## Why It Works
Egg white proteins form strong adhesive bonds as they dry and denature. The protein film is particularly effective on porous materials like paper and cardboard because the proteins wick into the fibers and anchor mechanically as they set. The salt in the recipe slightly alters the protein structure, producing a thinner, more spreadable consistency and acting as a minor preservative. Dried egg white glue is transparent, flexible enough not to crack on bent paper, and archivally stable (it's been used in bookbinding and art restoration for centuries).
## How to Do It
1. Separate one egg and place the white in a small clean bowl.
2. Add a small pinch of salt (about 1/8 teaspoon).
3. Beat with a fork until slightly frothy and uniform. You're not whipping it to peaks — just combining.
4. Apply with a brush to the surface you want to adhere. Work in thin coats.
5. Press the pieces together immediately and hold for 30 to 60 seconds.
6. Let dry completely — at least 30 minutes for a light bond, several hours for full strength.
7. Store unused glue covered in the fridge and use within 24 hours.
## Pro Tips
- This glue works best on paper, thin cardboard, fabric, and lightweight craft materials. It's not strong enough for heavy cardboard, wood, or structural bonds.
- For decoupage: apply a thin layer to the surface, lay your paper piece, then apply another coat over the top. Let dry between coats.
- If you need a slightly thicker consistency, reduce the egg white over very low heat until it begins to thicken, then cool and use.
## When to Use This
Paper crafts, collage, decoupage, temporary fabric adhesion, and any situation where you need a quick, non-toxic adhesive and don't have craft glue on hand.
