Biscuit warmer

A biscuit warmer (also folding biscuit box or bun warmer) is a kitchen utensil, for warming and serving biscuits.

History
Biscuit warmers were first manufactured in Victorian England, first in Sheffield Plate and later in electroplate. They were designed to be placed by a fire to warm the biscuits and act as a serving vessel. In the 21st century they are mostly treated as collectibles.

Design
The boxes were made of a clamshell design and commonly had a screen on either side affixed to a divider in the middle. They could be brought to the table so diners could take a hot biscuit.
