- I was messing around with some slip I had added colored Oxides to in an attempt to add color to another project. That did not work out too well, but led to something else.

Thank YOU for watching!
I was just at the store today wondering if I added oxides to slip. These are beautiful.
Thanks. I have to try some more.
Like the batman belt
Curious what the resulting colors would be if you did any reduction firing...using raku clay or just depriving it of oxygen. Maybe none, but might be worth playing with.
Good idea. I have a raku kiln full of stuff waiting to be fired. I'll stick a piece in and see what happens.
Very cool wonder if these oxides are the same as old painters pigments. The ones they use to mix by hand before it was computerized for color matches. Or if there is other additives like plastic that would throw it off in firing...also if powdercoating pigments have plastic in them then they wouldn't ever work as a colorant in ceramic glaze's
Have you ever tried just slip mixed with different color glass frit?
@@sam111880 I have tried different glazes, mostly 06 glazes and had some success. I have not tried it in slip, but I will give it a try. You are right about owder coating paint. It will not work with ceramics or glass, at least from the firing standpoint. You might could do something with it as a coating and heated to the recommended temps though....another idea! As far as the "oxides" go, they are standard oxides and mix very well with the slip. Sometimes the color changes.
@@CaptMike Have you tried mixing fine grain frit with water and using that as a colorant. I imagine it would work but maybe not give you proper colors. As it is like putting a colored glass layer on top because its just frit. Also seems as these colored pigments /oxides are just rock ore oxides that one obtains thru mining in various places. It seems pigments come from more rock ores and dyes come from more plant/animal sources.
Once you have the pigments and dyes you in theory should beable to make any grade of paint , ink , fabric dye ,...etc by mixing proper additives as well as making it water based , alcohol based , or oil based paint. Of varying thickness/ consistency. Slip is nothing special so you will probably succeed with coloring them sense it just liquid clay.. So you should beable to color blocks , liquid of any consistency ,...etc.
@@sam111880 The only problem with coloring slip or clay is that whatever colorant you use must be able to stand the heat. Some of them will simply burn away while others will change colors.
What was the percent by weight in color did you use if the mason stain?
Samantha, I don't remember. I usualll just add color uuntil it looks right to me.
Did the colored slip stain your plaster mold at all?
Yes, a little, but the color transfer to the next piece was minimal. The glaze should cover that with no problem. If in doubt, make a small simple mold and experiment.
What is cone 04 or cone06? What do you mean is it related to fire degree?
Yes, the "cone" refers to the firing temps. Go here for a listing of the cones and related temps: bigceramicstore.com/pages/info-ceramics-maxcone
Where do you get your oxides from? would love to try this, am here in GA also.
Have you tried using more of the powder?
No, I have done this one video but need to update.
Is it possible to pour wax in this containers? Or the material will absorb the wax? Thank you
If you are refering to the plastic containers, yes, you can pour wax into them. When cool the wax should pop out.
@@CaptMike hi. No! I refer to the ceramic containers you made!
@@CaptMike the ones not fired
@@cobzarualexandra273 If you use a container made of ceramic clay, but not bisque fired it will come apart. After it has been fire to cone 04 (or there abouts) it will still be porous, but will hold the wax and will not come apart. With the addition of a glaze and fired to cone 06 the container becomes less porous and makes a great candle container. Hope this clears up things for you.
@@cobzarualexandra273 Bisque fired and glazed clay containers will not absorb any wax. Make lots of candles....Enjoy!
Does anyone know how to actually make yellow slip fire to a yellow/honey/gold colour? I just had a disaster firing where all my stuff came out pink... lol
If you add the metal oxide powders to your clear glaze you'll have coloured glazes just like your commercial oxide based glazes or at least very close. Commercial liquid glazes may have some additional glazes.
Try also throwing the oxide powders on top of your combustibles in your raku burn
Great idea, thanks.
do you think its food safe?
Unless you are using s glaze that contains something that is not considered food safe, then I would see no problem. Remember that a clay body that has been fired to cone 04 has not totally vitrified and may soak up liquid. To make a clay piece that is ideal to cook in or eat out of you should use a clay body that will fire to full vitrification or about cone 6.
Can you use the same method to color casting slip?
Hi Taylor, that is what this video is about. Sorry if I did not make that clear. Just start off with test pieces and add small amounts of the colorant you wish to use (usually oxides), mix well, fire and see if the color comes out right. If too dark, add less color; if too light, add a little more. Let me know how it works out for you.
@@CaptMike Got it, thanks for responding :) I wasn't sure if it was casting slip or just regular slip..or if there is even a difference between casting slip and regular slip..I'm fairly new to ceramics but I want to try some marbling effects using casting slip.
@@taylorweaver2166 Slip does come in different compositions just like a clay body. There is low, medium and high fire clay. Also porcelain. When you start, stay with the high fire if you can. You don't have to fire it high, the the option is there is you want to use it. The other type of slip I have seen referred t is slip made by liquefying regular clay to use as a gluing agent for joining two pieces of clay.
Capt Mike ok, great! Thank you!
How do you use slip molds?
Slip molds are made of plaster which absorbs the water from the slip clay creating a shell. The mold can be either a single, double or multiple piece mold. You pour the liquid clay slip into the mold and wait awhile until a shell, usually about 1/4 in tthick forms. Then you pour out the remaining slip and wait until the shell is dry enough to unmold. Hope that helps.
What is frit?
Frit is crushed glass. It can be purchased or you can make it. I will do a video on how to make it soon.
I have oxide's for my cp soap
They will work.
My guess is that black is manganese, not iron based. Others will know.
Thanks for the comment.
Sorry, you don't demonstrate your work
