Yellow/green discoloration on kiln shelf from flooding

Recommended Posts

A while back I had some very minor flooding in our basement. Two kiln shelves were leaning against the wall with the bottom edge sitting in maybe 1/2” (or less) of water - and this yellow/green discoloration appeared. Has anyone else had this happen? Not sure if it was something in the kiln wash that reacted or what- but I’ve been hesitant to use them in a firing. Any thoughts would be greatly appreciated! Thanks! B5F3920A-BE41-48D9-BC6F-FC35975F28AD.jpeg.58efbe3c6a57d44e04d490bfad033051.jpeg

I'd go ahead and fire them off once without pots to bisque temps just to be safe. Chances are it won't be a big deal, but better to do them without pots on them just in case something weird happens. I think the worst you'll see is that they gloss up slightly, but chances are there aren't enough salts there for that to happen. If any of the color is actually organic matter it will burn out.
