While at Bullseye last week for the class I took, we were shown how to properly prepare a kiln shelf for firing. I’ve been an advocate for thin fire to fire glass on, but that’s because I can be a bit lazy now and then. You can get away with it for flat work but if you plan to slump your work you’ve got to use kiln wash to prep your surfaces. Over at the Warm Glass web site they have a tutorial on how to coat your shelf with wash. The picture in the pdf file was taken at Bullseye, so this is exactly what I learned last week. I’ve been shown this procedure in the past but Nathan, our fab instructor, was so good he made me want to always use kiln wash. And since I did pick up that set of square plate molds in various sizes…but that a whole other posting.
