[Sca-cooks] cone temps was: pottery braziers, cooking in pottery

[Louise Smithson]

Katherine asked: Might you explain the difference in "cone" in terms of 
temperatures please?

Cone 05 1888-1911 F, Cone 04 1945-1971
Cone 5 2167-2205 Cone 6 2232-2269

It may not really look like much, really only 200-300 degree difference, but it 
makes a huge difference in the way that the final pot behaves. 

It's easier to see rather than describe.  If you know any potters ask them to 
show you a bisque piece and a high fired piece of the same clay.
