Primus stove

Before apartments had central gas (or electricity), many Muscovites cooked on primus stoves, which used kerosine or cooking oil and worked something like a Coleman stove, with a burner atop a tank.

This primus stove, in Bulgakov's Apartment on Sadovaya, is from the same period as those encountered in the novel
