Turbo Cobalt - Northstar
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, NS033 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 NS026 Double Amber Purple over NS033 Turbo Cobalt.
Second quality glass can have the properties of odd quality glass, but may also have small stones, air bubbles, vary in tone/shade, or the shape can be very out of round. Both odd and second quality glass can provide a great value to the right person.

This is one of the most versatile colors in my pallet.

Great for production work. Can grey out if reduced. Just blast the oxygen when working to keep deep blue color. Cheap too!
Can Have an Appearance of Opaque or Transparent

Turbo Cobalt is such a dense color it can be pulled down to create a transparent blue or when used as is can appear like an opaque blue. If your work requires a reducing flame, it’s best to encase Turbo Cobalt first to avoid greying (unless a flat greyish finish is what you’re going for). Otherwise work it in an oxygen rich flame. I use Turbo Cobalt all the time. It’s my go to.
