In a committee of MPs was set up to revue evidence regarding the pirating of designs in British industry. Seven years later in the need for copyright of design was recognised and an act was passed in Parliament to give the manufacturers legal protection for their designs. Over eight thousand designs were registered in the first year — Once recoginsed as a viable safeguard for design ideas the system steadily grew and by registrations had gone well over sixteen thousand. This in itself caused problems as the system was somewhat complex so the implementation of a simpler version was introduced. The initial procedure involved allocating numbers and letters to each design but this became harder to keep track of, so on 1st January the diamond registration mark was dropped and a new system was introduced, this scheme still exists today in the same form. I have included a chart to show how the Material, Year, Month, Day and Bundle are worked out and once examined it really is self explanatory.

Next is the letter W, if you look at the chart figure 2 you can see that this is for the month of March. So the date of registration for this item is 26th March

These were minor inventions and had registered numbers which were usually found on the artefacts.
A hallmark is an official mark or series of marks struck on items made of metal , mostly to certify the content of noble metals —such as platinum , gold , silver and in some nations, palladium. In a more general sense, the term hallmark can also be used to refer to any distinguishing characteristic. Historically, hallmarks were applied by a trusted party: the “guardians of the craft ” or, more recently, by an assay office.
Hallmarks are a guarantee of certain purity or fineness of the metal, as determined by official metal assay testing. Hallmarks are often confused with “trademarks” or “maker’s marks”. A hallmark is not the mark of a manufacturer to distinguish his products from other manufacturers’ products: that is the function of trademarks or makers’ marks. To be a true hallmark, it must be the guarantee of an independent body or authority that the contents are as marked.
Thus, a stamp of “” by itself is not, strictly speaking, a hallmark, but is rather an unattested fineness mark. Many nations require, as a prerequisite to official hallmarking, that the maker or sponsor itself marks upon the item a responsibility mark and a claim of fineness. Responsibility marks are also required in the US if metal fineness is claimed, even though there is no official hallmarking scheme there. Nevertheless, in nations with an official hallmarking scheme, the hallmark is only applied after the item has been assayed to determine that its purity conforms not only to the standards set down by the law but also with the maker’s claims as to metal content.
In England, the year of marking commences on 19 May, the feast day of Saint Dunstan , patron saint of gold- and silversmiths. In other nations, such as Poland, the hallmark is a single mark indicating metal and fineness, augmented by a responsibility mark known as a sponsor’s mark in the UK.
Over the years factory marking of pieces has evolved and although marks vary from impressed and hand written to printed emblems, the majority of bone china produced was marked in the way described below.

Wileman , and a variety of backstamps were used over the years. In Wileman began earthenware production in a new earthenware works. Wares produced in the new works were labelled with unique backstamps. Beginning in , the Shelley backstamp replaced Wileman and Co. Backstamps are often the first thing a collector looks for. Although a backstamp may be an indicator of authenticity, the backstamp alone is insufficient to guarantee genuineness.
Counterfeit backstamps have been applied to ordinary pottery, and in some cases transfers have been applied to bona fide Shelley whiteware. To complicate matters, some genuine Shelley pieces have no backstamp at all, for example salt and pepper shakers. Special thanks are owing to Mr. Bruce Sandie and the Australasian club for their generous assistance in providing research and artwork necessary to the creation of this page. The UK Club has an extensive discussion of backstamps which they have shared with us.

DATING ENGLISH POTTERY & CERAMICS. The diamond-shaped English Registry mark, was used by the English patent office from to to identify.
There are features that distinguish one type of lead-glaze majolica from another to a great or lesser degree which we mention as we go along. The main types are English majolica, which we will cover in more detail including sections on English Style, Makers and Marks; Continental majolica; Palissy majolica; American majolica; and Green.
They were commercially inexpensive to produce as many colours could be applied to the biscuit, then fired just once, ideally without running into each other though this was not always possible. The process of applying coloured lead glazes to the biscuit , then firing, is known as ‘majolica glazing’. Green glazed leaf plates rely on the ‘intaglio’ effect where glaze accumulates in the depressions of the mold as a stronger color.
The new majolica was simultaneously boldly decorative and useful. It became hugely popular with the rapidly emerging merchant classes of Victorian England. Some established households also approved, including Royalty. Within a few years many pottery firms had moved into lead-glazed majolica. New contenders strove to establish their own businesses, George Jones being one of the latecomers, to some collectors the finest of them all.
Lead-glazed majolica enjoyed a heyday. But by the ‘s in England the passion was fading. By majolica manufacture in England was at a low ebb, many artisans emigrating to the US where interest in majolica was alive and well. Within ten years the lead-glazed product was pre-eminent, copied by potteries world-wide, mass-produced and in many styles, formal or informal, classical or naturalistic.
The answer, of course, is “yes, but It’s a good idea for you to do a search before you adopt a mark. Chances are, your first choice or two will be taken, so a little investment in your time now will save you a lot of time and money later on. There’s no point in paying us to file an application to register a trademark if it’s already registered and you could have found it in a few minutes work, and if you can knock out all the “easy” ones, you will get much more value from a professional search later on.
There’s more than a little art to searching, not to mention years of experience, so don’t feel too bad at missing something a professional might find.
