617087 Garnet Dark Frit 4oz Northstar Glass COE 33 Borosilicate

Northstar Garnet Dark is the most saturated self striking Ruby Northstar currently offers. It is best suited for thin stringer, thin blown work, and lip wrap. The self striking rubies are the next generation of colors offering the user cleaner, purer colors with less air and difficulty in working. When working Northstar Garnet Dark use a hot oxidizing flame. Once hot, Garnet Dark will turn transparent just as the standard Northstar rubies, but as it cools it turns a uniform ruby red. The strike is easily repeatable and the final color is not affected by kilning. Even after numerous reheats no livering will occur. Note that the final shade of red is darker than the initial color of the rod. Once heated and allowed to strike, the final color can be viewed. After prolonged use in sculptural and inside out applications, Northstar Garnet Dark can develop a deep brown hue. This can usually be reversed by heating the color until molten.  

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