While in the U.K. this summer I took Mike Bailey's Stoneware Glaze Course at
Bath Pottery Supplies. It was sensational and I came away with a much better
understanding of glaze chemistry and "The Eutectic Point". One unexpected
revelation, although I had some less dramatic experience along this line,
was the totally different results of the same glazes on the twenty or so
varyious clay bodies tested, ranging from a glassy celadon on one to a toast
coloured lava-like foam on another!

I wonder what eexperience others may have had along this line.

I remember a dark red clay body that was wonderful to throw with and thus to
teach with until we discovered that it killed the life in all our glazes!

I spent the summer testing out several different clay bodies in
anticipation of changing suppliers and needing to make a large order (up
here in the north country we don't like clay delivered frozen!). After
narrowing down to 3 the bodies I liked, I made test tiles of each and tried
all my glazes on them in my electric kiln. Oh, my, goodness gracious, what
a learning experience! Two bodies actually improved some of the glazes,
making them brighter and smoother. The 3rd body drabbed everything down
awfully, except for one gem, which looked like it had been reduction fired.
Then, I tried that ugly 3rd body in reduction, and the results were far
different from the oxydation ones! As I write this I realize I've got to
do tests of the other 2 bodies in reduction. Oh, the endless work and
discovery of clay! Ain't it wonderful?!

Corinne, in gorgeous so. nh, where 3 cities (town sized to the rest of you)
are the best to live places in the usa!
