Wedge-shaped microscopic preparations of the simplest design
Abstract
The goal of these preparations is to enable, in all cases where laboratory crystals are obtained from supersaturated solutions, an optical study to be carried out in parallel with goniometric measurement, with the most precise possible orientation of the axes of the optical ellipsoid. Until recent years, I used homemade preparations, assembling them from offcuts of cover glasses, cut and glued onto a slide in such a way as to create the required wedge-shaped space for crystallization. I have now settled on a relatively simple and, for research purposes, very convenient type, which is fully clarified by the attached plan and section of the microscopic preparation (see the article).
