What are some stoneware glazes?

Glossy yellowish with blue crystals

Crystal glazes: Glossy yellowish with blue crystals
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.
potash feldspar NR 27,60
quarts (flint) 32,20
dolomite 3,48
zinc oxide 18,70
barium carbonate 4,44
china clay 2,75
lithium carbonate 6,82
rutile 4,01
cobalt oxide 1,06
