## Why Eggshells Are Worth Keeping
Eggshells are made primarily of **calcium carbonate**, the same compound used in chalk and limestone. Calcium is not just essential for our bones; it’s incredibly useful in other applications too.
* **Nutritional Value**: Ground eggshells can be used as a calcium supplement for humans or pets.
* **Gardening Aid**: Crushed eggshells can enrich soil, deter pests, and reduce acidity in compost.
* **Cleaning Tool**: The coarse texture of eggshells makes them an eco-friendly scrubbing agent for kitchen containers.
* **Household Deodorizer**: Eggshells can help neutralize unpleasant odors in your fridge or garbage can.
However, using raw eggshells comes with a risk: **bacteria, like Salmonella, can linger on the shell**. That’s where **boiling comes in**—it sterilizes the shells, making them safe and effective for a variety of household uses.

## The Simple Step That Changes Everything: Boiling Eggshells
1. **Kills Harmful Bacteria**: Raw eggshells may carry pathogens, which can be harmful if ingested or handled in the kitchen.
2. **Makes Them Easier to Grind**: Boiling softens the membrane inside the shell, allowing for a smoother, finer grind.
3. **Reduces Odor**: Boiling removes lingering eggy smells, making them more pleasant to handle.
After boiling, allow the eggshells to **dry completely**. You can place them on a baking sheet in a warm oven for 10-15 minutes or let them air dry. Once dried, they can be crushed or ground for multiple household applications.

* **Crush or grind the boiled shells** into a fine powder.
* **Sprinkle directly into soil** or mix into your compost.
* Over time, the shells break down, **releasing calcium and other trace minerals** into the soil.
