You know, considering how much focus there is on ancient kilns and furnaces a collab with primitive technologies would be great
Too bad he's in Australia.

I was a professional glass blower for 15 years. Glass is incredibly complicated. Getting quality glass from raw batch is a real craft. Thanks for the video and thanks for the tenacity!
As you know temperature control is half the battle.
@@hakarthemageyes, we know. Don't be pedantic.
The Romans used coal, that they turned into coke! Not the king u put up your nose, put into a furnace and blow air over it and it reaches hightemps fast!
@@joshschneider9766 I don't think that word means what you think it means, as you're the one being pedantic there lol.
The taller your chimney is, the stronger the pressure diference it creates when you heat it up. So if you think you need more airflow to make your wood burn more cleanly, make the chimney taller. Hope this helps. Good luck!
Forcing air flow catalyzes burning, but at the same time introduces cooling. How about preheating blowed air somehow by second furnace with isolated air path?
@@silotonuse residual heat from exaust gas to do that
@@waynebimmel6784 A heat exchanger to preheat combustion gasses from the exhaust would be an effective, but to my knowledge entirely modern, method.
@@siloton The flames shooting out the top of the chimney tell us the fire wasn't getting enough air. The light from the flame is incandescent particles from incomplete combustion. Best heat requires a balance, enough air for complete combustion but no excess.
yes taller
Hey you actually managed to go from raw ingredients to aqua glass in one.
Huge step forward. Can't wait to see the next one.
This is what success looks like. Tiny iterations working toward victory, and even here when you've actually DONE IT, it still sin't going to feel very satisfying because it's not perfect. Keep going and see if you can't achieve optical quality glass, but failing that, the stuff you made looks up tot he caliber of the ancients, and that is no small feat. Well done.
The part about how glass goes from brown, to amber, to green, to blue absolutely blew my mind! I’ve seen all these kinds of glass all my life but had no idea what made them happen, and now this even makes sense as to why so many beer and wine bottles are dark brown - no reducing agent to make it clear!
Modern glass is made with chemicals added to get uniform colors. Beer and wine bottles are made dark to block UV light which can kills the yeasts needed for the fermentation process.
@@Domarnett I’ve seen some pretty inconsistent shades from British breweries! Usually the fermentation is done before bottling in those beers as well. I know that’s not so much a thing in wine though and it makes sense why they’re so much darker as a result.
@@kaitlyn__Lin beers the bottle are brown because the UV light damages the hops.
It's the volatiles (oils and whatnot) in the hops reacting to uv that "skunks" beer.
@@DH-xw6jp certainly not denying it’s useful, just sometimes the amount of brown is inconsistent like these samples rather than one solid colour just like wine bottles. I always loved the light shining through “blotchy” or “stripey” ones as a kid. And obviously the iron isn’t just “coming with” the materials like this sand was, so it’s always an additive, and iron being brown isn’t surprising. But it’s cool that iron can do the whole range, I always assumed the blue glass was copper.
@@kaitlyn__L sorry, i meant to reply to the guy saying they were brown to stop the yeast from dying.
Glad to see that you made it out here to the Corning Museum of Glass. It is one of the best hidden gems here in Upstate NY and a great source for information on the history of glass and glass-work. For those who are curious about glass making and would like to try it, the museum also offers classes where you can get similar hands-on lessons as well as make various glass crafts. I've personally gone several times and made my own wine glasses, glass pumpkin decorations, glass snowmen, and even Christmas ornaments to gift to friends and family.
Geez, I've lived in the area my entire life, and didn't realize they offered classes. Thanks for the tip!
@@Nono-hk3is Yes, if you go to the museum's website you will find on it listings for their Make Your Own Glass, where they list the small glass crafts, and the listing for the Studio, where they list the different classes. Classes are multi-week affairs whereas the Make Your Own Glass events are usually a single evening or afternoon event.
I’ve gone twice. One of my favorite museums.
yea it’s a really cool museum
I have wanted to visit there forever! That is the most incredible collection/exhibit of glass ever!!
I've seen a design for a high temp clay furnace like this that basically use an insulated double wall. There is an inner chamber for the fire and crucible, and an outer shell with a few inches of gap between them. The gap is then filled with loosely packed white ash from previous fires. The small air pockets in the fine powder and high temperature tolerance make an insulation that is high performing for something so primitive
The Corning Museum of Glass is a surprisingly awesome place. You might think it would be a "cool for 20 minutes and then you've seen it" thing, but it's at least a full day experience. Lots of cool stuff there, not to mention the classes and such.
Dude I know! I live only like 2 hours away from it so every summer I’ll go over and take a class for fun and then just spend the rest of the day there. There always seems to be something new to learn every time I go, they’re always changing around what they’ve got in the smaller exhibits
@@ImmortalLemon It's a bit more of a drive for me than that, but the time I went I was blown away by how much stuff was there and how interesting it all was. I only got to do one small class, but if I lived closer or had more free time I'd be taking a bunch more.
@@Zelmel I hope you get the chance to go back more in the future. Everyone deserves to learn an explore their interests
"There's this guy who nobody seriously doubts existed and was objectively the most influential person in all of history and we pegged the date to his birth for 2000 years but that has fallen out of political fashion and I'm either petty or a coward so I'm going to pretend it didn't happen"
Everything that comes out of the mouth of a historian who says BCE is suspect.
@@fisharmor bro wtf are you even talking about right now? We’re talking about a glass exhibit here and nobody even knows how to interpret whatever you’re regurgitating from a podcast right now
Andy is always so serious about these projects. They joke around a bit but the shear joy on his face at 28:29 is a rare treat. Thanks.
It was a good day
Your consistent effort to create clear glass throughout all these years is really, really inspiring!
I think the extra step of making charcoal might still make sense at your scale. It will ensure the fuel is all extremely dry and will burn hotter, which would save you a bunch of time getting up to temperature on glass day and reduce the chances of a poor wood supply keeping you from succeeding.
If you were cranking out glass every day, perfecting the wood fire is obviously a better option economically, but when your goal is successful glass blowing and not being financially profitable, take every edge you can get.
Plus commercially purchased charcoal can be cheaper than raw firewood nowadays
i saw a video of an afghan man blowing glass, and he just put firewood in it!
Mined coal or bituminous coal is also an option.
Would love to see you making some moulded glass items like those in the museum as the step before blown glass as well!
This is probably my favorite video you've made so far, it really shows the fruits of butting your heads together with other people to come up with a solution as they did in older times. It's always about finding the best way to make things easier when it comes to projects like these, isn't it? I loved how just moving a bunch of rocks in the right shape gave you a better result than what you had with a modern tool blowing air in, a great example of working hard vs smart!
Really amazing dedication as always from this channel! You probably heard about them at the Corning Museum, but early blow torches invented during the Renaissance made working glass way easier and way more fuel-efficient. I have a few videos on my channel of my reproductions of those blow torches if youre interested. they were used for making all sorts of things from chemistry equipment to the first microscopes and can be really incredibly powerful.
I just discovered you yesterday and now here you are
@@mikeyjohnson5888 😂wherever there's mention of recipes on ancient stone tablets, I am there!
The Corning Museum is a wonder! My wife and I spent almost a week there and didn't see everything. We did come away with a couple of glass bowls that we saw being made by the glass artists. Your technical deep dive into the process is very illuminating, and I really admire your dedication and determination in the videos. And you did some quite good first efforts at making decorative objects in clear glass.
Out of every skill you have gotten from this experience, none compare to how naturally you taken to glass. Glass and Flint napping have to be the two skills that you have the ability to master.
I have loved following this channel through the years. Keep it up Andy!
A completely unexpected Collab lol love save it for part's content, very interesting to learn how satellite data works
Your comment about glassmakers moving from place to place where there was plenty of firewood available, perfectly describes the German medieval "Waldglas" manufacturing ("Waldglas" means "forest glas).
So hyped to see saveitforparts on here! Great to have more Minnesota peeps get a highlight
That video was on fire!

This channel is exceptional and represents the best of what the internet should offer. Outstanding work, as always.
I’d love to see an episode on canning (like mason jars). Lots of early ones were clay. Wax or rubber can seal them. It was a major step in humanity, the ability to transport and preserve “fresh” foods.
I found it interesting to think that very fine clay pieces have existed since before written word and yet humans spent literal millennia developing this hot, dangerous, expensive, difficult art. And overall none of it accomplishes something clay and iron can't, until relatively recently with scientific glassware and high pressure vessels. Imagine taking a mason jar to these people thousands of years ago, you'd be a god lol
It’s hard to do that and not kill yourself, like he almost did when making a sandwich from scratch.
One thing they don't talk much about is how badly scarred ancient glassmakers were. Burns were common and so was lung damage from breathing fumes and heat. At those temperatures, the furnaces could fail explosively if just a small amount of water hit a hot spot. So, it was a dangerous occupation. I'm glad you got through it with minimal harm.
I can definitely attest to this, especially when we were using forced air. I had very little arm hair for a while.
Oh shit he’s back! Haven’t watched in a couple of years but love all the content I’ve seen! Can’t wait to binge and catch up
I love that your reaching out more to experts in the fields of the things your trying to make. You've done it before but it's Really awesome to see. And to really learn about the history from people with real experience
Those flames shooting out of your chimney suggest either there isn't enough oxygen prior to that, or your chambers need to the longer to allow that combustion to happen inside the structure. You're wasting all the heat of flames coming out of the chimney. If you can make the height difference larger, that will help. you could also experiment with pre-heated secondary air intake injected after your primary burn chamber to ensure full combustion. Look up rocket stove design.
I appreciate how you went classical tech on this. I've tried to go classic on a variety of metallurgy projects with much less success, always resorting to purchasing materials pre-refined, or using electric/gas heat. I eventually scrapped the classic methods and went with a time/money/efficiency based lab. My thing is refining precious metal, and figuring out what byproducts might be used for.
This is very cool. This is the type of channel that should be huge. Unfortunately, the world is very foolish.
The part of the book saying to make a sheep sacrifice to ensure a successful attempt reminded me of the thought emporium saying how microbiologists where superstitious and that if you told them that sacrificing a goat would ensure their bacteria didn’t die they would start keeping a pen of goats in there lab
I love complex glass objects and I have a collection of baubles, dishes, pipes, etc. and watching this it makes me feel like ancient royalty to have such delicate and hard to make objects
Excellent episode - I love how he takes us along for the ride. Also, 3:36 has to be one of the calmest explosion narrations on CZcams in recent memory - doggo went from chillaxed to nope in no time flat.
Been looking forward to this video since I saw the short on it!
I’ve been following you on this journey for a while, its amazing what you’ve accomplished!
I took 4 semesters of glass blowing in collage. I might've cackled a bit when watching him get a lesson from a master. It's very hard! Good work though! This was fascinating!
This is my favorite series you have been doing. I have been following you for years, and I never miss an upload, I wasn't here for the original sandwich, but it wasn't that long after that. It's amazing to see how close your getting.
This was a great an educational video! I really liked the format of interviewing experts, showing the research, trying the technology, and then having a go at it yourself with the acquired knowledge.
Excellent, one of your better videos in months I think. Glad to see you revisiting the glass project.
Good thing civilization had more skilled people than this guy making glass thousands of years ago or it would never have happened.
I enjoy how Andy collaborates with so many experts to show the building of these objects that we commonly take for granted.
Really puts into perspective stuff like the Lycurgus Cup considering how hard primitive glass is to make, and how we cant even recreate the cup with modern glass making tech.
People are like "wheres the proof of these so-called ancient advanced civilizations?" And i think the Lycurgus Cup is one such piece of proof.
Outstanding! Great job everyone!
Duuuuuuuude I'm so proud of you! You've been trying to get over this hurtle for so long and this episode had major progress. W2G! Love the channel!
Congratulations! I loved watching your journey in this video
Your progress has been truly incredible
Love these longer formatted videos! Great work so far, I recently started learning how to glassblow at my university too and it definitely harder than it looks
That’s great progress!
Sounds like perfect winter time activity
Nice videos:) hope youll get to modern tech
I love experimental archeology! You did amazing and congrats to finally nailing it
When compared to before definitely feels like you have improved a lot.
This is insane! It's been amazing seeing your progress during the past few years with glass, and this seemed like a major leap! Can't wait to see what you'll accomplish next.
I love glass-blowing! I can watch glass working for hours. This was very informative. Well done!
Great video, really enjoyed it. Nice work making the glass! Best of luck to you guys.
Great episode!!
Absolutely fascinating!
Love the volcano furnace, that thing looks crazy.
This is pretty amazing! Good work!
Nice work!!
Bro you have been searching non stop for that perfect glass hand-made using acient techniques amazing
Damn, that quick clip with you and Grant really brought be back to the old King of random days
Great episode, I really enjoyed this!
You are teaching us everything thank you very much.
This was one of the best episodes yet!
Congratulations on the achievement! I know how long you've been working at this, and it's great to see your journey of learning. :D
Amazing process, like the magic
You are a real inspiration
This was an amazing video! Super informative and interesting!
Wonderful video!
This was such a great episode.
This is so cool!
Pretty amazing endeavor
Ouch… seeing The King Of Random brought back some childhood memories. RIP man
it may NOT be much to look at, but it is a *MASSIVE SUCCESS!*
Congratulations gents, ever forward
Good for you and good for us!
Just insane how complicated is glass making. You'd think it's just some sand but nope! Another great peek into humanity history, love these videos!
I gotta say...this really conveys just how crazy the effort to make ancient glass must have been. The investment in time and materials in the ancient world would've been huge.
Cheers, great video.
tremendous effort
CONGRATULATIONS ON THE HUGE PROGRESS!!!!!!🥳🎉
Hey man love the videos! Keep up the great work!
08:35 I live in the area, Corning Glass is amazing! I've made a few of these flowers, so freaking cool.
How I do love thia channel.. this is what CZcams is all about for me ❤
This was a wonderful achievement! Can't wait to see the next steps with it!
Reasons I want to learn this.
1. Imagine selling fantasy glass bottles that were in fact hand blown.
2. I always wanted to learn how to make said bottles.
3. It just looks fun.
Reasons I don't wanna learn this.
I know its going to take a long time.
I know I will end up burning myself badly
I know it wont be as fun as it looks.
I was like "Museum? What's that gonna teach you?" Now I want to go there. Living museums are the best!
Congratulations for the success. Finally after many years.
Awesome video. I appreciated the way you tried to recreate conditions. That museum looks great. Now I want to eat cereal.
Right on, these are some of the best videos, I can’t wait to see what else you do with the water wheel, possibly making an electric grid powered by hydro? Make a light bulb (I did this in grade 7 with pencil lead, a jar, and batteries) and Maybe attempt a copper wire? Try to take the energy of the water and turn it into a light source. Just a thought, love the vids keep it up
I think making a magnet might be the hardest part.
