Hi -
Does anyone out there in "Clayart Land" have a recipe for a gold colored raku glaze that works? The one I am using is just barely OK but most times looks more yellowish than gold. Any help will be greatly appreciated. TIA

Les, I have a really good one. It uses silver nitrate, which everyone thinks
is expensive, but I think the glaze is so beautiful, it is worth the price of
the ingredients.
I am reading mail at work, but please send a reminder to littlec@paulbunyan.net
and I will get it at home and send it off to you. Would you like to see a
picture of the bowl with the gold
glaze?

Les, I don't know about a gold colored raku glaze but I do know that some
folks use gold foil. It works very well......but it is quite expensive and
very fragile.

I have been using this for a month or two with good consistant results.
It may take a couple of test fires to learn it but it's a super nice glaze,
not like most patina recipes I've used.
Glaze name: Michigan Patina
Firing: Raku
Texture: Glossy
Color: Metallic patina
Cone: 08-06 - Closer to 08 ;P
Recipe: (Percent, Batch)
Gerstley borate 51.06 3.00
Cornwall Stone 17.02 1.00
Nepheline syenite 17.02 1.00
Copper carbonate 8.51 0.50
Tin oxide 4.26 0.25
Black nickel oxide 2.13 0.13
-------- --------
Totals: 100.00 5.88
Comments: I subsitute Black Copper Oxide @ 2.00
and reduce for 15-20 Minutes and usually don't submerg in water.
This is a great gold color when reduced in newspaper.
Use a container just larger than the pc. being reduced.
(3-4 inches of space around the pot).
And use minimal paper...I use one FULL sheet of newspaper torn in 4 pcs
length ways.
Two strips folded flat on the bottom to sit the pot on and two folded
around the sides of the can. If total gold is what your after just reduce
without burping the can for the whole 15-20 min. Don't submerg in water.
If colorful flash and gold is desired...put a hand full of shredded paper
on top of the pc. before capping the can. and burp after 12 seconds for 3-4
seconds..... then wait 5 - 10 minutes (I only wait 6 min.)....
Submerg. enjoy.
Let me know if you like it...I'd love to see some photos of your results.
Hope this helps....

The gold I've used had 2% silver nitrate with 4% bismuth sub nitrate
added to base glazes melting in the ^08 - 06 range. Gold works with a
good reduction or pale yellow without it. You can buy the materials from
Standard Ceramic Supply.
Keep in mind the silver nitrate is light sensitive so when it gets on
you and there is strong enough light, it turns dark and will be there
awhile is not washed off quick enough. I understand it is a poison when
ingested but silver nitrate was used by the vet to treat my dog's cuts
after he tried to run over a car.
Good luck,
Jim Tabor
