Torch fire enameling is the process of fusing Fine enamel glass powder on to metal such as copper, steel, silver or others.
This is a labor intensive process as first the metal sheets need to be cut to shape, filed, prepped etc.
Then they are coated one thin layer at a time, front and back so that the glass tension on the metal is even.
Each layer combined with the previous one and with the action of the torch blends in organic and sometimes unexpected ways.
Paints and other compounds (metal leafs, glass beads etc) can be added during the process for varied results.
Depending on the size, colors and effects desired one little enamel plate could have 2, 3 or 4 layers added on either side.
