Successful Picture On Glass: Continuous Tanks.—The first continuous tank for melting glass was built in 1885 at Pough-keepsie, N. Y., and the first successful window glass tank was made in Jeanette, Pa., in 1888. The tanks used for making plate glass are five feet deep, 30 feet wide, and 125 feet long, with a capacity of up to 1,400 tons of glass. Tanks used for making window glass are somewhat longer, not so much for the purpose of holding more glass but to give the glass more time for fining and cooling to a workable temperature.
The exposure was said to have lasted some eight hours; during that time the sun in its travels from east to west lighted both sides of the buildings, destroying the modeling. The image is laterally reversed: left and right are transposed, as in a mirror. The place, which is of pewter, is not dated, but external evidence points to its production in 1827. A far more successful picture on glass, of a Table set for a meal, was presented to the French Society of Photography in 1890 by a member of the Niepce family.
In fact, selling is so important that many photographers have found it satisfactory to take salesmen into business with them as full partners. One of America's leading commercial and advertising photographers is highly successful almost altogether because of his sales ability, and the actual picture-taking is done by others in his organization, although the picture credits always carry his name. |
