glass in clay

Hi,
I have a friend that wants to use glass beads incorporated into clay objects.
Has anyone done this? What was the outcome?
At what temperature does glass melt?
I was thinking about bisqing to about ^015-016 then rakuing - watching until
the glass begins to melt then pulling it out.
thanks for the help

Hi Wendy,
Depends on the glass type but generally glasses have softening points
from 450 Celsius upwards. A low soda high lime glass may have
sufficiently high viscosity and surface tension to stay as beads/blobs.
But the best thing to do is try it (with a scrap furnace batt underneath
in case it doesn't work..)
After all they can keep the chocolate chips in the cookies while they
cook and chocolate melts at blood heat..
