The pottery of S & E Collier Ltd ran for over a century in Reading, Berkshire, before closing in 1957.
Their terracotta pots were marked, from the last quarter of the nineteenth century onwards, with a large 'C' over a smaller 'double-R'. They also used the trade name 'Silchester Ware' and the mark for this brand was the words 'SILCHESTER WARE' impressed in an eye-shaped device.
