![]() ![]() They were similarly used on the Terracotta Army figures. Animal glues were employed as binders in paint media during the Tang Dynasty. Ībout 906–618 BC, fish, ox horns and stag horns were used to produce adhesives and binders for pigments in China. Broken pottery might also be repaired with the use of animal glues, filling the cracks to hide imperfections. Animal glue, known as taurokolla ( ταυρόκολλα) in Greek and gluten taurinum in Latin, were made from the skins of bulls in antiquity. Īncient Greeks and Romans later used animal and fish glue to develop veneering and marquetry, the bonding of thin sections or layers of wood. Egyptian records tell that animal glue would be made by melting it over a fire and then applied with a brush. Evidence is in the form of stone carvings depicting glue preparation and use, primarily used for the pharaoh's tomb furniture. Between 15 BC, it was used for wood furnishings and mural paintings, found even on the caskets of Egyptian Pharaohs. The first known written procedures of making animal glue were written about 2000 BC. Glue deriving from horse tooth can be dated back nearly 6000 years, but no written records from these times can prove that they were fully or extensively used. History Early uses Īnimal glue has existed since ancient times, although its usage was not widespread. However, other animals are also used, including cattle, rabbits and fish. Stereotypically, the animal in question is a horse, and horses that are put down are often said to have been "sent to the glue factory". ![]() Conventionally, keratin glues, while made from animal parts like horns and hooves, are not considered animal glues as they are not collagen glues. These proteins form a molecular bond with the glued object. The word collagen itself derives from Greek κόλλα ( kolla), meaning 'glue'. These protein colloid glues are formed through hydrolysis of the collagen from skins, bones, tendons, and other tissues, similar to gelatin. In addition to being used as an adhesive it is used for coating and sizing, in decorative composition ornaments, and as a clarifying agent. Animal glue in granulesĪnimal glue is an adhesive that is created by prolonged boiling of animal connective tissue in a process called rendering. Not to be confused with keratin glues such as hoof glue and horn glue, which are made from keratin, not collagen. ![]()
