Compare/Contrast

The piece of glass on the bottom of this sandwich actually began clear - it is clear reactive.  When it is fired it turns a translucent white.  Notice the difference between that color white and the smaller square, which is French vanilla. 

Glass sandwich #8 - Reactive clear topped with light cyan frit, French vanilla square, and small, irregular pieces of silver foil, and topped with clear.

 French vanilla actually begins as a beige-cast white and usually fires to this opaque white-white.  It seems to look even whiter when it has reacted with another glass.......is it really more white or does our vision work with our great brains to make meaning out of the contrast we see???????

 There must be a scientific way to compare color intensities and properties, right?  Paint stores have a way to match existing paint and sell you a gallon (or five,) of a matching color, so there has to be a mechanized reader/scanner of some kind!!

Compare/Contrast - Reactive cyan (blue frit)  and French vanilla (opaque white square), with silver on reactive clear.

Notice, once again, where the air patterns are in both of these pieces.  In both, there are bubbles along the edge of the most obvious color reaction.  These two pieces were fired together and in close proximity to one another, so that helps increase the chances that the properties of the glasses account for the bubbles, and not environmental kiln factors.

Also notice that there are not excessive bubbles over the silver pieces floating.  Is that due to the small size of the silver pieces, the distance between the silver pieces,  or the fact that the silver pieces are not touching the French vanilla piece of glass????  More experimentation needed.
