real copper look finish on pottery? anyone?

M Pepper on wed 23 feb 05


I am a novice potter and have surfed the internet and
other resources trying to locate the glaze that makes
pieces look as though they were welded of real copper
plating rather than a glaze.I was wondering through
New Orleans Louisiana and happened on a shop that
carried the Potter's craft.Almost all of it had a
copper introduced into it.This copper looks just like
the same bright shiney copper metal pots or bright
copper pennies. I was very curious about the glaze and
wanted to ask the shop owner but felt that he may not
want to give out that ,if in fact it was a
secret...Therefore Im still wondering.. Can anyone
give me help with this question.. I really love the
glaze of effect of whatever it is..Any info on it
would be greatly appreciated...Michael

Micheal, there is no way for me to be sure but the pots you saw were
probably raku. If you want a bright copper penny type of shine all you
need to do is use a glossy raku glaze with Copper Carbonate in it. Just
go into post firing reduction very quickly and make sure that your can
seals well. A coupla sheets of moist newspaper draped across the top of
the can befor closing the lid works great for a nice tight seal.
There are a great many glossy glazes for raku.The one that I use to
get the bright shiny copper look that I think you are after is , by
weight, 65% Gerstley Borate, 15% Neph Sye, 5% Tenn Ball Clay,5% Flint,3%
Tin Oxide, 3% Zircopax, 3% Copper Carbonate. If the glaze is oxidized it
will grow a bright green color. You need to remember to get into post
firing reduction very quickly if you want the copper penny look all over.
I don't remember where I picked up the glaze from, otherwise I would
attribute it to it's author. Chances are it either came from Robert
Pipenburg, Steve Branfman or either Linda or Sheldon Ganstrom. I've been
using it for at least 10 years.
The glaze is not a stable one and is not meant to be used in any
way, shape or form for functional (food service) purposes. It will fade
with time, require occassional polishing, is photo reactive, and, once
again for emphasis, is meant to be used for decorative purposes only.
For a definitive explanation of raku glazes and what happens to them
over time visit the digital fire websight and read Tom Bucks article(s).
He is dead on with what he has to say. There are also alternative glazes
to the older ones that are far more stable that you may want to try out.
Here's the link to the site and the article and suggested altenatives

Hope this helps

Any time I see a glaze or technique that I really admire and catches my
attention, I ask about it. I would have to say that at least 99% of the time
the potter is willing to give me information on the subject. If they start
to stray away from the question, then I need to respect that. We potters, I
find, are friendly people who love to talk about our works. Next time this
happens, strike up a conversation and let the potter know that you really
admire his work. I think you'll find that in most cases the potter is
willing to be helpful. I've learned over the years if you don't ask you
won't know. I personally don't know of such a glaze but maybe someone out
there does and will be willing to share it with you. What's so intriguing
about this medium is that there is always so much to learn. Have fun with
it. Donna

One of the ways people get that affect is with copper in reduction on raku.
I don't have the formula, but you need to ask yourself, what happens to a
shiny new penny over time?

That may be one way to do it, however there must be others.

Take a look at Figure 4 on this page...

The page is in Japanese, but that particular work is quite unusual in=20

enamels on porcelain, as that would be typical of Tomomoto's work.

Wes,

Thanks, I suspected it was raku but would give
anything to know what he used when doing this if the
process was in fact raku. If anyone has any ideas
please let me know.I will try to find some of his
pieces on the internet ..."perhaps" if I can and maybe
be able to send you a few and anyone else that would
possibly have any ideas..Thanks for replying and
anything that anyone else could contribute on this
would be greatly appreciated..Thanks, Michael

Donna,

I suppose you are right...I have always made of
habit of asking others ..always without exception..and
maybe to the point of irritation to a few.. without
really wanting to be ..I was in this person's shop and
overheard a conversation that was directed at someone
asking a few too many questions and the person was
rebuked for it..so ...I didn't feel that I might want
to stand in line to be next hehehe...so you can
imagine..and yes I respected THAT..hehehe so much that
I didn't ask ..where I normally would.. All artist
myself included usually don't mind people asking
questions.. I would seldom refuse anyone asking to
learn anything... but then again..there have been very
few secret things in my life that I felt needed
protecting..Im also smiling again...Donna, I really
appreciate your input but once again I have thought
about it and on this particular person..."maybe
not":-) By the way.. once new a Tony Nicosia.. any
relation? ....Thanks..Michael

MICHAEL,
If you received negative vibes from the person then I guess it would
have been fruitless to pursue the subject. Anyway, there are a few Tony's'
in the family. Where from? Donna
