This chamber pot was made around 1725 by Frederik van Strant in Amsterdam. A chamber pot or piss pot, potty, po, gazunder,or thunder pot) is a container with a handle, usually used as a urinal at night. It is kept in a bedroom under a bed or in a nightstand. During Victorian times, some chamber pots were built into a cabinet with a closeable cover.

The chamber pot was originally designed for females. Called the Bourdaloue, it allowed women to urinate squatting or sitting without accidents. It was supposedly named after the French Catholic priest Louis Bourdaloue, whose sermons were so long that women brought Bourdaloue so they could urinate without having to leave.
