OK, I've made John's SG 12 oil spot glaze and the cover glaze for it that has the poetic name of 215.  I mixed up some Bailey's Oil Spot glaze and tomorrow I'll make the Chinese Crackle to go over it.  I'll select vessels to start glazing and I'll do a cone 10 oil spot glaze firing this week.  The pictures should be dazzling.  I hope they fire well. I hope they come out beautifully.
