I hadn’t planned on posting on here today, but the weather is less than great, canceling both my roofing plans and my barrel firing plans, so… This morning I did get to unload the glaze firing I did yesterday. I have been having some problems with firing my kiln to cone 6, so this was kind of a test firing.
I never really realized how small my kiln is. I got done unloading and thought, “Wow, there was hardly anything in there!” I knew my kiln wasn’t huge, but man, it is small! Now I’m always going to be self conscious about my kiln size. Actually, between the realization about my limited kiln space and its recent chicanery with glaze firings, this would be a good time to look into hooking up my “new” kiln. (My wife’s cousin recently moved and gave me all of his old pottery equipment, including a kiln and wheel!)
So here are the results. There were a couple of grow pots (planters), some tea bowls, a few mugs and a number of glaze tests. I was fairly pleased with how everything turned out, especially the toasty color of the clear glaze over the tea bowls. The color doesn’t come through too well in this picture, but it is nice…or at least I think so. I still have to go through all the glaze tests, but I think they will yield some good information.
This is one of the mugs that I have been working on. It has a light underglaze wash and clear glaze on it. I have a few more that are textured like this, but I am not sure about finishing them the same way. Would a colored glaze be better? Do I need to do something with the handle? I don’t know. Any comments or suggestions would be more than welcome on this.
And finally, the over firing issue. This load was over fired, but only slightly this time. I set up a witness cone so as I could keep an eye on it throughout the firing, but apparently I didn't watch it quite close enough. After running through the firing schedule for about seven hours the automatic shut off had not dropped on the kiln sitter, but the witness cone was bent so I turned it off. When I unloaded this morning some of the work was slightly warped, but not terribly so. And then there was this…
You can see that the cone is bent slightly more than it should be (at least I think it is), but the bar for the kiln sitter is hardly bent at all! What?! So the question; is there a problem with the kiln sitter or did I somehow get a bad batch of bars? Both puzzling and frustrating.
