617079 Blue Spruce Frit 4oz Northstar Glass COE 33 Borosilicate

Northstar Blue Spruce: Just as trees have growth rings; Blue Spruce will develop steely blue striations on the surface of the glass. Reduction develops these striations or rings. If kept oxidized, Blue Spruce will remain pure and offers a fully saturated blue-green opaque for stringers and blown work. Try reducing, then casing with clear glass for a neat effect! Amber/Purples look great with Northstar Blue Spruce as well. This color is a must have in any palette.   

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