The Royal Worcester standard printed factory mark includes the number 51 in the centre which refers to the year 1751 when the Worcester Porcelain Company was founded by Dr. Early standard marks show the crown slightly above or perched on the circle and from 1876 the crown sits down onto the circle. In 1862 with the restructuring of the Royal Worcester company and the introduction of a new factory mark came the first of the new Worcester date coding sequences.
This tends to protect the use of these marks, and in general restricts them to use on pieces made in the UK.
This protects both collectors and the companies who registered the marks.
These could be printed or impressed under the circle but like all impressed marks these could be difficult to see when they fill with glaze.The Coalport porcelain manufactory was a market leading pottery throughout the 1800s, it produced a staggering range of porcelain products of all shapes and types.Seemingly Coalport was named Coalport because of the coal that was transferred from canal boats to river vessels in the Coalbrook Dale area. Very early Coalport porcelain was unmarked, (c1805 and before) and in reality marks were rarely used before 1820.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.
