Hi Melinda----- Historically there has been a lot of work done at cone1-3,
actually right up to the 1950's when we had the big cone 10 reduction
revolution. If you can get your hands on reference texts that were written
in the 20's and 30's, particularly the Abstracts from the Journal of the
American Ceramic Society, you will find it chock full of info on this
temperature range.
I've got to concur with John Hesselberth on the ability to develop
glazes that some potters say can't be done at lower temperatures. During the
last 'energy crisis' here in California in the 70's, I helped to develop a
line of Cone 06 reduction celadons, tenmokus and copper reds. The Idea
being, 'Why waste energy going to Cone Ten ?'. Well the 'energy crisis'
petered out, so did the clamor to drop down in temperature and the
manufacturer lost interest. Here it is 30 years later and a large portion of
Studio work is still done at cone ten.
John's right about this part too, if the demand is not there from the
potters, then it's not produced commercially. That's the only reason there
is no wide spread availability of clays and glazes at cone 1-3.
