STRONG AS CAST IRON

BRITAIN'S DISCOVERY FOR' WAR INDUSTRIES After two years' continuous research, Great Britain is to-day able to introduce pottery into many new fields of British industry tot take the place of metals, alloys, glass, rubber and "wood on the use of which restrictions have inevitably been placed in war time. High grade chemical stoneware comparable with grey cast iron in mechanical' strength can now be used in place of metal for pipe lines and also for packing purposes either in relatively small units or in bulk. These novel ceramic wares have certain advantages over the materials in former use. They resist rust and contamination; they can be turned into an almost unlimited number of shapes and sizes, and they are proof against all corrosive chemicals except hydrofluoric acid and hot, strong caustic alkalis. I The new pottery, is, moreover, prepared with such scientific thoroughness, and fired in the kilns at such a high temperature, that, in compression strength it resembles metals rather than the fragile china or earthenware ornaments of the home. [ NeAV applications of ceramic materials have also been introduced in recent months to textiles, rayon, paper-making, printing, soap, perfumery, cosmetics brewing and food manufacture industries and to many branches of the chemical, metallurgical and electrical industries.
