Such articles are usually malle from sheet nietnl on aeeouni of the impossibility.' of producing y. uctieal castinffi. l. have (linen-tiered thai; phosphorus applied to l.. l metal while the latter ie in e. molten suite in the mold will improve its fluidity or flew, thereby Causing it. lo proi'lerlg.' and completely-lill the mold.
