The goal of our synthetic experiments was to artificially obtain individual components of stone casting in a well-individualized form and in sufficiently large quantities. We had to synthesize, firstly, those minerals that were determined by petrographers during microscopic studies of stone castings and, secondly, those minerals whose presence in the castings can only be assumed. The latter could be present in the form of microliths and not amenable to optical determination, but could be detected during X-ray studies of stone castings. The minerals we synthesized had to be subjected to X-ray examination in order to obtain standard Debyegrams necessary for decoding the Debyegrams of stone castings. In accordance with the task, the synthesis method was also chosen, namely the method of crystallization of minerals from the corresponding melts.
