This philatelic corner is a tribute to pyrite, a brilliant mineral with attractive geometric shapes that has always excited collectors and geologists worldwide and whose relevance has been captured on the stamps of many countries.

The focus of this note is Fray Martín de Porres Velásquez, the patron saint of pharmaceutical chemists in Peru, which was portrayed in a Peruvian stamp.

The stamps of the Peruvian Exhibition in Paris of 1958 and the chemical elements present in them

Introduction to the Use of Philatelic for Teaching ChemistryThis article offers an introduction to the world of chemistrythrough its representation in postage stamps and other philatelicmaterials from many countries. Besides famous chemists orNobel prize winners in chemistry, there are stamps showingatoms, molecules, minerals, symbols and chemical formulas,the periodic table, laboratory equipment, and various aspectsof chemical industry. Such stamps can easily be used to portrayseveral themes for teaching chemistry at all levels, or can beused together with anecdotes or historical details, for example,to make technical presentations much more attractive
