Making of a mug: Day eleven

Part one

 

Part two
After dipping the mug was set aside to dry for a while. I check each piece thoroughly before putting it in the kiln. Often there are a few drips that need scraping off carefully with a knife (fettling). The bases are also given a final check and wiped if any glaze has stuck to the wax.

Part three
Once again the mug is put into the kiln, this time for its glaze firing. With the biscuit firing it doesn’t matter if pieces touch each other, but with this firing it is very important that the mug has space around it. The mug will expand considerably as it heats up, and then shrink as it cools. If pieces are too close the glaze will cause them to stick together.

Part four
Normally I would leave the mug overnight to dry before firing, but I’m trying to get the firing completed for the North East Open Studios (NEOS) which start on Saturday. To help dry it thoroughly I have added a preheat to the firing cycle. The mug will then be fired to cone 7 (1239˚c). This will take roughly 14 hours to reach temperature and once again a similar amount of time to cool. I hope to be able to open the kiln tomorrow night…
