Berry Gumbolt Fine Frit 4 oz. (70 grade)

Berry Gumbolt is a fully opaque saturated dark blue. It is well suited for stringer application and blown work. It is not susceptible to reduction and is not flame sensitive. For best results keep it in a neutral flame. It is a great backing for such colors as NS-14 Irrid and NS-15 Turquesa, and goes well with NS-63 Canary.
