Because these minerals are in the glass, they can react with one another when they come in contact. Some products have been developed for just that purpose. Oceanside has frit and glass called Red Reactive transparent and Red Reactive opal. It will react with any glass that has copper in it. It will give a deep reddish color where the reactive frit and copper-bearing glass intersect.

Reactive Guide – Oceanside Art Glass (oceansidecompatible.com) Vanilla Cream is a high sulfur content glass that is also reactive, it even changes from within. After full fusing the inside of the glass stays its pre-fused off-white color while the outside brightens to a vivid warm white. Oceanside Vanilla Cream Opal Glass (stainedglassexpress.com) Bullseye also has reactive products.
