Charles, et al.

Another source of carbon could be carbon piles.  Some old battery testers
use them and might be available from surplus outlets.  Although more of a
specialty item, carbon tools are used in glass blowing and vacuum tube (and
CRT) manufacturing to shape the softened glass.  It is preferred due to its
extremely low thermal conductivity, which doesn't crack the glass.
