Food Safe Glazes

Recommended Posts

I'm looking for the food safe guidlines for glazes.  I'm in the process of mixing up glazes from scratch and need to know what to lookout for.

Currently  i have a base that is:

EPK            30

Frit 3110     20

Gristle Boriate 50

I assume this is a cone 6 glaze? If you put this glaze up against a limit formula, you'll see that it's quite low in silica, which can affect the food safety of the glaze. The only way to know for sure whether or not a glaze is food safe is to have it tested by a lab. However, with knowledge of glaze formulation you can formulate glazes that are likely to be food safe, which will save you a great deal of time and money before shipping tests off to the lab. Invest in a good glaze formulation book like Mastering Cone 6 Glazes as Marcia suggested above, or Clay and Glazes for the Potter by Rhodes, of Ceramic Spectrum by Hopper.

Look around the "In The Studio" and "Technical" forum sections. This subject comes up a lot and there is a lot of good general information hiding in the threads already in place. Use the forum "search" function.

 

best,
