Cassolette

Far aloft, over the Altar of the Fatherland, on their tall crane standards of iron, swing pensile our antique Cassolettes or Pans of Incense; dispensing sweet incense-fumes[.]

“Don't you like the word cassolette, Julian?” He supposed Thayer thought she was being clever. Cassolette was also a reference to the natural fragrance of a woman.

I know you're in a hurry to find out about cassolette, but please first note that “if you use your palm, rub it over your own and your partner's armpit area first.”

I'm still bemused by the original "cassolette", which turns out to be "the natural perfume of a clean woman: her greatest natural asset after her beauty", and definitely not to be confused with a small hotpot.
