Daniel, try Allcraft in NYC, I’ve had good luck with their foil. I
have tried the gold foil from Thompson Enamel (an excellent supplier
that has always filled my orders with speed and courtesy) and found
it a little bit too thin. It tended to sink into the silver.

PMC Connection has gold foil, but when I asked them what its
thickness was, they didn’t know and didn’t seem to know how to find
out. I suggested they ask the manufacturer, and they said they’d
call me back, but they never did. I don’t want to order it and find
out the hard way that it’s too thin. Art Clay World may carry it, I
still have to check that out.

I would also be interested in hearing about other sources of supply.
The foil should be between .01 and .06 mm for best results.

Daniel,

Do you want leaf or foil? I use foil, which is much, much easier to
use with a better result. Allcraft (800-645-7124) has very thin
foil, and Art Clay World (866-381-0100) has heavier foil that is
about the weight of heavy weight aluminum foil.

Good Luck!

Hi Daniel Unfortunately I do not know of anyone who offers 24kt
suitable for kumboo. I prepare my own by rolling 24kt gold coins down
to 0.03mm. This is the thinest that I can get on my rolling mill
without using copper sheet or a similar soft metal as a spacer. I use
Canadian Maple Leaf gold coins as they are 0.9999 pure. A 1/10
ounce coin makes a huge amount of kumboo material.

Milt, where can one order the Canadian coins? I’m interesting in
rolling my own foil.

(Egad, I remember in the distant past when “rolling your own” meant
something a bit different).

You can get the Canadian Maple Leaf coins from coin shops that sell
commerative coins or any metals exchanges that carry small precious
metal ingots for collectors. I buy mine at Albern Coins in Calgary.
They are readily available in Canada, but I am not sure how easily
one can get them in the United States.

I understand that the Kugerand is also .9999 pure and should work as
well as the Canadian Maple Leaf Coin. There are probably other
sources for pure 24kt gold. I use the Canadian Maple Leaf because
it is easily available at market price with a low mark-up added on
top for the seller.

I also used to buy one ounce Franklin Mint Sterling silver coins and
roll those in my mill to make sheet sterling silver. I would by the
coins from the “scrap silver bin” at a much lower cost than the cost
of finished sterling silver sheet. I have since started buying all
of my silver sheet and wire from a refiner.

Hi Mona,

I use Canadian Maple Leafs exclusively to make 22 kt gold for
granulation. The Canadian Maple leaf AFTER 1984 (might be 1982) is
four-nines 0r 99.99% pure gold. Before that, it is 99.9% and not
pure enough for granulation purposes. Drawing it into wire, making
jump rings, and then trying to weave the jump rings as per Jean
Stark, and the jump rings break. I got to demonstrate that in her
class once…not on purpose of course….

For keumboo, I take an ounce of pure gold, heat it on a charcoal
block until it is molten, then pour it into a tumbler of water. It
will make small granules of gold the size of BB’s. I then flatten one
of these on my steel block and then run it thru the rolling mill till
the rollers are touching. I have some stainless thin sheet, and
sometimes use it sandwiched with the 24kt gold if I need to go
thinner.

They come in 1 ounce, half ounce, quarter ounce, and one-tenth
ounce. They are sold as bullion, and you should expect to pay about
5-7% over the cost of gold for the piece. Here is a link describing
them. http://www.goldline.com/mapleleaf.htm

I buy mine from Dallas Gold and Silver. You might look in the phone
directory for a bullion dealer in your area. You can’t use check or
credit card when buying bullion. Cash only.

Love and God Bless

Kugerrands are not pure gold. They are alloyed with copper. I believe
they are 22KT with the balance copper. You can confirm this with a
coin dealer or do a little research online.

if it must be thinner than your mill can go, sandwich it between two
sheets of metal and keep rolling!
