context: There are over 10,000 objects made from silver or gold in the collection, the display (about 15% of the collection) is divided into secular and sacred covering both Christian (Roman Catholic, Anglican and Greek Orthodox) and Jewish liturgical vessels and items. The main silver gallery is divided into these areas: British silver pre-1800; British silver 1800 to 1900; modernist to contemporary silver; European silver. The collection includes the earliest known piece of English silver with a dated hallmark, a silver gilt beaker dated 1496–97. Silversmiths' whose work is represented in the collection include Paul de Lamerie and Paul Storr whose Castlereagh Inkstand dated 1817–19 is one of his finest works. The main iron work gallery covers European wrought and cast iron from the mediaeval period to the early 20th century. The master of wrought ironwork Jean Tijou is represented by both examples of his work and designs on paper. One of the largest items is the Hereford Screen, weighing nearly 8 tonnes, 10.5 metres high and 11 metres wide, designed by Sir George Gilbert Scott in 1862 for the chancel in Hereford Cathedral, from which it was removed in 1967. It was made by Skidmore & Company. Its structure of timber and cast iron is embellished with wrought iron, burnished brass and copper. Much of the copper and ironwork is painted in a wide range of colours. The arches and columns are decorated with polished quartz and panels of mosaic.
