i want to follow carols post about iron glazes.
the amount of reduction, and how you cool
has amazing influence on iron reds, temmoku and
such.
it takes time and experimentation to get great
iron glazes.
i find that many mix every glaze on the earth
in every firing. many glazes need special attention.
so...saying that...when i fire copper red i do a great
deal of copper red at one time. when i do rhodes 32, i fill the kiln
with it. same for a set of dishes with temmoku.
the coleman ad for geil is a perfect example...it is much
easier to do the entire kiln for red than ten pots mixed in
a mixed firing.
in fact, i have been preaching for years that many folks
over reduce. black smoke, gobs of back fire from the ports
and very metallic glazes result.
that again was a 50's idea. cone ten, heavy reduction with
no idea `why?`...just, `that is the way we do it`.
so many of the techniques with fuel kilns are just fuel wasters.
and, that leads to very expensive firings, all from your wallet, and
not so good glazes.
again, as we preach. ` fire for fuel saving, down fire for affect and color=
,
and fire to cone as fast as you can with the greatest use of air/ fuel, the=
n
get wondrous affects in the cooling cycle.` (you can down fire with one
burner, 1/4 gas, and hold the temp. economy of firing for sure.)
