A production that has distinguished the Manifattura Ginori since the second half of the 19th century is that of laboratory porcelain. Beakers with spouts, chemical-mechanical filters for purifying water, common and filtering funnels, mortars and pestles, ladles that are perforated or with pouring spouts, and other items used in research or in the chemical and pharmaceutical industries were made from a fire-resistant ceramic material, which was particularly suitable because it is heat-resistant, mechanically stress-resistant, and resistant to the attacks of acids and bases.
On the cover of this catalogue from the Museo Ginori Archive a spherical-bottom capsule with spout, a filter, and a cylindrical tube made of laboratory porcelain are shown. In the upper right appears the trademark Pasta Euclide, enclosed within a distillation flask placed over a flame, and the inscription Richard-Ginori in block letters below. This trademark was registered by the Società Ceramica Richard-Ginori in Milan on December 3, 1940. For this reason, it is possible to date the specimens showing this special mark to the 1940s.
