Additional Information

Turbo Cobalt

Turbo Cobalt is the most intense cobalt 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 its intensity, Turbo Cobalt must be worked in a highly oxidizing flame to prevent graying. If however you are looking for a battleship gray, it can be achieved by working Turbo Cobalt in a heavily reducing flame. For a nice color combination try layering Double Amber/Purple over Turbo Cobalt.

Available in Rod, Frit, Fine Frit, and Powder.
