Triangular table: chemistry puzzle and teaching device

摘要

A puzzle apparatus for the study of chemistry and its history and based upon the Zmaczynski equilateral triangular model of the periodic table of the chemical elements. A triangular shaped base is used as a puzzle base and it is shaped and sized in order accommodate rhombohedron shaped pieces that fit into the base and form an overall triangular shape when the puzzle is complete.
