My celtic mugs are out of the kiln, and there are more in the bisque fire. The glaze is Yellow Winnoker, a really nice glaze made up by my friend Renee G. I tend to fire everything the same in batches. These mugs took a while to carve. I went on a celtic knot craze which is also evident on the last genealogy tree I painted. It should be on our familytreesandtimelines.com website soon.
