“Taken and sworn at Liverpoole, in the county of Lancaster, the second day of August, one thousand seven hundred and fifty-six, before William Statham, a Master Extraordinary in Chancery.”

“We, Alderman Thomas Shaw and Samuel Gilbody, both of Liverpoole, in the county of Lancaster, clay potters, whose names are hereunto subscribed, do hereby humbly certifye that we are well assured that John Sadler and Guy Green did, at Liverpoole aforesaid, on Tuesday, the 27th day of July last past, within the space of six hours, print upwards of 1,200 earthenware tiles of different colours and patterns, which is upon a moderate computation more than 100 good workmen could have done of the same patterns in the same space of time by the usual painting with the pencil. That we have since burnt the above tiles, and that they are considerably neater than any we have seen pencilled, and may be sold at little more than half the price. We are also assured the said John Sadler and Guy Green have been several years in bringing the art of printing on earthenware to perfection, and we never heard it was done by any other person or persons but themselves. We are also assured that as the Dutch (who import large quantities of tiles into England, Ireland, &c.) may by this improvement be considerably undersold, it cannot fail to be of great advantage to the nation, and to the town of Liverpoole in particular, where the earthenware manufacture is more extensively carried on than in any other town in the kingdom; and for which reasons we hope and do not doubt the above persons will be indulged in their request for a patent, to secure to them the profits that may arise from the above useful and advantageous improvement.

“Liverpoole, August 13th, 1756.

“Sir,

“John Sadler, the bearer, and Guy Green, both of this town, have invented a method of printing potters’ earthenware tyles for chimneys with surprising expedition. We have seen several of their printed tyles, and are of opinion that they are superior to any done by the pencil, and that this invention will be highly advantageous to the kingdom in generall, and to the town of Liverpoole in particular.

“In consequence of which, and for the encouragement of so useful and ingenious an improvement, we desire the favour of your interest in procuring for them his Majesty’s letters patent.

“Addressed to Charles Pole, Esq., in London.”

In the Mayer museum are found, among other invaluable treasures, some enamels on copper bearing impressions from copper-plates transferred to them, and having the name of “J. Sadler, Liverpl, Enaml,” and other examples of enamels and of earthenware with the names of “Sadler, Sculp.,” or of “Green.” Messrs. Sadler and Green appear to have done a very profitable and excellent business in the printing on pottery. The process was soon found to be as applicable to services and other descriptions of goods as to tiles; and these two enterprising men produced many fine examples of their art, some of which, bearing their names as engravers or enamellers, are still in existence. Josiah Wedgwood, always alive to everything which could tend to improve or render more commercial the productions of his manufactory, although at first opposed to the introduction of this invention, as being, in his opinion, an unsatisfactory and unprofitable substitute for painting, eventually determined to adopt the new style of ornamentation, and arranged with the inventors to decorate such of his Queen’s ware as it would be applicable to, by their process. The work was a troublesome one, and in the then state of the roads—for it must be remembered that this was before the time even of canals in the district, much less of railroads—the communication between Burslem and Liverpool was one of great difficulty. Wedgwood, however, overcame it, and having made the plain body at his works in Staffordshire, packed it in waggons and carts, and even in the panniers of pack-horses, and sent it to Liverpool, where it was printed by Sadler and Green, and returned to him by the same kind of conveyance. The works of Sadler and Green were in Harrington Street, at the back of Lord Street, Liverpool, and here they not only carried on their engraving and transfer-printing for other potters, but made their own wares, and carried on an extensive business. It was here that they printed ware for Josiah Wedgwood. Of this connection of Wedgwood with the Liverpool works, Mr. Mayer thus writes:—
