Northstar Plum Krazy boro glass is a dark transparent faux purple that strikes to a rich smoky blue. Work in a cool oxidizing flame to prevent overheating and striking the color. When ready to strike, either kiln at 1050F or bathe the glass in a gentle bushy neutral flame to bring out the soft blue strike. This color is best suited for moderately thick coil-potted blown work and sculptural applications. When encased in clear this color produces a vibrant violet with wisps of metallic blue. Be sure to try it over NS-054 Star White or NS-081 Blue Caramel. Prolonged reduction leads to a grayish blue opaque surface.
