I like to use frit for some of the beads I make, like the bracelet I made a couple of days ago. Frit is smashed up glass that usually comes in particular colour blends. I put the frit in a little metal container, then make the bead, roll it in the frit, and then heat the bead so that all the frit is melted in to the bead. This is how I can get some different colours into the recycled glass beads that I make.
