33 COE borosilicate glass rod by Northstar.

NS-070 Ice Blue is a lush copper blue that has eye catching appeal. It is a light transparent color but it adds great optical depth even in thin layers. It is not suitable for stringers or cane work, but it is great for sculpture and blown work. Its effect as an overlay color is impressive.
