Carte de visite photograph by Sarony, Hill & Thrupp of Robert Lucas Chance of Chance Bros & Co (1832-1981), a firm of glas manufacturers in Smethwick, Birmingham. Chance bought the Spon Lane Glasworks of the British Crown Glas Company in 1824, and gave his name to the company when he was joined in 1832 by his brother William. In 1834 Chance introduced the IMPROVED CYLINDER SHEET technique using a German proces which gave finer quality and larger panes. This glas was used to glaze Joseph Paxton's Crystal Palace in London. The proces was used until early in the 20th century.
