OX HIDE Generally considered the finest and strongest of organic glues. This material from rendered down hides of old oxen or cattle, provides the darkest, most durable and possesses the greatest strength. Water soluble, it by itself is not waterproof. Other natural materials can be added to many of the hide glues to make them waterproof. The materials (strongest wood glue) have a shear strength slightly less than that of modern epoxies.


HORSE HIDE Made of horse hides usually provided by slaughter houses. An excellent quality glue, however if younger hides are used the glue will not be as strong as if made from older animals. Does not possess the strength and toughness of ox hide glue. Hooves are sometimes added to hide glue mixtures, although hooves make good glue they are not as strong as straight hide glue.
