Georgian, George III, Old Sheffield Plate Warming Dish, circa 1790 - 1810. Most likely used for bacon, eggs or toasted cheese (with inserts). The turned and ebonised handle unscrews and hot water can be poured into a reservoir that would then keep the contents warm. Of rectangular form with reeded decoration and a domed cover with urn finial. A chain, located on the handle stem, locks the cover into an open position.
In excellent order with light surface wear, commensurate with age. Small areas of copper bleed and some pitting to the interior.
Approximate weight is 1.6 kilos.
Approximate dimensions are 25 cm length, 31.5 cm width (including handle), 18 cm width (dish only) and 13 cm height.
