8 Household Uses for Eggshells


| 8/2/2016 10:19:42 AM


Next time you whip up a quiche or bake a cake, you may want to think twice before tossing the eggshells in the trash. From deterring pests to making better coffee, practical uses for eggshells abound. Note that, except when using them in the garden, raw eggshells should be sterilized before using. To do this, place the shells in a pan on the stove, cover them with water, boil for 5 minutes, and let them completely dry on a cookie sheet.

1. Start seeds

Eggshells make perfect biodegradable containers in which to start seedlings. Tap the small end with a spoon to crack it, then carefully remove the top and empty the egg. Use a funnel or spoon to scoop potting soil into the shells. When the shell is nearly full, use tweezers to gently plant seeds just below the surface of the soil. Place the eggshell planter in a carton in a sunny window, and gently mist the plant daily. When your seedlings are ready to plant outdoors, simply bury the entire eggshell. The shell will break down and provide extra nutrients for your plants.

2. Calcium boost

Perhaps the most obvious way to reuse leftover eggshells is simply including them in your compost. Eggshells are an excellent source of calcium and micronutrients for plants. Crumbling eggshells and adding them directly to the soil is helpful, too. The added calcium can help prevent plant diseases such as blossom end rot in tomatoes.

3. Coffee mate

Brewing coffee with eggshells can reduce its bitterness. After sterilizing, add crushed eggshells to coffee grounds and brew as normal for a cleaner, milder-tasting cup.



4. DIY doodlers

Eggshells can form the basis of homemade sidewalk chalk. Using a mortar and pestle, crush sterilized eggshells into a fine powder. In another bowl, mix 1 teaspoon flour and 1 teaspoon hot water. Add 1 tablespoon of eggshell powder and mix into a thick paste. Use food coloring or natural dyes to color the paste, then shape it into a stick by rolling it up tightly in a paper towel. Let it sit for three days, then the chalk is ready to use!
