Hey yall, I am a student and currently have a glaze making assignment for my class and I found a recipe that goes (in grams): custer feldspar 99 talc 63 silica 48 EPK 45 Whitening 36 zinc oxide 9 +22.5 titanium oxide 6 copper oxide black 6 copper oxide red I got through making most of the recipe and then found out we dont have the zinc oxide, is there something I could replace it with? I dont care if it ends up not being the color I want as long as it ends up as a high fire glaze. Im very new at this and have no idea what Im doing, please help.

Hello! I've decided to start using flamware clay to make cooking pots and I'm wondering if anyone has any experience or knowledge to share. I worked with an artist for several months who works with flameware so I know a fair amount, however my knowledge is limited to her techniques and glaze recipes. The artist I worked with soda fires her work to cone 11. Has anyone tried firing flameware in a wood kiln? Thanks!

Hello Everyone, I was looking at this commercial glaze: https://www.scarva.com/en/Scarva-GZ2214-Iron-Reactive-Glaze/m-5060.aspx and was wondering if you could tell me which component/property of this glaze made it 'iron reactive'? I would love to locate a glaze recipe with the same effect that I could try, or develop a glaze on my own. Thanks!

I have a wonderful aqua glaze that has been reliable for years but now pinholes consistently. I fire to 2185 w/a 30 min hold, slow cool in a Skutt electric. The recipe is: Flint 26 Laguna Borate 22 Custer Feldspar 20 Frit P25 13 Neph Sy 9 Zinc Oxide 7 Talc 3 100 Add: Copper Carb 2.5 Any ideas for why this is happening or how to fix it?

As i understand it, for glazes that settle out to much, Epsom Salts can help with Flocculation, what I can't seem to find is how often one would have to add the epsom salts to maintain the effect. I know it could be simply "as needed" and I could experiment on my own, but I like to know as much as possible before trying something. Is it just a few days or a few months? Thanks!

Hi, I have been testing for quite some to trying to get a light grey glaze with white speckles. Can anyone make any suggestions for a satin Matt grey glaze. For the white speckle I was planning on trying molochite but any suggestions would be greatly appreciated.thanks Jo

What The Heck is Glaze Chemistry All About? Sharon Art Center Campus of New Hampshire Institute of Art Professor John Baymore This one day, seminar-type workshop will provide participants with a basic understanding of the core concepts that can impact the creation, use, and evaluation of ceramic glazes for studio use. The instruction of the widely popular ceramic chemistry calculation software, Insight, and its priciples will be presented. Troubleshooting of fired results, “food-safe†qualities, health and safety, legal requirements, and ventilation concepts will also be touched upon. Handouts will be provided to all participants. Students are encouraged, but not required, to bring a PC or Mac laptop to test out a trail copy of the Insight software. Prerequisite: Intermediate ceramics skills.
