history of "Thermalware jars"
:
The company diversified in 1917 and began producing insulated cooking dishes, known as Aladdin Thermalware jars, for the U.S. military. These jars had an aluminum or steel jacket wrapped around a heavy glass receptacle. The space between was filled with cork. The introduction of the thermalware began the company’s venture into heat and cold retaining receptacles.
