Silver Reaction????

Doing more experimentation with silver foil, French vanilla and cyan or light turquoise did not turn out quite the way I expected.  I decided to use frits, and cut out silver stars on a clear base.   Below you car see a cobalt frit (the darkest blue, French vanilla frit, lite cyan and silver stars.

 The plate example above uses only three colors of frit.  All of the stars are cut from the same material and are exactly the same size.  The first stars that are very visible look like they are dark gray and outlined with brown or charcoal gray.  These silver stars have reacted to the French vanilla they are resting on top of.

The five stars that are the most visible in the image above all appear to have reacted the same way and turned a translucent gold.  Surprisingly, these stars are resting on three different colors of frit.  I expected all stars on top of French vanilla frit to react by turning dark and revealing a clear reaction boundary line like the first image.....hmmmmm.

This portion of the plate shows all three colors of frit, reactions between the French vanilla and cyan (which looks sandy brown where it has reacted,) and stars that have both reacted and turned brown AND reacted and turned translucent gold.  So, what is the magic combination - GOOD QUESTION???

The presence of the brown reactive French vanilla and cyan appears to have a reactive effective on the silver stars a LOT of the time, BUT not ALL of the time!
