NS-077 Deep Sea Blue is a fully opaque saturated blue. It is well suited for stringer application and blown work. For those of you searching for a substitute for NS-022 Polaris, this is the closest color to it. 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-014 Irrid and NS-015 Turquesa, and goes well with NS-063 Canary.
