So I just opened kiln load no.1 for my show this weekend, (Potters Market Invitational) I'll put up some more info on that later, and everything looks great!
S normally on my jars the lids stick a little bit and I have to tap them to get the lids off (sometimes with a 2x4). Needless to say that is not ideal so I tried something new, to me at least. I mixed in some Alumina Hydrate with my wax and put it on the rim of the jar where it comes in contact with the lid. The lid came right off, and I wiped the leftover alumina right off! Why have I been beating up my pots so much? Why haven't I been doing this sooner? I know this is not news to some of you but I'm just so excited. Just need to be a little careful about how liberally it is applied, it can affect the way some surfaces appear keeping them from fluxing.
Random thought and question... Do you think doing this would work in a salt firing instead of wadding in between the rim/lid?
