TUNNELS & PLUGS:
1) Lay down a footprint shorter than the 11mm wide cavity. Don't worry, as you marver they grow because people tend to use more pressure than needed to shape, so start short.
2) Lay down your glass on the outer rims. As you shape the glass will fill in the curve without overfilling it.
3) The bead is formed on the upstroke coming out of the cavity, just like in all of the beadrollers, a tip learned from marble making. Pay attention to it coming out of the cavity, you can see it conform to the cavity shape. If it spills over into the mandrel/punty slots, you are using too much pressure when rolling.
CGBead tools are the premier graphite beadroller, and bead-press, tools of the hot glass industry.
Graphite mold made for the lampwork industry.
(beads not included)
Beadrollers not only help you with those difficult curves,
but also act as a measuring guide once your first bead is in the kiln.
There's no more guessing if the next one will be the same size!!
There's also a handy little area for marvering on the front. The reversed side is a flat marvering surface.
