Chalk, defined by the free dictionary as a soft, white, gray, or yellow limestone consisting mainly of calcium carbonate and formed primarily from the accumulation of fossil microorganisms such as foraminifera and calcareous algae. Chalk is used in making lime, cement, and fertilizers, and as a whitening pigment in ceramics, paints, and cosmetics. The chalk used in classrooms is usually artificial.

The latter part is what this hub is all about – the artificial chalk. The one that is famous in the classroom for writing and drawing on a blackboard that is not really black but green.

Did you know that chalks have other magical uses aside from solving the equations on the board? So, from the classroom to your household, here are my top five uses of chalk:

1. Keep ants away

Stop using that harsh chemicals and spray. Here’s a nifty trick. Draw lines with chalk around your house to keep the ants away. Ants won’t cross a chalk line. Why? They don’t know how to hopscotch. Okay, that's a joke. Kidding aside, ants don’t like the calcium carbonate in the chalk. So, to keep ants out of your house, draw chalk lines around the doorways and windowsills of your house. If they are already in your house, find out where they are coming from and draw a chalk line therein.

2. Remove stains

Ring mark on the collar of your shirts is ugly and even though the shirt is freshly laundered, the mark makes it feel like it’s not completely clean. This ring mark is quite hard to remove even with pre-soaking. How does the chalk help? Rub the stained collar with chalk before washing. The chalk particles will help absorb the oil from the stain making it easier to get rid of the mark.

On an added note, the ring mark on your shirt isn’t really dirt. It’s not because you have dirty neck that leaves this ring mark around. It is a collection of melanin pigment from your shed skin cells, since the collar is the area that rubs off the most of your skin cells.

3. Stop tarnish

Chalks absorbs moisture and help prevents tarnishing. So, for your precious silverware, store it with a chalk wrapped in cheesecloth. You could also do the same with your lovely pieces of silver jewelry.

Ooppss, wrong screwdriver! This is not what I meant. (:- See next photo.

4. Steady a screwdriver

To prevent slipping while you screw, (doesn’t sound right) rub chalk over the handle of the screwdriver. It will create friction and will prevent slipping from your hands.

This is it!

5. Hide cracks

Not that kind of crack (whatever is in your head) but yes, it can cover those hairline cracks on your wall. Chalks are now available in color. So, match the right color until you are ready to paint your wall.

Did you know?

1. Toothpaste also contains small amounts of chalk that serves as a mild abrasive.

2. Chalk can also be taken orally in small doses as antacid.

3. Chalk mix with cinnamon and sugar in gum water was used to treat diarrhea esp. for infants.

4. Chalk is highly porous making it a natural storage tank for water.

5. If you subject chalk to heat and pressure it turns to marble.

      Wow.... I must say I enver knew chalk had so many uses. I usually can't stand the stuff (I'm picky about how it feels and writes just one of my peeves).....anyhoo....

      The cracks in walls is a great trick, the "stay away ant line" is a great trick...used to treat diahreha in infants?! Very interesting...

      Thanks for sharing these chalk tips NEVER in my life would I have guessed....and I tend to be a self proclaimed do-it-yourselfer, naturally kinda girl. Thanks again!

      LOL! Can I have that screwdriver?! Really, this is an awesome chalk talk. I may not be choked by your hub but this is an awesome eye opener to those persons who just throw the chalk whenever they are irritated or angry with someone (lol!).

      Hello alvairs! Thank you for dropping by. I'm glad you enjoyed the twist. I thought the chalk although colorful is quite boring to begin with, so there goes the twist.

      Enjoy your screwdriver (drink)!

      Hello Miswa! Nice to meet you and thank you for reading and for your comments. I know about those pesticides kind of chalks. I've seen them in the Chinese store--quite interesting but just not sure how effective can they be. I'll try them next. (:

      Yes, I want Coffee but no egg in my rice. Coffeegginmyrice, thank you for your feed back. The chalks now a days are more refined, no more powdery particles. White dust long be gone. Happy Friday!

      That was great, i didn't know that chalk was able to do all the things that are referenced. I enjoy the funny twist to your post. Great job.

      Interesting..especially the screwdriver part...LOL!

      FYI: There are commercially prepared chalks that are pesticides. Same trick as with ants but more effective against roaches.

      Cool Chalk Talk, Cris! What a wonderful thing to know what one fragile chalk stick can do and all I know aside from writing, is that it keeps ants away but really, I think I've seen one of my ants crossing the white line, ahahaha! He was definitely trespassing!

      I also remember about not getting the chalk powder on our cheeks (when I was in school), you see, it just wouldn't give us a powdered look, but they said it could cause white itchy spots on our face (ap-ap) in Cebuano. And I don't like the filmy feeling of chalk powder on my fingers, so I always wash my hands after handling a piece of chalk.

      Good hub and interesting!
