For the past 2 months I have worked at Wheaton Arts, in Millville NJ. In their old glass factory are highly skilled glass artisans and artists making various things, some for other artists. I was invited to be a Visiting Artist there and learn how to paint with enamel. Skitch Manion there has blown about 35 cylinders for me and I have been painting them. The piece have to be fired to make the paint melt and bond with the glass. Some pieces may take only one firing while others need 3 or 4 or 5.
