Hello! I got all the ingredients today to mix my first batch of glaze - Kitten’s Clear - from John Britt’s book on mid-fire glazes. Trouble is, the recipe calls for an added 2% of bentonite and the girl who helped me gather all the ingredients either missed/skipped or forgot it. How essential is the bentonite? Can I proceed without it? I plan to add some whiting and stain. If it’s essential, can someone link a good place to buy some online? I actually have a 100% bentonite clay powder I use for a face mask - would that work as a replacement? thanks!
Need some input, point/s of reference. 1. Do you add bentonite, EPK, or gums to your glazes? 2. In what amount do you add to the final (dry) batch weight? 3. Do you add more for high magnesium or sodium glazes? 4. Have you had problems with bentonite clumping? 5. Do you rely on additives to achieve viscosity? Nerd
I have been making porcelain, and i was using regular bentonite, and noticed dark specks in the clay after firing , wo i decided to mix three grams up in to one cup of water and stir it for three days off and on but what i found out was after i poorer it into my clay test all the heavy junk settled and never made it into my clay body- so now i know this stuff is not so refined not that it can't do the job, I am just going to have to wash it real thin and let the junk settle you can see the black grit in the bottom of the cup
