Glaze Tests

I've been mixing some new glazes and running tests on them and this Speckled Glaze looks promising. The test tile looks amazing! I also tested a thick coating on a coffee mug and it ran like hell and glued itself to a kiln shelf, so more work needs to be done. Still, this one is luscious!

I am also curious to see what would happen with iron oxide or cobalt carbonate as a colorant. There may be more to see from this glaze. I'll keep you posted.
