The Effect of the Continued Remelting of Cullet in Sillimanite and Fireclay Vessels

JSGT 1929 V13 T296-T303

In previous papers,* we have described the results of investigations on the melting of soda–lime–silica and potash–lead oxide–silica glasses from mixtures made up of varying proportions of batch and cullet. The influence of the proportion of cullet was ascertained on the rate of melting and refining as well as on the working properties, and the conclusion was reached in all cases examined that there was a shortening of the working range of the glass as the proportion of cullet to batch was increased. This phenomenon could not clearly be ascribed to continued loss of alkali content, or to other appreciable changes of composition such as increase in iron oxide content.
