Outcomes
-
Brilliant, sparkling blue with high clarity and vivid sparkle effectWork cool in a neutral flame. Build up heat base while tooling or manipulating the glass to maintain the sparkle and avoid developing a gray haze.
-
Gray haze on the surface — an undesirable result from insufficient heat base during workingGray haze develops if the glass cools too much during tooling or manipulation without a sufficient heat base maintained. Keep the heat base built up to avoid this.
Working notes
Garage: 975°F · Anneal: 1050°F
- Work cool but maintain heat base during tooling — insufficient heat base causes gray haze.
- Work in a neutral flame — as with all chrome colors, avoid oxidizing or reducing atmospheres.
