Inscription
An innovative tile and abrasives manufacturer, founded by the Robertson family of ceramic artisans in 1890, operated here until 1982. It was notable for craze-free pure white tiles, its efficient single-fire method, and an on-site quality control lab. Featured at the 1907 Jamestown Exposition, RATC ceramic mosaic tiles were among the first in the US to line an indoor swimming pool.
In the 1950s, Robertson tiles were installed in most original Levittown homes.
