cnc in colder upstate N.Y. You want cold? We've got it here.

this will not give you a red..... your "mix" may be the key,... does it
contain silicon carbide/ If so it might work in electric firings. If you want
to.. email me directly and well talk about making this work..

I've never tried copper reds in electric, but the idea has always intrigued
me. My understanding was that they needed to contain granular silicon carbide
or something that would create localized reduction.
Many moons ago I got hold of some silicon carbide tape intending to wrap a pot
and see if I could create red patterns that way. If I ever start firing cone
10 electric again I'll try it. If anyone else has ever done this--how did it
work?
Undoubtedly someone out there knows more than I on the subject, but here's my
two cents in case you don't get any better.

Last year or so Ceramics Monthly had an article about Copper Reds in Oxidation.
My class tested all the recipes, purchased the silicon carbide and special frits
from a company in Ohio (I think). Our results were just what Craig Martell
said--too fluid on vertical surfaces. Wish I'd just e-mailed Craig and asked!
But it was fun and educational! The Chrome Red ^6 Oxidation glaze in Lana
Wilson's book is the best I've found. Good Luck.

Here is a glaze that I experimented with some time ago. It's a pale green with
many red speckles. It also crazes.
Cone 4 electric
Nephyline Syanite 32
Gerstly Borate 14
Strontium 26
Silica 30
Copper Carb 2
Silicon Carb (fine particle size) 1.5
Tin 1.5
Ball mill the copper, silicon carb, and tin then add to the rest of the glaze.

last spring i was living in berlin and visited a potter's shop. she had some
tiles with lovely red splotches. she also had quite a few bowls, cups, teapots,
etc with this plum red color. the other colors she liked were very shiny
greens and blues. when i asked her about her red glaze she said she used
"graphite". i also went into her studio and saw her kiln. it was front load
electric and she fired to 1250 cent. i have since seen mentioned in two books,
both published in the uk,just two sentences referring to german potters using
graphite to achieve reduction in an electric kiln!
does anyone know any more about this? i bought a batch of her tiles and took
pictures of her pots on display, but can't crack the "graphite" problem. any
ideas, suggestions.
TIA

My second message on the subject only to say:
You haven't gotten much encouragement. In the late 70's early 80's there was
a woman potter doing the art fair circuit in Minnesota who was locally famous
for her electric fired copper red. It did occasionally "flash" white but
always looked good.
At the time I thought she was "cheating" but now I can admit that after
beating myself up for a whole semester at the U of M in search of the perfect
copper red I was secretly jealous. It was a very lovely and dependable glaze.
Sorry I can't be more specific but just wanted you to know it can and has been
done well.
