Ceramics class was my favorite, and was right after lunch. Our teacher would open up the room during lunch, and I'd be elbow deep in clay most days. Ahhh, blisssssss, two full hours of nothing but clay. He let me get into the "secret stash" of oddball supplies, like powdered cobalt, iron oxide, red clay, and discontinued glazes. I found stuff he never knew existed, like the clear glaze. Woo hoo! BTW, if you ever get a chance, put a layer of cobalt under a layer of white glaze. Prepare for blue-mazing color!
