This ageing accelerated by physicochemical - chemical reactions on supports recent, hygroscopic, a base of paper, parchments, fabrics or similar, free or not

摘要

Accelerated aging of new hygroscopic substrates comprises applying a water-based ink comprising decolorized shellac or gum Arabic and a colorless diluent, immersing the substrate in a vinegar bath, and physically distressing the substrate to simulate wear. An Independent claim is also included for a kit for carrying out the above process, comprising a bottle of vinegar-based liquid, several bottles of inks based on shellac or gum Arabic, a bottle of colorless diluent, a bottle of dust patina, a bottle of colorless protective fixative, a pen holder and drawing pens.
