Torch fired large enamel dome… fired so smoothly with clear flux, added a white layer which really was difficult to fire and discoloured into quite a sweet bluey grey, stoned down it took on some marvellous colour… until the cracks!! The unlabelled white enamel, I am pretty sure is hard firing and with the soft flux, the expansion rates of the two enamels have created this problem.
Its given the whole dome a really interesting overall effect ….
some white has seeped into the cracks … if I can refire with a different white, into the creases and holes this may produce an interesting overall result. If its just going to keep on cracking, I’ve got a lot of enamel to remove. 🙂
