Red Reactive glass Rods provide an unique look when fired with certain colors. This unique glass formula for System 96 creates an interface color or "reaction" when melted against certain other colors. The primary ingredient needed in a glass to generate a reaction color with our Reactive glass is Copper. Copper is present in many blue and blue-green glass colors, but in some cases in too low a concentration to create a noticeable reaction. COE96. 10 rods per pack. : 10" long x .25" diameter.
