NS-103 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 colours as NS-14 Irrid and NS-15 Turquesa, and goes well with NS-63 Canary.
This is a full rod measuring 6-7mm dia x 480mm -500mm long.
