Second Saturday Raku February 12 went very well. Michelle Gomez Houlk and I started firing about noon and finished about eight. I did a test firing of the new top hat kiln I built the week before on Tuesday. Derrik asked if he could put a plater in it so we glazed one of his platers with my new batch of Molly's Matt. I had to go to work before it was finished. The plater stress cracked and the molly's mat bubbled. So Friday remixed Molly's Matt, and mixed up a new recipe for white crackle. I renamed the old Molly's Matt, John's Mistake its copper mat flashing purple with silver and has a bubbly texture. It's very nice texture glaze no idea what I did wrong. I am throwing out all the other recipes for white crackle. The recipe I found in Ceramic Monthly for White Crackle has blown them all away.
