Abstract
In brief reports of the 1st issue of vol. I of the "Notes of the Mining Institute" (p. 83), I reported on some experiments on the growth of spheres (hemispheres) prepared from crystals of chrome and potassium alum. Similar experiments were carried out with crystals of rock salt (NaCl) from Stassfurt. A welded piece of such salt was ground into a hemisphere with a diameter of 10 m.m. with a central plane (100) and glued with wax onto a glass hemisphere of the same diameter.
