I have been having bad results with my raku firings lately. My copper
sand glaze is getting too shiny. I fire to ^06-05. I want a nice soft
reduced look with a lot of color. I do not have a ball mill. Does anyone
have a good glaze or a firing technique that I could try? My glaze
contains bone ash, gersley borate, red copper oxide and zircopax. I
have been using the same glaze and firing techniques for years and need
a change.

To Ilene, George, and everyone,
With all due respect and desire to offer help and advice, a posting like this
one is a true shot in the dark. More details about the "problem" need to be
stated. What constitutes "bad" results? Are you asking why your present glaze
is firing too shiny? If so, some possible answers could be given. For
instance, you are likely firing too high. There are also different ways to
achieve a "softer reduced look with lots of color". For instance, one's
method of post firing reduction has a major affect on color. "Does anyone
have a good glaze or a firing technique that I could try?" Are you looking to
develop a new palette of glazes? If so, there are a zillion different "raku"
glazes out there as well as many different firing techniques. Are you looking
for immediate satisfaction with foolproof glazes and methods that will give
you exactly what you're looking for the first time? Um..........
I don't want to appear to be difficult and absolutely no disrespect towards,
or pre-judgement of Ilene and George, but I think alot of postings and
questions go unanswered or not adequately answered becaue the questions are
too vague and sometimes appear to be looking for quick foolproof answers that
need no effort on the part of the questioner! Getting satisfactory results
takes alot of work, experimentation, and effort. I love to share my
techniques, glazes, clays, knowledge, and experience but I want to know that
the recipient is doing some work to get it? I don't know if this is coming
across the way I mean it but what the heck..........I know that the group
will get back to me!
Talk to me.......

I'm no pro, but here are the experiences I have had . . .
When we have pulled just a little earlier than the full cone, the results
have been more matt. Seems that by eyeballing and getting a feel for just
when the glaze has fluxed is when results have been the best. Try some
experiments pulling pieces a bit early.
Good luck

Ilene:
You might want to try this recipe for Red Bronze:
Gerstley Borate: 50 grams
Frit 3134: 50 Grams
Tin Oxide: 5.1%
Copper Oxide: 4.3%
This has given me excellent results; try it and see how it works for
you.

Ilene,
Is it possible you are not thining with enough water?? I use only
a patina recipe to get both matt and shiny glazes. By not adding
as much water to the mix, it makes the patina a gloss glaze. This
way, I have to use less glazes in my studio.

Try firing to cone 08. You are firing too hot for a matte-sand look.
When you fire to 06-05 you will get a gloss. The bone ash is intended to
create a matte look at the lower temp. The colors are achieved during the
reduction not the firing. Without knowing the recipe percents I cannot
tell if you have a good chance for colors. You might first try to lower
your firing. Good luck. Here is a good recipe:
Hines Patina
7 parts Gerstley Bor.
3 parts Bone Ash
2 parts Neph. Syenite
1 part Cornwall Stone
1 part Copper Carb.

Steve,
I have been potting for ten years but have only been a Clayart subscriber for
about six weeks. In that short time I have seen any number of requests that
seem to fall in this category and probably are best answered by referring the
requester to a good book on the topic of concern. I don't think there is any
substitute for a small collection of good books. There is probably another
element working here, that is, the more we know, the more we realize how
little we know. In the beginning, it isn't always obvious how much you are
asking for.
