I create my murrini from a variety of COE 104 glass. The colors remind me of the near harvest of a field of wheat. Golden with a bit of green ads a warm glow to your glass. Sizes 3mm-7mm with average of 5-6mm. This murrini comes in packages of 20+ (I always throw in a couple extra). It has a smooth melt, will not scorch and melts evenly on enamels.
