Dating wedgwood jasper
If a piece is modern/vintage, ie: 1908-present date.Usually the marks to the reverse of any Jasper Ware piece will be Wedgwood, Made in England.The marking that really tells the tale though is the “57.” Like many potteries, Wedgwood used a date code system on its pieces, the one used on urn this was introduced circa 1929-30, using the last two digits of the year the piece was made. The date code on this one—“57” —indicates this urn is certainly not an antique, as its date of production being 1957.
The first was in 1840-1841, and is very rarely found.
The second period was from about 1905 until the mid 1920's.
The best way to contest this form of deletion is by posting on the image talk page.
Jasperware was originally developed by Josiah Wedgwood during the mid-1700s and took advantage of new decorating trends, notably, in this case, copies of pieces found by early archeologists digging Greek and Roman ruins.
It can also appear on later pieces, but other indications will help to place these pieces in the correct period.
: The name of the factory was added during two periods.
The exceptions to the rule for this, are smaller objects, like thimbles, and other miniatures. I don't have a sample to hand for you, but it is separated, and not a uniform stamp like the one displayed above.
These most often carry Wedgwood England, purely because of the size of the item in comparison to the stamp. The letters accompanying the Wedgwood England for items dating between 1891-1908 are a dating code, which I will enter into shortly.
According to Reilly all black basalt made from 1769-1780 was either unmarked, or had this mark; however this is by no means certain; see the following paragraph.
There is evidence to be found in Wedgwood's correspondence that the usefulwares factory was still making basalt tea sets during the Wedgwood & Bentley period (1769-1780) and marking it with this mark.
Pre 1891 There was a three letter dating code in place. Those three letters would represent the month, the potter, and the year in that order. This wasn't foolproof for dating purposes as it did overlap, and for certain letters, there are two possible dates. Usually accompanied by other potter markings and a single letter.
