617101 Purple Urple Frit 4oz Northstar Glass COE 33 Borosilicate

Northstar Purple Urple is a dark purple that looks like Northstar Hyacinth but works differently in the flame. This opaque purple uses chrome technology but does not have cracking problems. It is great for blown work and thin stringer application. It is heat and flame sensitive so it must be heated up slowly to prevent boiling. Once it glows red, Northstar Purple Urple will take heat well. Because of it's intensity, it is sensitive to reduction. If the flame is not oxidizing enough, gray and brown streaks will develop on the surface of the glass. Try it with a layer of Northstar Violet for a deep purple effect.   

CAUTION: AVOID EXPOSURE TO GLASS DUST. ALWAYS USE A DUST MASK AND EXHAUST HOOD WHEN HANDLING FRIT AND POWDERS.
