This is what I have been doing over break. Freaking test tiles. I got a kiln and a boat load of enamel and have been soooooo excited to actually use it/some. Of course we have to get the formalities over with first. These are just the opaque enamels. Now it is on to the transparent enamels. Some of the enamels are old and not firing properly. They are kind of old. Also we just found out something about the cat. If you put something on the her head she freezes up, hence the cat coaster.
