Handkerchiefs
As a glue-size refers to: (Malerläppchen, Pezette, Bezetta, Pezola, Pezzuole, Pezzuli or Peczola also) an ancient method of storage of water-soluble vegetable dyes.
They were created by coloring small cloth flaps with plant color extracts. These painters' cloths could then be used as coloring agents for artists when they were moistened with a little water. Travelers and painters of the 18th and 19th centuries, from S. Merian to G. Foster, Humboldt and Goethe used this technique. The different colors and hues arise from various plants ( Waid - Jean Blue, Maidsüß light blue, pennyroyal - green, Atlant - red violet, cinquefoil - deep red, elderberry - magenta) give off different depending on the location, crop type and processing cultural colors.
The technique has been known since the Middle Ages, where it was mainly used in book illumination, for coloring wax and food, and in cosmetics for make-up. The production of handkerchiefs is already described in old color technology books, for example by Theophilus Presbyter at the beginning of the 12th century in his work De diversis artibus or Schedula diversarum artium . Cennino Cennini mentions the technique in his Libro dell'arte o trattato della peintura from 1390, where he called it pezzuole or pezzette (it. = Lobule). The technology is explained in detail in the liber Illuministarum , which was created around 1500 in the Tegernsee Monastery .
Paints of this type are still produced today by specialist companies for artists and restorers using old recipes.
