I've been looking for a crawling raku glaze and this one was just recently posted on Clayart, although it is actually a cone 05 glaze from SDSU called San Diego State University Crawl. I'm going to try it this weekend in my wood kiln and will post a photo next week.
47 Gerstley Borate
31 Magnesium Carbonate
According to the person that posted the recipe, "The lower you fire it the more crusty it is (cone 07 or 06) and it is called "Lichen" at that point. And as you go higher it will melt more andbecome a "Crawl" glaze (05) and higher it will be a "Bead" glaze."
Welcome, 2018!....oh wait - I've been wanting for years to get back to doing art fairs. Now it's happening! Unfortunately the things I need to do to make it happen, need to happen NOW...
