2024 Microcrystalline Stoneware Glazes 

Food and dinnerware safe are 2 different things in Mayco's definition. Food safe refers to the leaching of lead and cadmium of a fired glaze and is maintained by the FDA. Dinnerware safe has to do with the surface durability and characteristics (does it hold up to acidic foods and are there any cracks or crevices that may be difficult to clean properly). All of our glazes are food safe, but that does not mean all are dinnerware safe. Micro Pearl is the only one out of the micros that is dinnerware safe. The non-dinnerware safe glazes can be used on the outside or below the lipline of dinnerware pieces where it will not come into contact with food.

What temperature do you consider a “hot” cone 6? Thanks!

A hot cone 6 would showcase a slightly slumped witness cone rather than a strong arch. You’re aiming for somewhere between cone 6 (2232F/1222C) or cone 7 (2264F/1240C). That could likely be reached by firing to 2232F/1222C with a 10 minute hold, maybe 2250F/1232C, possibly 2220F/1215C with a 25 minute hold. This will all depend on the heat work happening in your kiln and the only way to confirm it is by using witness cones. I would honestly recommend to just fire to whatever a normal cone 6 is for you to see how the glazes perform at that temperature and make adjustments if necessary.
