Old Utensil - Chamber Pot

The word utensil can refer to a tool that serves a specific purpose, or has a specific use.

A chamber pot was simply a bowl or bucket designed for one to do their “business” in, when one couldn't - or didn't want - to leave their house to take care of it. It was common in many cultures before the advent of indoor plumbing and flushing toilets. A chamber pot was also known as Jordan, po, potty, a chamber utensil or bedroom ware. In the England's West Midlands it was called a “guzunder” because it “goes under” the bed.

The purpose of a chamber pot was a portable toilet, meant especially for nocturnal use in the bedroom. It allowed people to relieve themselves privately. In the morning, contents were often tossed onto the street, creating major health hazards. Sometimes they were emptied into cesspits. Cesspits were large holes dug into the ground. Often they were designed to be porous, so that liquid waste soaked away into the soil, leaving solid waste to be removed, or covered over, when the pit was full.
The “privy” - an “outhouse” - was an outdoor wooden structure built over a cesspit of some kind, but not everyone had one. Inside the structure, a wood plank served as the seat. A round hole cut in this plank allowed the waste to fall down into the cesspit.

A chamber pot was often kept under a bed. Or it could be hidden in a kind of chair (“a close stool”). It could also be stored in a cabinet with doors to conceal it. Wealthy owners owned highly decorated, plush models.
En route, chamber pots were stored under the seats of the carriages.

A related item was the bourdaloue, a narrow, handheld oblong ceramic pot used in 17th- and 18th-century France to allow women to urinate conveniently. This item, similar in shape to a deep gravy boat, could be held between the legs, and urinated into while standing or crouching, with little risk of soiling the clothing. It was reputedly named after the French priest Louis Bourdaloue, who was renowned for his lengthy sermons.
