617125 Jet Black Frit 4oz Northstar Glass COE 33 Borosilicate

Northstar Jet Black is a very dense black. It is well suited for sculptural applications and blown work. It is creamy and works easily, making it a welcome addition to the palette of blacks from which to choose. When working Northstar Jet Black, do so in an oxidizing flame. If worked in a reductive environment it will develop gray streaks on the surface and result in a dull matte finish. When applying the color, do so gently. After it is melted in it can take a lot of heat. Jet Black is great in combination with many colors and serves as a great background for striking colors. 

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