before or known about the “background” of ceramics, but i watched this whole video and i never knew that there are all types of glazes and that you can customize it to your liking. it was really eye-opening and i hope that i get to make ceramics in the future.
So nice and cool. Great video!
If I was a potter I think I’d get severely addicted to this XD such variety! Shame that the toxic stuff produces such cool results.
This is so informative and absolutely interesting! I have 0 education on ceramics and all you share is absolutely incredible 🖤
so systematic, I love your art work 😀
Thanks for another video Florian :)
I was wondering, as the years go by, how does the sitting position of throwing pots affect your back and posture?
Thanks for watching Jorge! Well, I don't get any real back pain, I can get a little sore after a day throwing or trimming though. As for my posture, I do hunch somewhat occasionally but I try my best to sit as straight as I can on the wheel/at home. I've seen potter's who have a bar they can hang from in the studio, which supposedly helps and my family are always telling me I should start doing yoga. Otherwise I do some weight training at home but nothing too serious. Appreciate you taking the time to watch as always 🙌🏼
Would love to see the video on what these looked like on full pieces.
For one of the most brown, Peat would be a good name. The olive yellow one reminds me of Agrinion olives. The metallic black -Pewter.. The red- aseel- is a type of rooster that is agressive. Shiplap would be neat for one of the whites, if a bit trendy I suppose. I know you try to avoid trendy. I know you mentioned avoiding the streaking in the one thick black- but it really looks like LEATHER! That might be something interesting to explore in more decorative pieces? Really loving your videos and your very quiet manner in discussion. Thank you!
Wow! I really love you´re videos! Keep them coming! Recently started up with ceramics again after like 18 years of rest :D This was very interesting!
Once again, I must pray to the Algorithm for putting this video on my front page. I watched and enjoyed every second of this video.
I don't know much about pottery, but I know its not easy to be an Alchemist. Going to subscribe for more relaxing wizard content.
Absolutely brilliant, wounderfuly informative video. I like your style. Oh the blacks are wounderful.
Amazing work!!!🤌🤌🤌🤌🤌👍🌍🇹🇯🇷🇺
This video is so EPIC!
Generally i prefer a more vivid colour palette but i really appreciate and enjoy the depth of colour and subtle variations your glazes have. The red you selected is probably my favourite, it is a really rich colour without being too loud
the pebble glaze is lovely
Question Candidates for your next Q&A (?):
Do you regularly/have you ever...calibrated your scale before weighing out fine amts? Scales weighing to 2 points can go out of calibration quickly...as much as .2 - .5g.
Trial: Do the same tile test but use a new and just calibrated scale. Compare results. Evaluate if there was a significant difference not accounted for by other variables...if at all possible!
This difference in my Canadian cannabis dispensary amounted to about $1k loss per month if I didn't calibrate regularly.
Just a thought.....
Love your videos✨👍
Woah! That's crazy. I have calibrated it once so far and occasionally it just refuses to measure anything until it surpasses 1 gram, I think I should probably invest in some superior scales. The answer to most of your questions is that I haven't tested enough to run into any issues. I haven't had any problems mixing up larger batches yet but I suppose small variations could exist. The other issue is that raw materials change from time to time, so feldspar I get from say, Spain may suddenly come from somewhere else, and the chemical composition of the new feldspar may be very slightly different or even processed in an entirely different way, which can have drastic consequences. The scary thing is we have very little control over that and over the years raw materials have started to become more and more processed for bigger industries whereas us ceramicists usually prefer the more unrefined stuff. It's a fascinating topic and one I've heard so many scary stories about from fellow makers. Thanks for watching Jack!
@@floriangadsby Thank you for such a cogent response! Cheers! 😊✨👍
...by far my fave channel!
I don't share your tastes in glazes, but this was a very fascinating insight on the work that goes into coming up with them!
truly amazing
Great informative video , thanks 😊
I absolutely LOVED the glaze at minute 23:15. Do you share recipes? I would love to have this recipe, it is gorgeous. Thank you for all your tests, it's fascinating to watch you work. I've learned so much from you.
Aaah florian the joys of cone 10 reduction firing (personally a huge fan of soda, esp Lisa’s pots - so i’m excited to see when u start soda urself). i only have access to ^6 reduction (so my options are limited, but sooo deeply grateful for access to reduction) and a lot of my midnight meanderings are spent on glazy! Thank you for sharing such a detailed explanation esp. what you are looking for. looking forward esp to see your tall footed pots in ur new color. i’m sure they’d look amazing. i LOVE rutile, but Titanium can be a real kick in the butt.
I cant choose my fav. it’s like which one is your fav child. esp when it is accompanied by the story n thought process of its creation.
I’m excited to see you venturing out with different colors. Sometimes just the color difference makes the pot look so different.
Personally i prefers the traditional muted mottled colors. i prefer a quiet pot which is breathtaking in its simplicity, but the pots i make are nothing close to what i like since access to the type of firing defines my style. i cant stop drawing/carving the moment i finish trimming when that was not my intention to begin with.
All your videos are VERY satisfying for pottery nerds like me who don’t have access to an MFA. I’ve picked up so many pointers from you!!! 🙏🏾
The red one looks amazing,what a surprise.
What a journey! 👍🏻
the glazes look amazing
You are incredibly gifted! UNBELIEVABLE! This was hands down, the BEST GLAZING VIDEO EVER! Your cinematography INCREDIBLE! Your explanations, were so easy to understand, if you showed every single glaze I would watch for hours easily! You could even make 5 shows, one for each firing, I would watch them all, nobody ever shows the up-close and dimensional with the lighting just perfectly revealing every aspect of the surface as if we were seeing it with our own eyes! Its like we are on a field trip to England visiting your studio! Thank you so much for sharing your incredible collection of impeccable work! Just absolutely Brilliant! My question to you is will you be keeping all of your test tiles? Also how will you be storing or displaying them? Will you be sharing any more recipes of the reject tiles? There was one that was powdery blue that turned orange on the edges or rust… so beautiful! Ive been to Glazey but usually I am very lost there, but because of this amazing video i will try again. If you took these tiles and published a book of recipes and photos of just your rejects it would be a best seller! Thank you so much! I don’t have a favorite because i love so many, the black and white are beautiful but I also love the crackle glazes so much! In all the colors! Thank you for your incredible channel, and for generously sharing your beautiful work with us in such a skillful and fascinating way!
This is fun to watch~
Impressive indeed!
This is so interesting and relaxing. You sound like an alchemist!
Thanks for this very interesting and beautiful video as always. Your energy and time investment bring your work to an upper level.
For your black glaze (DBB4) I thought “equinox black” could be a good name, due to this mat/shiny effect.
Hayran kaldım. Gercekten hepsi birbirinden güzel.
Might be nice to get a set of letter punches to put the recipe code on the test tile
Great idea!
I feel like all of these colors are great 😅 I love the vividness of things though, like the cobalt. As a leatherworker I, too, have my color palette I stick with, so I get what you're saying. It's just funny how different our opinions are on what would fit our palettes. Either way I know the glazes you pick will make beautiful pieces!
I really like the glazes you designated CBB2 and CBB3. CBB1 looks like it would be a beautiful black if you could find a way to keep it from running. Thank you for sharing this.
Worth the wait 😊😊
Pleased you thought so! Thanks for watching, Rhea.
12:25 Brooo if you get that cobalt to break greenish, with the crackles and all you said you enjoy, I think you could find a great blue.
13:13 loved this one! Still before I think I imagined something like that but breaking greenish intead of brownish
I am obsessed with the cobalt! I know it doesn’t fit your glaze profile but perhaps a special edition? 😇
