Vitrite, also known as foam glass, is a very low fusing point black glass mainly used for the insulation base of electric lamps. It was formerly made by the Vitrite Company.


To make the electric lamp, molten vitrite is poured into the shell up to a height of approximately a quarter inch (6 millimeters). A plunger is brought down to force the plastic glass into shape and fix the contacts.


Vitrite is referred to as glass but in fact it is an enamel which contains a high proportion of lead (II) oxide to give fluidity, and considerable quantities of manganoc (probably a manganese oxide) to produce a black colour.
