“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. “THOMAS SHAW, “SAMUEL GILBODY.” “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. “ELLIS CUNCLIFFE, “SPENCER STEERS, “CHARLES GOORE. “Addressed to Charles Pole, Esq., in London.”
