Overall: 7 3/4 x 4 1/2 in. ( 19.7 x 11.4 cm )
Metal calipers with rounded arms tapering to a point, 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.
