This is what happens when you get a torrential downpour while the kilns are being lit! These are brands or browns, and are a result of the temperature being too low to create charcoal. We had a biblical downpour (ok, maybe a slight exaggeration. But only slight!) the last time the kilns were lit. The rain creeps into the kiln and dowses the growing fire. The rain also made its way through everything I was wearing. I was saturated!
This here is about 2/3 of the wood that went into the kiln! Luckily the other kilns were much less affected.
