Gold Foil for Keum-Bo

The Process: Put the work onto a hotplate and turn it up to High. To test the heat of the PMC object, touch a toothpick to it. When the wood chars, the metal is hot enough that the fusing process has begun. At this point, secure the object with one hand as you lightly press the gold  foil or Aura 22 down against the silver. The goal of this step is to press out microscopic gaps that exist between the silver base and the gold layer. When the two pure metals are in perfect contact, bonding is instant.

Generally, start with a light stroke, then rotate the piece and follow up with firm-er pressure using strokes that run in a different direction from the first. You will notice that the burnisher leaves marks; these will be removed by polishing after the layers are bonded.   If the color is weak, or if you have changed your idea for the piece and want to cover a larger area, you can add on additional gold and repeat the process. It is also possible to combine traditional keum-boo and Aura 22 on a single piece.
