Seth Thomas Adamantine Clocks
Seth Thomas made clocks in marble cases for a short time, from 1887 to about 1895. They also made clocks in iron cases finished in black enamel, from 1892 to about 1895. Seth Thomas is well known for their “Adamantine” black mantel clocks, which were made starting in 1882. Adamantine is a celluloid veneer, glued to the wood case. Adamantine veneer was made in black and white, and in colored patterns such as wood grain, onyx and marble.
Adamantine veneer was developed by the Celluloid Manufacturing Company of New York City, and was covered by U.S. Patent number 232,037, dated September 7, 1880. Seth Thomas Clock Company purchased the right to use the Adamantine veneer in 1881.
