Silver Foil (high fire)

Trying experiments with High Fire silver foil. 
1. (from left to right) - fired glass on High.  The foil disappeared and left a slight sheen behind.

2. Fired two small pieces of clear glass on a Medium heat - the silver foil stayed.  I was a bit worried about over fusing the glass again.

3. Fused the foil between 2 pieces of clear glass, and fused on Medium heat, for a little longer, until the glass melted/fused.  The silver foil stayed - and still looked silver.  This was the best method.
