Saylor Cement Museum

In the Lehigh Valley rock suitable for hydraulic cement had been found near the present locations of Palmerton and Northampton when the Lehigh Canal was built. Mills to produce hydraulic cement were erected at these sites before the Civil War. It was against this background that David O. Saylor began his experiments for producing Portland cement. As had been true in Europe he learned that by burning certain limestone almost to a melting point, he produced the material which upon further refinement became Portland Cement.
