Cobalt - Northstar
Of the four shades of cobalt blue Northstar produces, this ranks as the second lightest. Cobalt is well suited for small blown work, as well as sculpture when a medium transparent blue is desired. Cobalt Blue can take a lot of heat and can be worked in a wide range of flame settings. Though the color is extremely intense, be sure to stay out of reducing flames to prevent any dulling or graying.
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 color is awesome just saturated enough to be a nice dark cobalt color but not too saturated so you can work it hard and long and it won't get the gray streaks like the dark cobalt gets.... I keep a lot of this in the shop

I always keep an inventory of Northstar's Cobalt Blue on hand. I have used in many different applications and love the results. This color is not sensitive to the different types of flames and I have had wonderful results to include coil pot application. If you are searching for a beautiful blue, Cobalt Blue is one to try!
