Northstar-01 Cobalt Blue is well suited for small blown work, as well as sculpture when a medium transparent blue is desired. It 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.
Refer to Northstar Newsletter issue 16 for additional information about working cobalt blues.
