Product Details
NS-20 Dark Cobalt is the second most saturated of the four shades of cobalt blue Northstar produces. Dark Cobalt is well suited for thin blown work and cane work. Because of its intensity it must be worked in an oxidizing flame to prevent graying. Refer to Northstar Newsletter issue 16 for additional information about working cobalt blues.
