... thus affect properties in similar ways. Traditionally, the structural role of a component in an oxide glass is designated as that of a glass former, a modifier, or an intermediate. Glass formers are those oxides that readily form a glass on their own, such as SiO 2 , B 2 O 3 , and GeO 2 . Modifiers...

.... For thin-wall castings, such specimens provide more reliable test results than do specimens that are separately cast. In many castings whose designs incorporate cored holes, the shifting of cores as the castings are poured can reduce wall thickness to the point where complete filling of the mold...
