RE: [ATM] Making glass blanks.

Home ranges have standards for surface temperature on the sides and doors.
There are NONE for the cook top.

Much above 900 degrees and the GE's will shut down.  I imagine most of them
will.  Plus, I have had sporadic reports from customers telling me that they
shut down during marathon bake sessions.  Also, the door will lock up.  That
may not be a problem
