FOLDING BISCUIT BOX
BISCUIT WARMER

This is a type of biscuit box in the form of a stand having two or three bowls hinged at the bottom.
When the device is closed the bowls rise to a vertical position fastening to the central column. The column has a loop handle or an ornamental finial.
The bowls drop to a horizontal position when biscuit box is open. Each bowl has a hinged flap with pierced work to help retain the warmth.
They are sometimes called Biscuit Warmer.
There is no warming device inside but they were stood in the hearth and turned frequently so that all sides could be warmed by the fire. The biscuits inside warmed accordingly, the whole was then lifted to the tea table and opened and the warmed biscuits/teacakes/buns were available (information courtesy Josephine Lewis)
