THE VICTORIAN ANTIQUE GLASS REGISTRATION LOZENGE (DIAMOND) MARK TRANSLATOR
This translator gives an easy to use method of dating, and finding the manufacturer of, any antique glass item registered in England between 1842 and 1883
It can also be used to give the correct date of design registration for any china, metal, paper or other non-glass registered lozenge but NOT the manufacturer.
Firstly, You need to determine which Victorian time period the English glass registration lozenge (or Victorian glass registration 'diamond' date mark as it sometimes called) that you are translating belongs to by confirming in which corners the numbers and letters are in reference to the two lozenge diagrams above. Then select the relevant characters from the drop-down boxes for each corner of the lozenge. After that, just click the 'Search For Registration' button and a window will appear containing the result of the antique glass registration lozenge translation.
The translator contains all glass design registrations for the period 1842 too 1883. So, if no registration result is returned then it means the combination of characters that were selected was incorrect (See 'Wildcards' below for further options). NOTE: British registered glass designs are always class III as shown at the top of each lozenge above.
If you have no registration to hand, try translating the glass registration lozenge example shown here on the right.
Often an actual glass registration lozenge has a hard to read character, so this translator includes the facility to use a 'wildcard' on any ONE of the day, month, year or parcel selections. To use a wildcard to possiby obtain a search result for a registered design, simply select the "?" character at the bottom of any one of the drop-down character lists.
