Now here's a weird one for you.
A few weeks ago, I broke off a gold crown and saved the thing. Dentist
said, "Why not put it in a pot?"
Now that is a heck of an idea. Ought to make a highly personal decorational
statement!
Problem is, there is no room for "test, test, test". It is a one time shot.
I don't normally fool around making statements with gold.
Hamer is no help for once.
Maybe a small porcelain bottle with a gold splash? ^6? ^10? Or does that
matter?
Or a nicely burnished tea-bowl with no glaze? White micaceous clay!
What kind of glaze wouldn't be over-kill with an accent like that?
It's the kind of dilemma that makes strong men weep.

Take one filing,
Weight it, dissolve it in Aqua Regia,
Figure out the concentration.
Get a recipe for a glaze and use it.
That is my suggestion.
Here is a recipe. The frit may be leaded. I have never used it.
Glaze name: Transparent Alkaline With Colorants
Cone: 014
Recipe: Percent Batch
Lithium Carbonate 10.00
Ferro 3269 43.40
Pemco 54 26.10
Kaolin 6.00
Flint 14.50
Totals: 100.00 %
Also add:
(Dark Red) Gold Chloride 0.50

Hi All,
This gold crown discussion raises some interesting
questions. First of all you need to find out if the
gold is 24k= I suspect it is not because pure gold
would be too soft to hold up on a chewing surface.
That means that the gold would be contaminated
with other metals. In 14k gold the gold content is
only 14 percent and the rest of it is copper with
silver.
An experiment I did last spring with white crackle
raku illustrates well the adulterant content. I took
a tiny cup and glazed it with a white crackle. I had
a vial of 14k gold filings from some previous jewelry
making so I thought I'd sprinkle some in the bottom
to see if it would melt. Well, it melted all right,
but the results were not what I expected. The bottom
of the cup had a distinct greenish brown crusty area
where the gold had been. Of course the green is due
to the copper and the rest I don't know. The brown may
be the silver or it could be iron contaminants from
my file.
Anyway, finding out what is in that gold crown would be
a good idea before you fire.
Regards,
