2 Ravenscroft, George
[br]b. 1632 Alconbury, Huntingdonshire, Englandd. 7 June 1683 Barnet, Hertfordshire, England[br]English inventor of lead-crystal glass.[br]George's father James was a successful lawyer and merchant, engaging in overseas trade.A devout but necessarily circumspect Catholic, James sent his sons to the English College at Douai, now in northern France. Leaving there in 1651, George began to learn his father's business and spent some fifteen years in Venice. He took an increasingly important part in it, doubtless dealing in Venice's leading products of lace and glass. By 1666 he was back in England and, perhaps because the supply of Venetian glass was beginning to decline, he started to manufacture glass himself. In 1673 he set up a glassworks in the Savoy in London and succeeded so well that in the following year he petitioned the King for the grant of a patent to make glassware. This was granted on 16 May 1674, stimulating the Glass Sellers' Company to enter into an agreement with Ravenscroft to buy the glassware he produced. Later in 1674 the company allowed Ravenscroft to establish a second glasshouse at Henley-onThames. At first his ware was beset with "crizzling", i.e. numerous fine surface cracks. The Glass Sellers probably urged Ravenscroft to cure this defect, and this he achieved in 1675 by replacing crushed flint with increasing amounts of lead oxide, rising finally to a content of 30 per cent. He thereby obtained a relatively soft, heavy glass with high refractive index and dispersive power. This made it amenable to deep cutting, to produce the brilliant prismatic effects of cut glass. At about the same time, the Duke of Buckingham, a considerable promoter of the glass industry, agreed that Ravenscroft should manage his works at Vauxhall for the making of plate glass for mirrors. Ravenscroft terminated his agreement with the Glass Sellers in 1678, the date of the last evidence of his activities as a maker of crystal glass, and the patent expired in 1681. His new glass had immediately rivalled the best Venetian crystal glass and has been a valued product ever since.[br]Further ReadingR.F.Moody, 1988, The life of George Ravenscroft', Glass Technology 29 (1):198–210;Glass Technology 30(5):191–2 (additional notes on his life).LRD -

17 Neri, Antonio Ludovico
[br]b. 29 February 1576 Florence, Italyd. 1614 Florence, Italy[br]Italian glassmaker.[br]Neri entered the Church and by 1601 was a priest in the household of Alamanno Bertolini in Florence. There he met the Portuguese Sir Emanuel Ximenes, with whom he shared an interest in chemistry. The two later corresponded and the twenty-seven letters extant from Ximenes, who was living in Antwerp, are the main source of information about Neri's life. At the same time, Neri was working as a craftsman in the Medici glasshouse in Florence and then in their works at Pisa. These glasshouses had been flourishing since the fifteenth century with the help of Muranese glassmakers imported from Venice. Ximenes persuaded Neri to spend some time with the glassmakers in Antwerp, probably from 1603/4, for the correspondence breaks off at that point. A final letter in March 1611 refers to Neri's recent return to Florence. In the following year, Neri published the work by which he is known, the L'arte vetraria, the first general treatise on glassmaking. Neri's plan for a further book describing his chemical and medical experiments was thwarted by his early death. L'arte belongs to the medieval tradition of manuscript recipe books. It is divided into seven books, the first being the most interesting, dealing with the materials of glassmaking and their mixing and melting to form crystal and other colourless glasses. Other sections deal with coloured glasses and the making of enamels for goldsmiths' use. Although it was noted by Galileo Galilei (1564–1642), the book made little impression for half a century, the second edition not appearing until 1661. The first Venice edition came out two years later, with a second in 1678. Due to a decline in scientific activity in Italy at this time, L'arte had more influence elsewhere in Europe, especially England, Holland and France. It began to make a real impact with the appearance in 1662 of the English translation by Christopher Merrett (1614–95), physician, naturalist and founder member of the Royal Society. This edition included Merrett's annotations, descriptions of the tools used by English glassmakers and a translation of Agricola's short account of glassmaking in his De re metallica of 1556. Later translations were based on the Merrett translation rather than the Italian original. Ravenscroft probably used Neri's account of lead glass as a starting point for his own researches in the 1670s.[br]Bibliography1612, L'arte vetraria, 7 vols; reprinted 1980, ed. R.Barovier, Milan: Edizioni Polifilo (the introd., in Italian, England and French, contains the most detailed account of Neri's life and work).LRD
