Be aware that another mark used on ornamental pieces between 17 was “Wedgwood & Bentley” appearing in script. Another rare mark is “Wedgwood & Sons,” which would date the piece to 1790. The inclusion of a number on pieces marked Wedgwood & Bentley refers to the number of the catalog the item first appeared in.
If you see this kind of mark, the piece predates 1780.
Other marks used by the Wedgwood & Bentley partnership include the names appearing in both upper and lower case or all lower case, followed by a period.
These marks date Wedgwood pieces to the years between 17. The Wedgwood family began using a 3-letter code to indicate the month in which the piece was made, the potter that made it and the year of manufacture, in that order.

Wedgwood had introduced a different type of stoneware called black basalt a decade earlier.
