19th c. Victorian silver vinaigrette
"In the early 19th century, there wasn’t garbage men that carted away the trash. People threw the stuff out the window. Slop pails went out the window in the 18th century. And when you left your house, you would encounter odors that made you just choke. So they invented a device called the vinaigrette. And it was a box or a little trinket carried to revive oneself if one felt faint.
So now they can’t breathe, they go outside, they smell the rotten garbage and the sewage, and they think they’re going to faint. They opened up their vinaigrette, which they held in their hand, and inside is a gold-pierced grill with beautiful decoration. But underneath the grill is a sponge. They would soak that sponge in an aromatic solution, sort of a mixture of perfume and ammonia, like smelling salts.” - Barry Weber, Antiques Road Show
