An experimental flotation kiln was built into the face of Asham Quarry in 1928. In 1927 the chemist Geoffrey Martin had patented a kiln designed to enable cement to be manufactured more cheaply.Geoffrey Martin, British Patent No. 276.066 (application date 17 May 1926; complete acceptance date 17 August 1927) The experimental kiln to the patented design was constructed by hand. The experiments lasted three months in late 1929.R. G. Martin, 1992: "Experimental Cement Shaft Kiln at Beddingham", Sussex Industrial History pp. 21–35. The kiln was demolished when the quarry was converted into Beddingham landfill site.
