3 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 -
4 Guinand, Pierre Louis
SUBJECT AREA: Photography, film and optics[br]b. 20 April 1748 Brenets, Neuchâtel, Switzerlandd. 13 February 1824 Brenets, Neuchâtel, Switzerland[br]Swiss optical glassmaker.[br]Guinand received little formal education and followed his father's trade of joiner. He specialized in making clock cases, but after learning how to cast metals he took up the more lucrative work of making watch cases. When he was about 20 years old, in a customer's house he caught sight of an English telescope, a rarity in a Swiss mountain village. Intrigued, he obtained permission to examine it. This aroused his interest in optical matters and he began making spectacles and small telescopes.Achromatic lenses were becoming known, their use being to remove the defect of chromatic aberration or coloured optical images, but there remained defects due to imperfections in the glass itself. Stimulated by offers of prizes by scientific bodies, including the Royal Society of London, for removing these defects, Guinand set out to remedy them. He embarked in 1784 on a long and arduous series of experiments, varying the materials and techniques for making glass. The even more lucrative trade of making bells for repeaters provided the funds for a furnace capable of holding 2 cwt (102 kg) of molten glass. By 1798 or so he had succeeded in making discs of homogeneous glass. He impressed the famous Parisian astronomer de Lalande with them and his glass became well enough known for scientists to visit him. In 1805 Fraunhofer persuaded Guinand to join his optical-instrument works at Benediktheurn, in Bavaria, to make lenses. After nine years, Guinand returned to Brenets with a pension, on condition he made no more glass and disclosed no details of his methods. After two years these conditions had become irksome and he relinquished the pension. On 19 February 1823 Guinand described his discoveries in his classic "Memoir on the making of optical glass, more particularly of glass of high refractive index for use in the production of achromatic lenses", presented to the Société de Physique et d'Histoire Naturelle de Genève. This gives details of his experiments and investigations and discusses a suitable pot-clay stirrer and stirring mechanism for the molten glass, with temperature control, to overcome optical-glass defects such as bubbles, seeds, cords and colours. Guinand was hailed as the man in Europe who had achieved this and has thus rightly been called the founder of the era of optical glassmaking.[br]Further ReadingThe fullest account in English of Guinand's life and work is 'Some account of the late M. Guinand and of the discovery made by him in the manufacture of flint glass for large telescopes by F.R., extracted from the Bibliothèque Universelle des Sciences, trans.C.F.de B.', Quart.J.Sci.Roy.Instn.Lond.
