Now that I have a kiln that can fire to cone 8, I can finally experiment with colored porcelain and Nerikomi on my own schedule without having to wait forever to see how a pot comes out. I am using mason stains to color 257 porcelain which I bisque fire at Fleisher Art Memorial, and then fire it a second time at home, unglazed, to cone 6 . This porcelain was made to be fired to cone 8-10, but it gives very nice results at cone 6 which is how they fire it at The Clay Studio where I first started using it. I only take my kiln to cone 6 to preserve the firing elements. I’m learning as I go by watching videos and reading what I can on the Internet. Most of the books on the subject cost a small fortune and I haven’t found any in my local library. No matter. I’m having fun and that’s the only thing that counts.
When the bowl gets leather hard, I will smooth it with a metal rib. It is extremely fragile when it’s bone dry, so I try to do most of the work at the leather hard stage. After it’s bisque fired, I’ll sand it with wet/dry sandpaper and then fire to cone 6. After that? I plan to experiment with paste wax. This will be a decorative bowl.
