This form of marbled or agate ware was probably introduced at Wedgwood before 1768.  Josiah Wedgwood enthusiastically refers to this form of decoration in a letter dated 3rd January 1768:

'There is much sin to be committed in the Marble way, as you will guess by the patterns. L^d have mercy upon our old Stock say I!'
