"The Recipe for Making Diamonds"

Asserts that the pure carbon of which diamonds consist is '"perfectly transparent to the Röntgen rays"—which supply "an easy and infallible test for genuine diamonds"'. Goes on to describe the method of manufacturing diamonds through the liquefaction of carbon developed by Ferdinand-Frédéric-Henri Moissan, which is 'one of the triumphs of high-temperature chemistry' and was made possible only by the 'invention of the electric furnace' which can reach temperatures of 'near 3,600 deg. C.' and requires the use of 'boiling lead' as a 'cooling bath'. The largest diamond manufactured so far, however, was 'only one-fiftieth of an inch across, and within three months broke up'.
