I use a rotating tumbler with steel shot (asst. shapes and sizes),
would that make a difference?
Probably not, It'll just take longer. Rotary tumblers are slower than
Also, the burnishing soap was purchased and is specified for silver
and another for gold. I was told to use about 1 tablespoon. It
really foams up, but has not overflowed the tumbler.
The main purpose of the burnishing soap is to act as a lubricant
between the shot & the items in the tumbler. I'm not sure a seperate
burnishing soap is needed for gold (unless you're doing industrial
quantities). I've used the same soap for both gold & silver. Haven't
seen any detrimental effects as yet. Actually, you can use any no or
low sudsing soap as a burnishing soap.
