Meet "Spike" (Shaw's boxfish jar)

Shaw's Boxfish, 12 inches long. Various Laguna and Coyote glazes (a real mish-mash).

Mmmmmwah!

Spike's lid is a very tight, precise fit. Ordinarily I would fire the lid separately so as to have more glazed surface. In this case, I fired the jar and lid together even though there was a risk the lid would stick. It seemed preferable to the lid not fitting at all.

Upon removal from the kiln, Spike's lid was indeed stuck, but not fused. I tried heating and cooling the piece to see if the clay would expand or contract enough to allow the lid to come off. I could feel an infinitesimal amount of give... Finally, with the help of a bread knife, the lid popped right out. Hooray!
