Nice peeling, eh?
This Flashing wash actually works well, (well... it works well sometimes), I just have to figure out how it works and why.
For me, this is why studio ceramics is so much fun, play, test, adjust. Each load is a gamble.
Learning from the losers is what makes things interesting.
This was applied too thick and fired too wet without being allowed to completely dry. With the high amount of clay in the mix, it just shivered off. Gotta let it dry completely... can't let the surface boil... I think.
