Not so great of a weekend here. Well, the weekend was ok, but one event put a grumpy cloud over it anyway. I had a kiln misfire and the contents were way over fired. It is several days worth of work lost, as the items are pretty much destroyed and unusable.
Above is a picture of some of the contents. This was a bisque kiln, so it was only intended to go to about cone 04 (about 1900 F) But something happened with the cone (I think one of the cookie ornaments exploded and made the kilnsitter stick) and the kiln never shut off on its own. Today I am regretting not having a timer on my kiln, and also being careless in not manually checking that the kiln shut off when I knew it should have. I went to bed with it on...bad!
So anyway, in the picture above you can see one of the terra cotta bowls that I fire my bisque in on the left. And in the center, there is the same type of bowl after the misfire. It is totally an oozy melted mess, and that shelf is probably ruined. There was also a second bowl full of beads that is ruined too. Also you can see the cookie ornaments, one the way it is supposed to look, and the others overfired. This kiln must have gotten to over 2200 F, I would guess.
The porcelain beads are vitrified and while they didn't stick together like the terra cotta did, I don't think I can really use them for anything. I should really find something to do with them, they are very sturdy actually, just all white and matte. It is too hard to try to glaze them, as the glaze doesn't like to stick to vitrified clay...I have tried in the past. Any suggestions? Paint? sigh
Now I have to buckle down to catch up and redo everything that was lost. So that is my tale of weekend woe and burnt cookies. One of the sad days in the life of a ceramic artist...
