No Promises

I'm trying to load the video via Camino instead of Safari....
Yes! Persistence,that vital [some would say the only] requirement of the potter,pays off.
For the technically-minded,this bowl is thrown using 480gr. clay- what Bernard Leach called a GP bowl [General Purpose].
Kiln # 17: just when you feel you might be getting towards some sort of feeling for these glazes,your kiln elements start to perish- this firing took 7 1/2 hours to top temp,up from 4 1/2 for the first few. This,of course,affects the way the glaze behaves in parameters not indicated by even the all-knowing pyrometric cone- for instance,the longer the glaze is in a molten state [say,the last 200 degrees] the less material is available for growing the crystals...
Let's say I manage to squeeze another 3 firings out of this set of elements. Replacements will set me back close to $200- which means $10 a firing,or $2 a pot.
Glodie,Reuven and Naomi [new daughter] have just arrived for a visit,so bye for now...
