Bisque Firing

This bisque firing went OK. I had two pots break because I was too impatient with the drying process on a few pots. I figured a day to dry and then a full night with a box fan on top of the kiln was sufficient to remove the moisture. Only one real loss though with an orb pot that I made.

The clear crackle raku glaze at cone 04 was VERY interesting with some bubbles being trapped. There was no crazing that I saw on the Raven clay. I am thinking about doing a pot in raven slip, firing it to cone 6 and then re-firing to cone 04 with the raku glaze. I’m contacting the manufacturer to see if it would be food safe as long as there is no crazing. Almost a frozen root beer effect with a lot of depth. Not sure how it will turn out on a cone 6 fired body and then re-firing but we shall see.

Surprisingly on the raku clay there was a bit of crazing.

And here they are all together.  The red clay body took the glaze very nicely and there was no crazing at all, just a deep clear glossy finish over a terracotta color.

Only one of the batches of processed clay kind of held up cone 04 firing, and that was batch 01. It makes a nice slip too so far. I really still want to fire the rest of these to cone 6 just to see what it will do. Some of the flakes of minerals in the sandy clay would make an almost glittery surface if they were to adhere to the surface of a vessel. Experimenting is fun!
