6713/8 Glossy yellowish with blue crystals

glaze 6713/8, detail
One of my most popular crystal glazes based on zinc and lithium. Too thick it will run a lot, but it can be controlled very exactly after a few tests. Always spray the glaze thinner near the bottom of the pot. 1260oC with 1/2 to one hour at the top temperature. Does not need a slow cooling. You can also try other combinations of coloring oxides.
