A production that has distinguished Manifattura Ginori since the second half of the nineteenth century is that of laboratory porcelain. Beakers with spouts, chemical-mechanical filters for purifying water, common and filtering funnels, mortars and pestles, perforated ladles or with pour spouts, and other items used in research or in the chemical and pharmaceutical industries were made from pyrophilic ceramic material, particularly suitable for use because it is heat-resistant, mechanically stress-resistant, and resistant to the aggression of acids and bases.
On the cover of this catalog preserved in the Ginori Museum Archive are depicted a spherical-bottom capsule with spout, a filter, and a cylindrical tube made of laboratory porcelain. 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 of Milan on December 3, 1940. For this reason, it is possible to date the specimens showing this special mark to the 1940s.
