Product Description

Discover the huge range of borosilicate colors. Pack includes one 18" rod of Northstar's most popular colors, or about 95 rods in all! This economical pack also includes four samples of frit in assorted sizes. An ideal way to get a palette full of color.

Borosilicate is a "hard glass" with a COE of 32 and a higher melting temperature than other glass. Flameworkers love this lower COE because it means your finished projects will have a higher resistance to thermal shock and allows you to create larger or more elaborate sculptural pieces. A propane and oxygen torch is needed to achieve temperatures high enough to make this glass easy to manipulate.
