The pages are in good condition for their age.Author: Carl Immanuel LöscherEdition: 1stThe Description of Crystallizations, published in 1801, is a significant work in mineralogy. It discusses crystallizations according to their basic forms, such as cubes, prisms, pyramids, and tables, as well as variations of these basic forms. The book was written by Carl Immanuel Löscher, a former mining master for the Counts of Thun, and contains 96 pages and 6 copper plates. It is a valuable document that conveys the fundamentals of crystallography and crystallization in mineralogy. 

Three-dimensional models - very precisely constructed of wooden balls in different colors according to the elements they represent, and linked by a lattice of metal rods. They provide excellent means of illustrating the structure of the space lattice in molecules and compounds. Even in the most complicated models the atomic planes, the characteristic symmetry functions and the optical properties can easily be recognized.30 x 30 cm

15 natural crystalsin compartmented collection boxThe collection contains 4 cubic, 2 hexagonal, 2 tetragonal, 2 rhombic, 4 monoclinic, and one triclinic crystals and provide an easy introduction to the complicated laws of crystallography. The interpendence between physical, chemical, and crystallographic properties can be demonstrated on the natural crystal. Our collection contains all relevant information such as the MILLER indices of the most important crystal faces. All specimens are numbered according to a check list and provided with individual labels. The collection is housed in a compartmented collection box.
