Description
V-shaped glass with pouring lip and foot, suitable for chemical experiments. The form, sometimes termed a graduated measure glass, is associated with Thomas Clark (1801-1867), a Scotsman who, in 1833, became professor of chemistry at Marischal College in Aberdeen. The sides of this example are graduated to 8 oz. and 250 cc.
Brown University opened a new chemistry building in 1862, in response to the growing “demand for improved facilities for instruction in this department of learning, intimately connected as it is with manufacturing interests and industrial pursuits.” This test glass was probably acquired at that time.
