The results of studies of the effect of natural deformation changes in milky-white quartz on its trace element composition and properties of deposited glasses are presented. It is shown that various stages of enrichment have a significant effect on the content of elements in quartz grains and are subsequently inherited by glass. It has been established that impurities are not only a source of defects in glass, but also increase the speed of the crystallization process, improving the quality of welded glasses.
Korekina et al. (Wed,) studied this question.
