611119 Northstar Super Unobtainium Borosilicate Glass Rods

Northstar Super Unobtainium is a dark blue sparkle. This color has lots of large crystals of metal on the surface. It is well suited for stringer application and blown work. It is easily worked and can take a lot of heat. To keep the color most vibrant, work in a neutral to slightly oxidizing flame. Try to avoid deep encasement as it may cause cracking. Please use Northstar Super Unobtainium with care and test before you make any thing that is expensive. Outside work seems to work just great with no problems. Try coating Northstar Super Unobtainium with Garnet or Pomegranate to achieve a brilliant ruby sparkle. Any transparent color coated over Super Unobtainium looks great. Northstar Super Unobtainium has lots more sparkle but does not have the Gun Metal surface of Northstar Unobtainium. 

Size: Diameter 5-7mm, length 20", weight per rod .07 lb. All Northstar rods are first quality.

ATTENTION: Due to the weight and length of the rods you may receive .30 pound vs .25 pound (as an example) when ordering. This will cause the cost to rise and the amount you expect to pay for your glass may change.

If this is a problem, please let us know and we will “underweigh” your glass. This means instead of .25 pound you may receive .20 to .22 pound. Please be aware that it is almost impossible to pull exactly .25 pound. We will always try our best to get as close as possible to the weight that is ordered, but due to the factors stated, these weights may substantially increase the total cost of your order.
