Glue vs. Paste: What's the Difference?

Edited by Aimie Carlson || By Janet White || Published on January 22, 2024
Glue is a strong adhesive substance used for bonding materials, while paste is a thick, soft, moist substance used for sticking, especially in paper crafts.

Key Differences

Glue is typically a more fluid and strong adhesive, used for permanently bonding various materials, whereas paste is thicker, less strong, and often used for paper-based applications.
The chemical composition of glue can vary widely, designed for specific materials like wood, metal, or plastic, while paste is generally made from starch or cellulose, making it more suitable for art and craft projects.
Glue often requires time to set and bond, providing a durable hold, whereas paste offers immediate adhesion but with less long-term durability.
In terms of toxicity and safety, many glues contain chemicals that require caution in handling, while paste, especially those used in schools, is typically non-toxic and safe for children.
Glue is available in various forms like liquid, gel, or sticks, tailored for different applications, while paste is commonly found in tubs or jars and is applied with a brush or fingers in crafts.
