A simple chimney crane hangs over the fireplace. This enabled the position
of the pot or kettle to be varied. If the height of the pot hook could be
altered this provided a surprisingly accurate method of adjusting the temperature.
The finishing touch was the addition of an idleback, a device that allowed
the kettle to be tipped without having to take it off the pot hook. This
was most useful, as a large kettle full of boiling water was a difficult
and dangerous object to manoeuvre. Boiling water was used for many cooking
purposes in the kitchen as well as for hot drinks such as tea and coffee.
