Northstar Glassworks 033 Turbo Cobalt Rod 33 COE Borosilicate glass.
NS-033 Turbo Cobalt is the most intense blue in the Northstar palette. It is great for stringer application and stretching out thin. If kept moderately thick, Turbo Cobalt is an excellent faux black. Because of it's intensity, Northstar Turbo Cobalt must be worked in a highly oxidizing flame to prevent graying. If however you are looking for a battleship grey, it can be achieved by working Turbo Cobalt in a heavily reducing flame. For a nice color combination, try layering Northstar Double Amber/Purple over Northstar Turbo Cobalt.
