A New Discovery about Chunky, Clear Frit

Reactive clear (that fires to a translucent white,) topped with a conglomeration of frits (French vanilla, cyan, spring green, chunky clear, ) and topped with clear.  

Notice the difference in the number of tones and shades in the example below when French vanilla is not included in the mix.  There is not interaction between the different frits. 

Reactive clear on the bottom, followed by periwinkle blue, spring green and chunky, clear frit and topped with clear 90 COE.  This piece also includes a small number of white, dicro frit in the frit middle - these are the pieces that appear to be metallic.

In each example, however, the proximity of large, clear frit "chunks" seem to result in a large air bubble in the middle of wherever the chunks are located; this type of bubble is present in each trial where chunky clear frit is used.
