Coplay Cement Company Kilns . Lehigh County . Plein Air . Watercolor . 12" x 16"
... these 9 towering remnants are all that remain of the factory and vertical kilns that were in use, by the Coplay Cement Company, from 1893 to 1904, before they quickly became obsolete in a rapidly expanding construction industry. These vertical kilns, originally 90-feet tall, were built by David O. Saylor, who refined the process and opened the first Portland Cement Plant in 1871 at Coplay... and were a major improvement over bottle and dome kiln technology... but by 1904, they were shut down due to the extraordinary efficiencies provided by the newly developed rotary kiln. East Central Pennsylvania is considered the birthplace of Portland Cement in the America's, competition was fierce and in short order, there were enough cement plants in operation, throughout the Lehigh Valley to supply 75% of all the cement needs for the entire United States. These kilns stand within the current bounds of the Saylor Park Industrial Museum and were added to the National Register of Historic Places in 1980. Learn more... Ever Since the Fire Went Out:
