Lambeth has been a seat of pottery manufacture from an early period. In mediæval times the characteristic brown-ware pitchers, pans, tygs, &c., were made; and, later on, at this place was quite a colony of makers of Delft ware, who in turn gave place to stoneware manufacturers. China, too, appears to have been made at Lambeth from perhaps 1760, or thereabouts. It is recorded that in the middle of the seventeenth century the Delft ware manufacture commenced; but it is not unlikely that Rous and Cullyn, some years earlier, here established themselves in the making of “stone potts, stone jugs, and stone bottels,” for which they received a patent in 1626.[50] It is conjectured, and with some probability, that one of the Delft ware makers at this place was John Ariens Van Hamme, a Dutchman, who had come over from the Hague under the encouragement of our ambassador, who, as has already been shown,[51] took out a patent in 1676 for the “art of makeinge tiles and porcelane and other earthen wares, after the way practiced in Holland,” and who, with his staff of workmen, probably formed the nucleus of what was afterwards a nest of potters, comprising, according to the “History of Lambeth,” no less than twenty manufactories. In 1693 a trial took place in the Court of Exchequer concerning some parcels of potter’s clay which had been seized by the Custom House officers, under pretence that it was fuller’s earth. In this trial five London potters, William Knight, Thomas Harper, Henry De Wilde, John Robins, and Moses Johnson, gave evidence in favour of the clay being potter’s clay. There is nothing in the record of this trial to identify any of the five potters therein named with Lambeth; but the probability is that some of them belonged to that place. One of them, William Knight, was undoubtedly the “William Knight of the parish of St. Buttolph Without, Aldgate, London, Pottmaker,” concerning whom I give, from the original deed in my possession, some particulars under the head of “Aldgate;” some of the others were, I believe, of Lambeth. The account of the trial has been printed by my friend, Mr. Reeks, in the “Catalogue of the Museum of Practical Geology,” and is so interesting that I here reproduce it entire. _A Brief Account of the Evidence given on behalf of_ Edmund Warner, _at a_ Tryal _had at the Bar the 24th of_ November, 1693, _before the Four Barons of the_ Exchequer, _relating to a Parcel of_ Potters Clay, _seized by the_ Custom-House _Officers, under the pretence of it’s being_ Fullers Earth.
