About Calcium
Calcium is a census-designated place (CDP) in Jefferson County, New York, United States. The population was 3,573 as of the 2020 census. The CDP is in the town of Le Ray and includes the hamlets of Calcium and Sanfords Four Corners.
The town was renamed Calcium in 1911 at the request of local inventor Madison Cooper after the calcium chloride used in his patented refrigeration plants.
Historic landmarks include the stone house at the intersection of State Route 342 and County Route 138 that once served as the post office for the area, and the Calcium Community Church at the same intersection. The church was built in 1853 by a group of at least three different denominations, including Methodist Episcopal, Christian, and Unitarian. The building was shared by these and various Christian groups over the years, and remains a community church today.
