    Wendy, I do not know a source for asbestos sheets except maybe
    unwind the inards of a wound soldering block available from most any
    jeweler supplier. But I have a question for you - or rather for your
    teacher. I have been casting for around 25 years and have never used
    asbestos or other liner in my crucibles!  Why do you?  I use a
    seperate crucible for each metal and give it a good lining of borax
    with creates an excellent glass like surface. If you periodically
    flux the crucible it should last a very long time. I have read in
    some casting books about using asbestos but never quite understood
    why except maybe to preserve the crucible.  In my opinion, the
    asbestos could become uneven and cause turblance when the metal is
    injected. It could also burn away and produce unwanted ash that may
    be carried into the pattern chamber.
