Cobalt - #25 Large Frit - 4oz. - Northstar
Of the four shades of cobalt blue Northstar produces, this ranks as the second lightest. NS001 is well suited for small blown work, as well as sculpture when a medium transparent blue is desired. NS001 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.
