Hi! I have a very small (tiny) electric kiln which I fire up to cone 04. Currently, I have been bisque firing terracotta and earthenware up to 1100C -1150C then glaze firing to 1060C - as the low fire glazes I have say to only go up to this temp. Results have been pretty good so far. I am aware of the dangers of single-firing (with glaze bubbling, pin holes etc) but now I am wondering if it might be possible to fire both bisque AND glaze together in the one firing - say up to 1060-1080C? What would be the down-side of doing this provided I brought the temperature up to 600C very slowly?
I really love your forums - and am very grateful to all the wonderfully generous potters, who so freely share their experience and advice!
