Has anyone used a raku kiln to test cone 10 glazes??? Will it work and =
give a general idea of the color??? What would be the problem with =
firing a piece to cone 10 and letting it cool in the raku kiln, not =
pulling it out as you would raku???
I know my kiln will reach cone 10 because it got away from me one day =
when I wasn't paying attention.

Probably the biggest difference wil be the
faster cooling time. Even if you don't yank
it out, raku-style, it will still cool much,
much faster than most normal ^10 kilns. So,
you could do this, but the results will look
different in your other kiln. Most likely,
your raku-kiln tests will be shinier if they
were meant to be matte, and have less texture
and mottled color than their conventionally-
fired versions. You could 'fire down' to
give a controlled cooling, but if you do that,
you might as well just use the other kiln.
You'll always get the most useful tests from
samples fired with other work, in the same
kiln with the same conditions it will
eventually encounter in real use.
