Wet to Dry
Clayclubbers, Do any of you know of anything you can add to a wet glaze mixture to reduce wet to dry shrinkage? I have buckets (and buckets) of scrap glaze, Slopadon (a very nice, olive celadoney glaze in cone 6 electric) that shrinks and cracks a lot after I apply it to bisque, and later there are tiny, but annoying, bits of crawling out of the glaze firing. I'm thinking there is a fair amount of clay in there (I put slips and sigs into Slopadon, too) which made me just think maybe green glazing could be the answer. Any suggestions for chemical additions? Thanks!
