Reactive Glass When Not Provoked

French vanilla glass, which is wonderfully reactive when next to cyan, simply fires to a creamy while when not provoked to react.  Next to a clear brown topaz, French vanilla just does its own thing.  In the stripe pattern in the first image below, both glass colors hold their own and maintain a non-reactive edge.

When assembled in an image, as in the pseudo sand dollar below, both glasses maintain their integrity.

These two patterns, stripes, and the sand dollar are combined with a clear cap to be double fired.

 The first firing fused all of the individual pieces together and the second firing "slumped" the rectangle into a serving-plate shape.
