I just bought a collection of ceramic pieces, green ware, bisque, partly painted or choked, from a former ceramic painting teacher. Most of the pieces are from the late 80's to early 2000's. I'm trying to find out how to fix some of these pieces, such as broken antlers or wings, legs or feet or arms or hands. Some of these pieces have been started painting or choked, some are green and some have been fired ready for painting or choking. How do I fix these pieces if I'm going to glaze them then fire them again? How do I fix the green ware so I can fire it? What is the best way to fix the pieces that I'm not going to refire?
