There was a bit of a discussion on another thread about crazed glazes on functional pots and whether or not this is an issue if the clay is vitrified. For the most part I make functional everyday pots, vitrified clay, and my glazes don’t craze. I was taught that functional pots shouldn’t craze, significantly weakens them and craze lines can stain. If the clay isn’t vitrified then crazing causing other issues like moisture getting into the pot, get really hot in the microwave and possible bacterial growth in craze lines. Also, not sure how pleased customers would be if my glazes crazed after use. I’m guessing that for the most part if they didn’t buy a crazed glaze to start with they are not going to want it to craze later on. I could be wrong, I don’t know but I’ve been doing it like this for years and perhaps should rethink this. I think crazing on a coloured transparent / translucent glaze is beautiful.
So, if you make functional pots with vitrified clay, for your own use or for sale, what do you think? Crazing inside, outside, neither, does it matter?
