617120 Silver Unobtainium Frit 4oz Northstar Glass COE 33 Borosilicate

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.

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