In the case of the larger firms the mark also has publicity value and shows the buyer that the object was made by a long-established firm with a reputation to uphold; such clear name- marks as Minton, Wedgwood, Royal Crown Derby and Royal Worcester are typical examples.
It was a requirement of this Act that all such imports carried the name of the country of manufacture.
This provided well-known marks such as "Bavaria," "England," "Nippon," - indicating the country of manufacture.
Worcester dinnerware traces its origins back to 1751, when it began producing porcelain in Worcester, England.
What collectors know in modern times as Royal Worcester bone china dates from 1862, when the company became the Worcester Royal Porcelain Company.
With the increasing use of ceramic marks in the 19th century, a large proportion of English pottery and porcelain can be accurately identified and often dated.
'England':- Inclusion of the word 'England' in marks denotes a date after 1891, although some manufacturers (Thomas Elsmore & Sons for example) added the word slightly before this date. It was William Mc Kinley (the 25th president of the USA) who introduced the highly protectionist Mc Kinley Tariff Act of 1890 - this imposed tariffs on many imports (including pottery) in order to make it easier for the American manufacturers to sell their products.
From that, you can get a sense of your china's value and history.
Thus the dating of Royal Worcester products begins in 1862.
In 1976, the company merged with Spode, but still produced porcelain products.
In 2009, the Worcester factory closed and the trademark name purchased by Portmeirion Potteries of Stoke on Trent.
In addition to its famous bone china dinnerware, the company also produced earthenware and decorative objects like vases and figurines.
