But the problem is that this application will be used to work with
molten glass . There's a glass bead maker here that wants me to make
some rods for making the beads . The "working end" of these , that is in
actual contact with the glass , is carbide* , the "handle" is steel .
I'll be getting more info from her when we get together next week , but
would like to have some ideas in hand by then .

Commerical brazed-tip cutting tools use bronze brazing. I have some
homemade ones that were silver brazed.

There are brazing alloys that are made specifically for brazing
carbide cutting tips onto steel shanks. Handy &
Harman/Lucas-Milhaupt's Easy-Flo 3 is one that's been around for
decades, if you don't mind the cadmium. There may be newer ones. Watch
the solidus temperatures if they're to be exposed to molten glass.
Easy-Flo 3 is 1170 deg. F.
