Over the years many of the Staffordshire potteries
used a trading name for their wares and normally used this as
a backstamp
Trading Name - Tuscan
China
Pottery - R H & S L Plant Ltd
To a collector, the backstamp mark can be of great importance
for, not only can the manufacturer be traced from this mark, but
the mark can also ascertain the date of manufacture and in some
cases, the exact year, particularly from such companies as Mintons,
Wedgwood, etc., which employed private dating systems
Backstamp marks are usually applied in a few different ways
They are either impressed into the soft clay, incised into the
soft clay, painted onto a fired piece and glazed over, or transfer
printed onto or under the glaze
