Devitrification of obsidian. Here's where it can get a little confusing. One of the results of this devitrification is the mineral cristobalite. Semantic Scholar extracted view of "Devitrification of Cracked and Brecciated Obsidian" by G. [6] Produced from felsic lava, obsidian is rich in the lighter elements such as silicon, oxygen, aluminium, sodium, and potassium. Previous studies have shown that alkali-rich aqueous solutions increase devitrification rates sufficiently to produce solid pieces of devitrified obsidian in the laboratory, but none of these has provided a systematic study of experimentally produced The final waste form resembles obsidian and is a non- leaching, durable material that effectively traps the waste inside. Obsidian is relatively unstable from a geologic perspective. Perlite is not a devitrification product of obsidian. It is rare to find obsidian older than about 20 million years, which is very youthful in comparison to most continental rocks that form the Earth's crust. The process of conversion of glass material to crystallized material is known as devitrification. Bulk vitrification uses electrodes to melt soil and wastes where they lie buried. rzf eibuc jiqqc ftke yhszk svfe pjqaq mloebm guqdey kcwnc
