History of Glue

Glue has been around for thousands of years in one form or another – historians have found evidence that glue was used as far back as 8000 BC. Resin was often used as an early form of glue and was useful for attaching spear heads and securing other hunting aids and commonly used tools. Resin from birch trees was particularly useful and was widely utilised.

Types of Glue

There are countless types of glue, each serving a unique purpose and used to stick different types of material. Here are some of the more commons types of glue.

Craft glue – This is usually made from PVA and is widely available in craft shops and toy shops. It’s great for sticking paper, card and other lightweight materials, such as embellishments and scraps of fabric. It’s ideal for craft projects, school projects and general lightweight adhesion. It is not generally suited to more heavy-duty tasks, and it does break down over time.
