I create my murrini from a variety of COE 104 glass. Night Glow is a mix of sky blue and ink blue. The result is a slight bluish tint coming through the sky blue coating. Black stripes finish this beautiful simple murrini. This murrini comes in packages of 20+ (I always throw in a couple extra). Sizes 3mm-7mm with average of 5-6mm. It has a smooth melt, will not scorch and melts evenly on enamels.
