What is Glue?

Glue works by creating a strong bond between two surfaces. When you apply glue, it fills tiny gaps and then hardens. This hardening process makes the surfaces stick firmly together. The strength of the bond depends on the type of glue and the materials being joined.

A Look at Glue's History

People have used glue for thousands of years. The very first glues might have been natural sticky liquids. These liquids would ooze out of trees when they were cut. Ancient people also learned to make glue from animal parts. They would boil animal feet, bones, or cartilage.

Some very strong glues were first made from fish bones. Other early glues came from natural rubber or even milk. These early glues helped people create tools and build structures. For example, Ötzi the Iceman's axe, from over 5,000 years ago, used a natural sticky substance called pitch to hold the stone blade to the wooden handle.

Different Kinds of Glue

There are many types of glue available today. Each kind is designed for different uses.

Natural Glues

Some glues are still made from natural ingredients.

You can make a simple glue at home. Just mix wheat flour and water. This homemade glue works well for sticking pieces of paper together.
Glue can also be made from rice or rice flour. These are often used in traditional crafts.
Beeswax is another natural sticky material. It has been used as an adhesive for a long time.

Man-Made Glues

Many modern glues are made from chemicals. These glues are often very strong and durable.

Liquid Adhesives: These are common glues found in bottles or tubes. They are used for crafts, repairs, and many other tasks.
Hot Glue: A hot glue gun melts solid glue sticks. The melted glue comes out hot and then cools quickly. This makes it harden fast, which is great for quick projects.
Caulk: Some glues are used to seal gaps. They keep water or air from getting into boats or buildings. This type of glue is often called caulk.

Everyday Uses of Glue

Glue is used in countless ways every day.

Art and Crafts: Many kinds of art can be made using glue. A collage is a work of art. It is made by sticking different colored things onto paper.
Building and Manufacturing: Glues are essential in construction. They help put together parts of furniture or floors. Some wood-like materials are made by gluing small pieces of wood together.
Repairs: Glue is perfect for fixing broken items. It can mend toys, dishes, or even shoes.

Staying Safe with Glue

While many glues are safe to use, some kinds contain strong-smelling chemicals. It is very important to use these glues carefully.

Always use glue in a place with good airflow. This means a well-ventilated area.
Avoid breathing in the vapors from strong glues. These chemicals can be harmful if inhaled.
Always read the instructions on the glue's packaging. Follow all safety warnings.
If you get glue on your skin or in your eyes, wash it off right away. Ask an adult for help if needed.

Using glue safely helps you enjoy your projects without any risks.
