I posted the firing schedule on another thread. it is a more involved firing schedule than a typical cone 6 firing. This is because the crystals need time to develop and they seem to develop more in the cooling stage. Crystal glazes are usually cone 10 glazes and can be both tricky and difficult to work with. Laguna came out with a cone 6 line of crystal glazes that are pretty nice but because they are so runny you need to prepare your piece for that- ie a pedestal with a catch basin for the piece to rest on when firing. they will still stick and you need to keep that in mind when you are using this glaze.
Now Coyote has come out with a new line of cone 6 crystal glazes that look pretty nice. They swear they dont run but im skeptical which is why i was hoping someone has already tried them and can relate their experiences with them. I notice that the Coyote glaze firing is a little closer to cone 6 than the Laguna line and that their recommended firing schedule is a little different. They even go so far as to say that you can just fire with a normal cone 6 fire. My experience with the cyrstal glazes has been the trick is really in a slower and longer cooling period for the crystals to develop and grow.
anyone care to share their experience with crystal glazes - both the hi fire and mid fire ranges ?
