Hi Paul:
I have R&J's book - I sent them a cheque prior to the printing!!
The "red" they have in the book is a chrome/tin glaze. I've fired it =
fast, slow etc. and it remains a lovely raspberry colour. Fired fast, =
the glaze is glossy; fired slow, it is semi-matt.
Copper red in ^6 electric? Not that I've heard of yet....
take care
sam - still enjoying your mug in melbourne.

I heard, I think I tried (out of 1000 tests?) and failed. I think it
has the same idea of tin chrome Isn't it? The tin paints the copper or
the chrome.
When I worked with my old kiln. I made a dish with the majolica, the
rims I made with a green decorative glaze of Duncan. The majolica
glaze became pink.
To that old in it's last days took 20 hours to reach 1000C.
My good friend Yehuda Koren told me once you could put in a dish below
tin glazed ware either chrome or copper. the fumes are painting and
make red spots.

Dear Sam
Thanks for the info I will get R/J book. Over here some potters have
made reds with silicon carbide as a reducing agent to use in an electric
kiln . I presumed wrongly that Ron had worked out a way of making this sort
of glaze a reliable one. However every thing I said still stands even for a
chrome pink; although no reducing agent is needed and the color is more
reliable. As you say the texture is set by the cooling and temperature
relationship.
I know of no one in Europe who firs to cone six and there is not the range
of clays that fire especially to that cone for sale . I expect the clay
companies expect their cone 8 stone wares to do. I will try some since I
fire some of my glazes near the temperature. about 1200 c or a little above.
I have discovered how they make glazes for painting: about 4% glaze hardener
in a finely ground glaze so I can make a larger range of glazes for my
students to try since you do not have to mix as much for painting.
Your mug arrived my wife immediately confiscated it to drink her
cappuccino out of . Nice size sensible handle was her comment.
I liked it and it will be used along with the other mug I received from
Longknife two years ago - to make a collection of the years in clayart.
again thanks
