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
