A few weekends ago, I took a polymer clay recycling tip and separated my broken beads and tiny stringer remnants by color. Then I smashed them into frit. What you see below are my containers of frit and some of the beads I made with it.
I have an unorthodox method of using the frit; I melt the end of my Moretti Rod, dip it into the frit container, introduce it slowly back into the flame and melt the colors in. I repeat these steps a few more times then I wind the glass onto the mandrel.
Here’s Lampworker Tom Wright on YouTube showing how he adds frit to beads.
