I was not in the workroom. I heard a strange noise, but given the wind, figured it was outside. I was waiting for the kiln to heat up. I did all the prep work for the enameling final steps. I went to open the kiln, and the kiln door did not want to open. The strange noise had been the sound of one of the two kiln door springs breaking off. Damn!
Not a long term problem, just not fixable on MLK Day. I need to remove the broken spring and go to a real hardware store(tm), probably Winks, to get a replacement. Tomorrow.
