Step-by-Step Guide to Drying Eggshells in the Microwave
Now that your eggshells are clean and prepared, it’s time to dry them using the microwave. Follow these steps for optimal results:
Step 1: Place Eggshells on a Microwave-Safe Plate
Arrange the cleaned eggshells on the microwave-safe plate. For best results, make sure they are in a single layer to avoid uneven drying. If your shells are cracked, spread them out evenly to ensure they dry properly.
Step 2: Microwave on Low Power
Using your microwave’s low power setting, heat the eggshells for 30 seconds. It’s crucial to use low power to prevent burning. Microwaving on high can cause the eggshells to become too brittle or, worse, ignite.
Step 3: Check for Moisture
After the initial 30 seconds, carefully remove the plate and check the eggshells. They should feel warm, and there should be no signs of moisture. If they still seem damp, return them to the microwave for an additional 15-30 seconds.
Step 4: Flip and Distribute (Optional)
If you notice that some areas are drying faster than others, consider flipping the eggshells or redistributing them on the plate to facilitate even drying.
Step 5: Let Cool
Once the eggshells have dried completely, allow them to cool. Microwaved items can retain heat, and letting them rest prevents accidental burns.
Step 6: Store Properly
After cooling, store your dried eggshells in a clean, dry container. A glass jar with a lid works well to keep them protected from moisture and pests. Label the container for easy recognition.
Uses for Dried Eggshells
As you’ve learned, dried eggshells are incredibly versatile. Here are some creative ways to put yours to good use:
