Glue, created by Neanderthals 200,000 years ago, was used to connect spear stone flakes to wood using birch bark tar.
Earlier times, natural resources such as plant gums, animal skins, and blood were used to make glue, but these glues were weak and short-lived.
During the Middle Ages, animal materials like hide, hooves, and horns were utilized to construct durable artifacts like books and furniture.
In the 19th century, synthetic glues arose because they were stronger, more durable, cheaper, and easier to manufacture than natural glues.
Today, synthetic glues are popular and have a wide range of applications, including construction, industry, and medical.
