Usage conditions apply
This V-shaped glass with pouring lip and foot was designed for chemical experiments. The form is associated with Thomas Clark (1801-1867), a Scotsman who, in 1833, became professor of chemistry at Marischal College in Aberdeen. By 1841, examples could be had from Richard Griffin & Co., apparatus dealers in Glasgow.
