Overall: 6 1/4 x 1 in. ( 15.9 x 2.5 cm )
stamped: on arm of calipers: "Wm JOHNSON / NEWARK, N.J."
Metal calipers, used for making blown glass vessels.
This pair of calipers is among a group of sixteen tools used by Maurice Kelly (1879-1963), a glass blower who worked at Tiffany Studios from 1904 to 1918, as well as Quezal (1901-1903) and Durand Art Glass (1918-1920s). The tools, along with photographs and documents now housed in the NYHS library, were consigned to auction by Kelly's grandson and were acquired by NYHS. Included among the documents is a wage book recording Kelly's steady increase in pay from $19.25 to $35 per week.
