The main ingredient in eggshells is calcium carbonate (the same brittle white stuff that chalk, limestone, cave stalactites, sea shells, coral, and pearls are made of). The shell itself is about 95% CaCO3 (which is also the main ingredient in sea shells). The remaining 5%includes calcium phosphate and magnesium carbonate and soluble and insoluble proteins(source:http://wiki.answers.com/Q/What_are_egg_shells_made_out_of)
Egg shells are common kitchen waste materials we usually throw in our garbage.It's about time that we learn how to recycle this thing in order to minimize our everyday wastes. We should know that egg shells can be useful in so many ways.
After watching my favorite informative show in QTV channel 11 which is Good news with Vicky Morales, I learned that there are so many uses of egg shells. It actually can help us in our everyday house hold chores, except for that fact that egg shell is a very useful material in school arts.I've learned some procedures on how to recycle egg shells into a useful product. I will enumerate some of the things as I remember from watching the show.
Uses of Egg Shells:
- Egg shell as sink strainer- we all have sink strainers but despite of having one, we couldn't prevent our sink it from clogging due to some waste residue from our dishes. We can make egg shells as strainer when broke into smaller pieces. All sticky residue will then mix to the shells, it will also serve as a dirt magnet when passed thru the sink's tube. Egg shell won't clog the sink passage for it dissolves in time.
- Egg shell as bitter taste remover- try it with strong coffee mix as example. When fine pieces of egg shell are mixed with the coffee, the bitter taste will be removed.
- Vinegar Enhancer- simply add fine egg shells to the vinegar and leave for 2-3 weeks or until the shell dissolves. The minerals that egg shell has will mix to the vinegar so you would have a healthy vinegar.
- Egg shell as art material-Paste fine shells to a drawing and enhance it with water color. You can also design a bottle or a jar by pasting fine pieces to it and paint it with different colors.
The above procedures are best help for us to know what's the best egg shell garbage disposal.
