Working notes Part of a series that includes Reactive Ice Clear (001009) and Red Reactive Clear (001019). Reactive Cloud Opal is designed to react with copper-bearing styles and also reacts with silver. Reactive combinations have the potential to create an interface color, which may continue to develop through multiple firings. When combined with some copper-bearing styles Reactive Cloud creates an interface color that tends to be variations of pink, to red, to almost black. When combined with silver the reactions are more likely to develop as earth tones. Reactions are generally related to the amount of copper and/or silver within the components, heatwork, and surface area contact between the reactive components. Bullseye Compatible.
Reactions This is one of Bullseye's Reactive glasses. It reacts with copper-bearing glass, copper leaf, and silver where they meet.
Using the stringers Stringers are thin, uniform rods you lay on the surface to draw lines, borders, lettering, and fine detail. They fuse flat into the glass and can be snipped, bent with a little heat, or arranged into patterns before firing.
Fusing and compatibility Tested compatible with other Bullseye glass. When you combine it with glass from other makers, matching COE alone does not guarantee compatibility, so fire a small test tile first.
