Can you sterilize eggshells in a toaster oven?

Here's why:

* Fire hazard: Eggshells are flammable and can easily catch fire in a toaster oven's high heat.

* Uneven heating: Toaster ovens often have uneven heating, making it difficult to ensure that the eggshells are sterilized throughout.

* Potential for damage: The heat can crack or break the eggshells, making them unusable.

* Contamination: The toaster oven may not be clean enough to ensure that the eggshells are sterilized properly.

Safe and Effective Alternatives for Sterilizing Eggshells:

* Boiling: Boil the eggshells in water for 10 minutes.

* Baking: Bake the eggshells in a preheated oven at 250°F (120°C) for 30 minutes.

* Oven sterilization: Place the eggshells in a baking dish and bake them in a preheated oven at 350°F (175°C) for 30 minutes.

Important Note: Ensure that the eggshells are completely dry before using them for any purpose.
