Bronwen Heilman takes a look at using marvers and mashers designed and manufactured by Trey Cornette, who is well-known for his ultrathin beads, twisted cane, and fine stringer work. The marvers and mashers are made out of heavy-gauge brass instead of steel, which Bronwen found to be helpful for holding the glass, making shaping easier. She also found the tools to be very well made and to have a good feel in the hand.
