I purchased a beautiful already glazed and painted white, one piece ceramic round Nativity,(it has six (Mary, Joseph, the Three Wise Men and a cradle) placed around a circle and I would like to paint a different color. Now it is all white, and I was not thinking of painting each individual figure, but rather having it an opalesque color with or without glitter. The problem I'm running into is that everyone is telling me that the paint will not hold unless I have it baked on. Is there any kind of paint out there that will stick on this piece without having to heat it again?
