Just got the new Lapidary Journal today and there is a brooch of
fine silver with gold burnished onto it. How does one do that?
Hi Dave. I was curious about that as well. My teacher told me
it was the Kumboo method (described very well in McCreight’s
Metal Technic book). Basically, base piece is heated over low
heat (say on an electric stove top or hot plate). 24K gold foil
is cut into shape desired and applied to piece with a wet brush.
Piece is heated more, then gold is burnished onto piece with a
burnisher. Just bought the gold foil at Metalifferous but
haven’t tried it yet. Take a look at the book chapter though
for the exact details.
