As per Tom Rosenbusch's post in 100915 MMDigest --  The mini crock
pots work extremely well as they maintain the correct stable temp
when filled with water and the jars of glue inserted, and I have
such a vintage appliance which I will give for mere postage if anyone
wants it.  It is in excellent condition and I am not "in the business"
any more.
