617100 Black Lightning Frit 4oz Northstar Glass COE 33 Borosilicate

Northstar Black Lightning is a very dense black with silver. Northstar Black Lightning can yield a mirror like blue metallic finish or if over-reduced an organic earthy tone. To keep Northstar Black Lightning most vibrant, work in a super oxidizing environment until you are finished with the piece. Then, turn the flame down and bathe the piece in a super reducing flame for several seconds to produce the mirror like sheen. For another great effect, encase Black Lightning with clear. This color can be stretched out and is great for blown work. If heavily encased, be sure to anneal thoroughly. This is the bigger brother of Northstar Alaskan Thunder.    

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