Hi! Go to www.digitalfire.com and look up Tom Buck's article on no-fade
raku glazes. He explains a huge amount of information and gives sample
glazes. A wonderful read if you're into that sort of thing! ;)

In Colorado still smelling like raku smoke from my class tonight...

Hey everybody, I didn't get any bites on my problem of how to alter a Raku
glaze so that it doesn't become muddy in 5 years--the glazes with copper.
Thanks, Carolyn

Paul Gerhold is wrong when he states my raku glazes do not work -- many
potters since 1996 have said nice things about the glaze recipes there.
raku process is not easy to control if you vary glaze coat, duration in
kiln, time in bucket, type of material in the bucket. raku firings need
consistency.

Try this web site, it has lots of interesting info on raku stability.

Carolyn,
Go to the DigitalFire web site and read the article "Now you see it now you
don't".He has some ideas on solving the problem with the caveat that his
ideas are untested. If his great ideas are like many of mine they probably
won't work but will give you a starting point.
Other people have talked about sealing the glaze with a clear acrylic spray
which probably will work for a short time. In my opinon this is a way
underfired glaze that won't hold up over time no matter what you do to it so
putting it on pots is probably ethically questionable at best.

I have a related question. With an in-glaze luster (such as that on Beatrice
Woods' pots) the luster doesn't fade with age. Is this because: The
glaze,which is similar to a Raku glaze' is reduced at a higher temperature
;or over a longer period of time? Or maybe because there is more silica in
the glaze?

Bob H:
there are different lustres - oil (resin) lustres for use at Cone
022 with no reduction involved, the colour components are built-in and are
stable. There is a book available that explains these types.
and then there are Raku lustres - copper compounds produce either
reds or bright penny, suitably combined with other components; silver and
bismuth compounds produce mother-of-pearl and gold; and other materials
produce the matts (eg, cobalt/phosphorus "coppersand", "alligator" and
"rainbow"). the Raku lustres require consistent firings/reductions.
