What are some stoneware glazes?

Recipe: Blue and yellow crystals

Crystal glazes: Blue and yellow crystals
A semi glossy crystal glaze based on frits and zinc. It tends to run not too much, but spray it thinner near the bottom of the pot. 1260oC with ¾ hour at top temperature. Usually it behaves very good. The crystals can be very complex and large. Use it alone or together with one of my 6713-glazes. If you reburn it the crystals will be smaller.
