Guarded Hot Box

Description:

This seems to be a guarded hot box for determining the insulating properties of various materials. A brass tag on the front reads "JOHNS MANVILLE / INSULATION." Inside are two metal vials, one with a "GAERTNER" inscription. The Physics Department at Rutgers University donated this to the Museum in 1966.
