These beakers usually do not have a flat scale. Before World War I, glass producers in the United States had difficultly competing with German Laboratory Glassware manufacturers because laboratory glassware was classified as educational material and was not subject to an import tax. Alternatively, a beaker may be covered with another larger beaker that has been inverted, though a watch glass is preferable. Fritted glass is finely porous glass through which gas or liquid may pass. Materials[ edit ] Beakers are commonly made of glass today usually borosilicate glass [2] , but can also be in metal such as stainless steel or aluminium or certain plastics notably polythene , polypropylene , PTFE.
