firing reds

for sure, you do not need an oxyprobe.

we do not use the oxy at the farm, four kilns and
always get red.

the secret is:
good reduction.
slow cool.

it seems that there is a point at about 1700 that
red turns from green/white to red.

if you rush through that point, it does not change.

that is why if you are doing a great deal of red, it is good
to re/lite your kiln for a bit at that point...1700-1900F and
make sure the glaze goes through two cooling cycles.
fool proof.

once you start to get red/ understand that it is the firing and the
cooling, they just happen all the time.

one of the most admired of glazes among the historic japanese potters
was red streaked white. it was called `sheen shaa`
it was the result of flames licking copper based glazes and
then the slow cool of the big anangamas. sometimes you would
get a half pot bright red, sometimes the outside was red/inside
cream white. the multi-streaked ones were a delight.

many western potters think that these are mis/made reds...and
throw them out. `hey, wally, these streakie ones do not look like a coleman
ad for geil kilns, throw them out`!

firing a kiln full of red as the ad shows is rather easy. in fact, if you
follow the re/fire technique it will happen every time.

if you follow some simple rules, red is as easy and boring to get
as white glazed porcelain.

Well Mel,

"any western potters think that these are mis/made reds...and
throw them out. `hey, wally, these streakie ones do not look like a coleman
ad for geil kilns, throw them out`!

mel"

in the old days before echography pregnant wome often said
"I will take whatever God will give me", when asked wether they
prefered a baby boy or a baby girl. I do exactly the same when I
fire my kiln, a little surprise is always very interesting.
