THERMO, TEXAS. Thermo, on Farm Road 1870 and the Louisiana and Arkansas Railway, five miles east of Sulphur Springs in eastern Hopkins County, was founded around 1900. A brick manufacturing plant was established in 1910. The community was originally known as Crush, after a large rock crusher near the townsite. The rock was used for construction of railroad lines. The town's name was later changed to Thermo, for the Thermo Fire Brick Company, which produced fire-resistant brick. In the mid-1930s the community had the factory and a number of houses. In the late 1980s the factory was still in operation. The community was still listed in 1990.
