Principle

Gypsum can be used as versatile material, for example "prints" from different small objects can be built with gypsum. Such "negatives" can be filled with other materials which create the so called "positive". In this experiment students produce imprints of coins and examine how plaster molds can be produced and what applications are based on plaster molds.
