Crystallography is the science that studies the atomic structure and related properties of materials and is at the forefront of advances in many fields of science. Zometool’s Crystallography kit allows you to build all 7 possible crystal system structures simultaneously or all 14 Bravais lattices. Crystallography is an exciting field which underpins the development of practically all new materials. Teachers can build models for in-class demonstrations. Includes colorful, thoughtfully written and illustrated instructions that open up into a beautiful 22’x14äó (56x36cm) poster. An inspiring introduction to the wonder of crystals. All components are 100% made in the USA, inter-compatible, and come with a lifetime manufacturers warranty. Zometool is the construction set that kids and Nobel Prize winners get hooked on.
