|OM 4 Ball Clay||12.00|
F-4 feldspar is no longer available, so use Minspar 200. This recipe was graciously shared with me by Ryan MacDonnell, ceramics professor at Montgomery College. It produces flashing effects in wood, salt, and soda firings. I have also found that it yields a salt-like effect when used under my Basic Wood Ash Wash. Apply to leather-hard clay.
