12 Pattinson, Hugh Lee
SUBJECT AREA: Metallurgy[br]b. 25 December 1796 Alston, Cumberland, Englandd. 11 November 1858 Scot's House, Gateshead, England[br]English inventor of a silver-extraction process.[br]Born into a Quaker family, he was educated at private schools; his studies included electricity and chemistry, with a bias towards metallurgy. Around 1821 Pattinson became Clerk and Assistant to Anthony Clapham, a soap-boiler of Newcastle upon Tyne. In 1825 he secured appointment as Assay Master to the lords of the manor of Alston. There he was able to pursue the subject of special interest to him, and in January 1829 he devised a method of separating silver from lead ore; however, he was prevented from developing it because of a lack of funds.Two years later he was appointed Manager of Wentworth Beaumont's lead-works. There he was able to continue his researches, which culminated in the patent of 1833 enshrining the invention by which he is best known: a new process for extracting silver from lead by skimming crystals of pure lead with a perforated ladle from the surface of the molten silver-bearing lead, contained in a succession of cast-iron pots. The molten metal was stirred as it cooled until one pot provided a metal containing 300 oz. of silver to the ton (8,370 g to the tonne). Until that time, it was unprofitable to extract silver from lead ores containing less than 8 oz. per ton (223 g per tonne), but the Pattinson process reduced that to 2–3 oz. (56–84 g per tonne), and it therefore won wide acceptance. Pattinson resigned his post and went into partnership to establish a chemical works near Gateshead. He was able to devise two further processes of importance, one an improved method of obtaining white lead and the other a new process for manufacturing magnesia alba, or basic carbonate of magnesium. Both processes were patented in 1841.Pattinson retired in 1858 and devoted himself to the study of astronomy, aided by a 7½ in. (19 cm) equatorial telescope that he had erected at his home at Scot's House.[br]Principal Honours and DistinctionsVice-President, British Association Chemical Section 1838.

For their bronze coins the Greeks adhered to copper and tin till B.C. 400, after which they added lead. Silver is rare in Greek bronze coins. The Romans admitted lead into their bronze coins, but gradually reduced the quantity, and, under Calig., Nero, Vesp., and Domit., issued pure copper coins, and then reverted to the mixture of lead. In the bronze mirrors now existing, which are nearly all Etruscan, silver predominated to give a highly reflecting surface. The antique bronze had about 87 parts of copper to 13 of tin. An analysis of several objects has given the following centesimal parts: statua ex aere, Cic. Phil. 9, 6:II.simulacrum ex aere factum,

SUBJECT AREA: Metallurgy[br]b. c.1515d. 14 July 1579[br]English goldsmith and Assay Master of the Royal Mint who attempted to introduce brass production to England.[br]William Humfrey, goldsmith of the parish of St Vedast, was appointed Assay Master of the Royal Mint in 1561. At the Tower of London he assumed responsibility for the weight of silver and for production standards at a time of intense activity in recoining the debased coinage of the realm. Separation of copper from the debased silver involved liquation techniques which enabled purification of the recovered silver and copper. German co-operation in introducing these methods to England developed their interest in English copper mining, resulting in the formation of the Mines Royal Company. Shareholders in this government-led monopoly included Humfrey, whose assay of Keswick copper ore, mined with German expertise, was bitterly disputed. As a result of this dispute, Humfrey promoted the formation of a smaller monopoly, the Company of Mineral Battery Works, with plans to mine lead and especially the zinc carbonate ore, calamine, using it to introduce brassmaking and wire manufacture into England. Humfrey acquired technical assistance from further skilled German immigrants, relying particularly on Christopher Schutz of Annaberg in Saxony, who claimed experience in such matters. However, the brassmaking project set up at Tintern was abandoned by 1569 after failure to make a brass suitable for manufacturing purposes. The works changed its production to iron wire. Humfrey had meanwhile been under suspicion of embezzlement at the Tower in connection with his work there. He died intestate while involved in litigation regarding infringement of rights and privileges claimed from his introduction of new techniques in later lead-mining activities under the auspices of the Company of Mineral and Battery Works.[br]Further ReadingM.B.Donald, 1961, Elizabethan Monopolies, London: Oliver \& Boyd (the most detailed account).——1955, Elizabethan Copper, reprinted 1989, Michael Moon.JD -
