Do you watch Alton Brown? When he talks about gadgets he only likes multi-taskers. I like that. So, when I do a bisque fire, the first of two or more trips to the kiln a piece recieves, I like to also have some glazed pieces getting re-fired. This firing is to about 1825-1850 degrees F, so low fire is a relative term. If you were cooking your thanksgiving turkey to that temp, you can be sure it would be a dry turkey! When I fire my clay to maturity, usually cone 6, that is up to 2260-2290 F. If you peek into the kiln with protective glasses you can watch as the color changes from black (shadowed no heat) to cherry red to lollypop orange to bright yellow, and if you are high firing you get to white heat and then the pots ( or beads) almost look transparent and shimmery.
I once fired a sculpture of an angel for someone, and her face was looking right at the peep-hole of the kiln. It was disconcerting to say the least to peek in at this angel that went from black to red to shimmer, and she was looking back out at me :-)
Anyway, this morning I am prepping for a low fire, so I have some new pieces drying out,
and some pieces that have been glaze fired at ^6 and touched up with ^06 glaze going back for another glaze fire,
and some "kiln mice" being bisqued. What the heck are "kiln mice"?
are little chunks of clay that stand upright and have a texture so you can use them to test and document glazes. I used my little homemade star mold to put a star on each, poked a hole in them, just like for a charm, but they have flat bottoms so they do not have to be hung up to glaze fire. I can place them all around the kiln anywhere there is a little space.
So I will bisque them as soon as they are bone dry, then put test glazes on them along with identifying text that I will paint on with a brush and stain. Tedious, but the best way to test that I have found. Eventually you end up with an army of little clay kiln mice all over the studio. Something for the studio helpers to play with, lol
