What is an egg shell used for?

Eggshells have various uses and practical applications:

1. Fertilizer: Eggshells are a rich source of calcium carbonate, which is essential for plant growth. Crushed eggshells can be added to soil or compost to provide a natural source of calcium and other minerals.

2. Pest Control: Eggshell powder can be sprinkled around plants as a natural deterrent against certain insects and pests. The sharp edges of the eggshells can irritate the soft bodies of insects, discouraging them from feeding on the plants.

3. Seed Starter: Eggshells can be used as eco-friendly seed starters. Fill the empty eggshell with soil, plant the seed, and place it in a sunny spot. Once the seedling outgrows the eggshell, you can transplant it directly into the garden with the eggshell still intact. The eggshell will decompose over time, releasing nutrients into the soil.

4. Drainage Improvement: Crushed eggshells can be mixed into potting soil or garden soil to improve drainage. The porous nature of the eggshells allows excess water to drain more effectively, preventing waterlogged soil.

5. Bird Feed: Crushed eggshells can be added to bird feeders to provide birds with a source of calcium, which is important for strong bones and eggshell formation.

6. Arts and Crafts: Empty eggshells can be used for various art projects, such as painting, crafting ornaments, and making mosaic art.

7. Cleaning Abrasive: The rough texture of eggshells can be used as a gentle abrasive for cleaning delicate surfaces, such as pots and pans, or for removing stains from clothing.

8. Skincare and Cosmetics: Eggshell membrane, the thin film lining the inside of the egg, has been used in some skincare products and cosmetic formulations. It's believed to have moisturizing and anti-aging properties.

9. Teeth Whitener: Some people use eggshell powder as a natural teeth whitener. However, it's essential to use it cautiously as it may be too abrasive for some teeth.

10. Animal Feed: Crushed eggshells can be added to the feed of animals such as chickens, ducks, and other birds to provide a calcium supplement.

Remember to thoroughly clean and dry eggshells before using them for any purpose.
