Well, more like demolition debris. I had a plan to invite all the strong guys I know to come and help take apart the kiln; in fact that was set for June 5. But my brother-in-law, visiting from Massachusetts, had a better idea: just bust it up. Since I had already decided I was not planning to re-use the arch, I should have thought of that myself. So he grabbed his two-pound sledge and we went to work.
There were some salvagable brick in the walls -- not that I expect to need them, but it's better to have too many. The rest could, I suppose be ground up to make castable -- any takers?
