As is known, the Debye camera serves as a device in which X-rays are taken in monochromatic rays of finely crystalline and amorphous bodies. As a result of petrographic studies of the cast rock, the following information was obtained: a) the most important mineral components are: magnetite, olivine, plagioclase and a mineral whose composition is close to Ca₃Mg₂Si₆0₁₉, b) the main structure of the cast rock (mainly cast basalt). The results of physical and chemical research consist of a) identification of artificial mineral components of cast rock: ecstatite, diopside, forsterite and acortite, their physical and chemical properties were studied under casting conditions, b) heating Endell Microscope from Leitz - reconstructed for special research work to determine high-speed and crystallizing properties of crystalline elements of cast rock. X-ray laboratory of the Fedorov Institute at the Leningrad Mining Institute.
