glue pot
A container, frequently made of copper and usually
of a double boiler construction, in which glue is
melted and kept at the proper temperature, which
is in the range of 120 to 150° F. It is heated
by gas, or, more often today, by electricity,
either through a water jacket, or directly through
insulated walls. It is usually controlled by a
thermostat if heated by electricity. Control of
temperature is important, as overheating of animal
glue results in a loss of gell strength. (183 , 335 )
