Heat That Makes Iron Boil Like Water I FOR somo yearn past scientific men have been 6trlving to produce pro-duce heat fiercer than any tern-peraturo tern-peraturo of which we have experience experi-ence In ordinary life. The greatest heal over developed by the agency of man wan obtained by Sir Audrow Noble, who exploded cordite In cloeod vessels, eo that a prossure of fifty tons to tho square Inch was registered, and a dogreo of heat never previously recorded. The highest tomperaturo reached In fuel furnace for practical purpose pur-pose Ib between 1.700 and 1.S00 degrees de-grees centigrade, and at such a heat fireclay and porcelain are melted. Then wo come to the flomo fed with hydrogen and oxygen, or oxygon nda coal gas; by these meanB a temperature of 2,000 degrees centigrade centi-grade may be obtained. A new Industry solely dependent upon the employment of great heat Is that of melting quartr. This mineral, min-eral, fused by tho oxy-hydrogaa flame, is converted Into tubes and llnsko and other vessels for chemical chemi-cal purposes. Theso veseels arc absolutely ab-solutely Inert, and may be heated hundreds of degrees higher than is possible with glass; thoy may also be plungod at auch heat into cold Wfttw .ulthP.Uj Injury - It has been discovered that by flH whirling a centrifugal wheel at high velocity In the combustion-chamber of a furnace the nitrogen ia cast to Hl ono side, while the oxygen Is ton- 9L contrated, and in this way a bright- 11 er fiamo and greater heat aro ob- IH talncd. A similar appliance used flflfl during tho combustion of coal In a furnaco enabled a firm of paper- . jB makers to savo twenty-seven per cent of their coal hill by tho cllmi- Bl nation of tho hydrogen gas formod IHfl in combustion. imH But most remarkable- of all tho phases of tho utilization of extreme heat is tho discovery of tho welding material known us thermit Ths HH inventor discovered' that aluminium Hflfi Is very much attach od to oxygen.

A small Sliffj quantity of magnesium filings was ffiMj placed on top of tho mixture and n 9SBh storm-match applied, and immedl- aHTB ately a mass of molten iron was HHIwl seen boiling at a tcmporature of IBM 8,000 degrees ccntigrado much ViR higher than any temporature In or- 3?S dlnwr 99.
