... deg. C.; but in two tests out of ten he obtained temperatures of about 160 deg. C. To determine the actual temperature of the calcium carbide itself, he scattered amongst the carbide charge fragments of different fusible metallic alloys which were known to melt or soften at certain different temperatures. In all his ten tests the alloys melting at 120 deg. C. were fused completely; in two tests other alloys melting at 216 deg. and 240 deg. C. showed signs ... — Acetylene, The Principles Of Its Generation And Use • F. H. Leeds and W. J. Atkinson Butterfield
