Antony:
Purples & violet glazes:- American Ferro Frit 3110 (Aus Ferro Frit
4110) is OK for copper & manganese blue development . You may have some
crackle/crazing with that. Look for a high alkaline content for blue
development. The old Egyptians & Persians used their natural sodium sands to
develop their beautiful blues. Here are a couple of oldies.
These fire at 1250-1280(cones 8-9)in oxidation & should be OK in light reduction
PURPLE
Potash feldspar 40
Whiting 5
Dolomite 20
Mag.Carb 10
Ball clay 15
Silica/Flint 10
add 2-3% cobalt carb up to 8%
(the mag. carb & the mag.carb content of the dolomite help in developing the
purple/mauves.)
------------------------
BLUE
Potash Feldspar 70
Whiting 20
Ball clay 10
add .5% Cobalt carb
2% copper carb
---------------------
or add 3% - 6% Rutile
3% copper carb.
.5% cobalt carb.
----------------------------------
If you wish to lower the firing temp. by a couple of cones try an addition
of 10%-20% of the frit.
Happy firing. Liz Mount.

Hi!
Why not just use stains as a start? Mason, Cedric/DeGussa, Spectrum,
ect. all make colors in that range. Most pinks/purples are chrome-tin
based and need to be in a base with at least 12 percent calcium, some do
better without zinc. And, there's nothing wrong with blending stains of
different brands, stains and oxides, ect. Since your working at lowfire
range, you don't have to worry about color burn-out. You can get small
test samples of stains relatively cheaply from most suppliers. Make a
lot of tests and have fun!

Joy,
Try the Red, Purple, Pink, Mauve. I am just starting to play with it, and
apply one thick coat. The color goes from a dark burgundy where a bit
thinner, to flecks of violet blue where it pools. E-mail me privately if
you can't find the recipe in the archives.

Hello,

Purple Chun. The other is Heino Purple. Both are cone 10. I would
appreciate any help.

Hope this is the one you're looking for. There are a lot of purple chuns
recipes around. Check the archives. I'm pretty sure you will find some purple
chuns in there. If memory serves me, I've posted a couple in the past.

Thanks to everyone who offered me purple (and purple/orange) glaze
ideas. I'm going to mix some test batches and I'll report back on
what happens.
Peace!
