611120 Northstar Silver Unobtainium Borosilicate Glass Rods

Northstar Silver Unobtainium is also a dark blue sparkle that has silver in it. 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 that may cause cracking. When worked in an oxidizing flame Silver Unobtainium stays a dark blue color with wispy hues of silver over it. If reduced the color does not show much sparkle but still has many vivid colors. 
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.
