Cobalt 5 - #25 Large Frit - 4 oz. - Glass Alchemy
Working Tip: Work in neutral flame to avoid reduction (gray streaks)
Artist Description by Mike Shelbo:
Cobalt-5 is very dense in color concentration, yet not as stiff in workability as Cobalt-6. Be sure to use a neutral flame with this color as it can be susceptible to over reduction that will leave grey patches or streaks. Cobalt-5 is great for stringers and blown work that will leave you with a true deep cobalt. Sandwich between clear layers and blow out thin for a vibrant and beautiful cobalt blue transparent. Works nicely, and melts easily into itself with no mark or sign of where glass was added. My favorite Cobalt-5 quality is that it shines through the color when it is brightly back lit.
