Mr Pell produced Bag which contained Potters' Sand , which formerly he had been desired to procure , upon a Discourse about the advancing our English Potters Art , that it might equall , (at least that of Germany , if not) the old Roman Bakers of Sepulchral Urnes : Which then gaue occasion to Speak of our English Materials , and our varieties of Earths, Clays and Sands : upon which Mr Pell related to the Company , that in Sussex , about 27 years since , he had seen a Bricklayer make a new Oven, wherein he observed an unusal Bottom , which the Workman had promised to make without Gaps and Chinks , as of one Stone , and therefore better , than if he should use Bricks , or any Sort of Paving Tyles : To which end , having brought a Sufficient quantity of Sand , (which as Mr Pell remembred , looked Blackish , as if it had been dirty ) he [crossed out; showedd] strawed it upon the rough bottom, of the Oven, and then for want of a flat hammer , took an iron wedge (made to cleaue wood withal) and with the flat end of it , did knock the Sand , and beat it close into a smooth floor, which being done, and the Oven finished, he, after the usual manner, did put wood into it and anneal it . After the Oven was cold, the Bottom of it seemed Solid and firme, and such as he had undertaken to make it . Nor did Mr Pell remember, that he saw any flaw in it a year after, though it had been used for baking, it might be every week.
Upon this Relation , some of the Company suggesting, that this Sand might be capable of more noble uses , than for Ovens : and that one might, perhaps, find it usefull for Vitrification ; or, at least , some untransparent fusion. The Relator was desired to cause some of that Sand to be brought hither, which came accompanied with a letter of one Mr Nicholas Gildrege of Eastborne, dated 29 June 1663 giving this further information , that the Sonne of the forementioned Bricklayer , called Carpenter had told him that the way to use, was, to beat it long with Hammers, till it becomes so firme and compact that they can pare it smooth eith their Tooles, and that then the great heat of the fier will harden it into a stone, But the Author of the Letter, addeth, that his usual Mason , one Rosom, had told him , he never Saw any Oven well made with it , but that he saw a Carpenter's father make one at Crowlinck , which seemed, when in parte and after paring , to be very like to doe well ; and as he thought Rosam said also , that after nealing too, it looked firme, yet the first or second time it was use it mouldered all up againe, and he was faine to bottom the oven with bricks . The Author of the letter , offered to send the whole quanity of this sand, which he had in his house, viz. neer a Gallon , if it should be desired . Mr Pell had the thanks of the Company , and himself and Dr Goddard were desired to Examine this sand, and to make some tryalls of it.
