Black Lightning - Northstar
Black Lightning is a very dense black with silver. NS100 Black Lightning can yield a mirror like blue metallic finish or if over-reduced an organic earthy tone. To keep NS0100 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 NS100 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 NS111 Alaskan Thunder.
Second quality glass can have the properties of odd quality glass, but may also have small stones, air bubbles, vary in tone/shade, or the shape can be very out of round. Both odd and second quality glass can provide a great value to the right person.
