Chalk’s Future

Future Directions


I think chalk will be around for a long time, probably used concurrently with other developing technologies in the classroom setting. I don’t imagine however, that anyone will invent a bigger, better chalk. Chalk technology has probably reached its peak. However – chalk and the chalkboard seem to be the analogy of choice when speaking of computer technology in the classroom. This will most likely continue.

Scope of Chalk

I found many things of interest while researching chalk technology. Chalk’s presence in our society is absolutely pervasive. Here are a few things chalk is used for that you may not have thought about –Chalk is used to outline the position of corpses for forensic investigations.

  • Chalk is used in Billiards (chalking the cue), Rock Climbing, Weightlifting and Gymnastics. Chalk will probably be at the Olympics!
  • Chalk is used when you have a flat tire. Once the leak is locates, it is marked with chalk for repair.
  • Chalk is used in the construction industry. Different colors mean different things. Chalk marks are used to indicate where steel should be bent, where pipes should be laid, and where wires should be pulled. Are you familiar with chalk lines? 
  • Chalk is used every day by for sewing, tailoring, and quilting.
  • Chalk is the best hopscotch medium!
  • Chalks are still used in art.
  • Chalk has been combined with insecticides in other countries and smuggled into the United States where it is sold under different names, such as “Pretty Baby”. This insecticide is meant to be drawn across the floor with the idea that bugs will walk through it and die. Unfortunately, there have been reports of this chalk being eaten by children.


How is Chalk Made?

Where does Chalk come from?

The word chalk comes from the Latin word ‘calx’.

Chalk comes from limestone. Most of the chalk you can get today was made almost 50 to 100 million years ago. It is chemically made of calcium carbonate. The porous sedimentary rock naturally deep under the sea where small circular calcite plates called coccoliths accumulate to form limestone.

In its natural form chalk can be found in colors ranging from white, grey, and yellow. The different colors occur due to various impurities in the chalk.  Did you know that if you subject chalk to heat and pressure it can turn into marble.


Where do you find chalk?

England has a lot of natural chalk deposits. Their cliffs are made from chalk, and can resist the weather much better than normal cliffs. Since chalk is a very porous material, it tends to absorb water and store it. You may find pictures of tall and steep cliffs like the Isle of Wight as great examples.

Use of chalk

Chalk is mostly pressed into white sticks which are then used for a variety of purposes from scribbling on the blackboard, outlining designs on fabrics for tailors and making art works on sidewalks. Some of the different uses of chalk and their types include blackboard chalk which is made from gypsum, sidewalk chalk, agriculture chalk made from calcium carbonate and calcium oxide.

Chalk also has a variety of other uses, it was originally used to draw those white lines that define the court boundaries in sports like tennis, badminton and other such sports. It is used in agriculture to treat soils that are too acidic in nature. You can use it if you are a gymnast or rock climber to remove the perspiration in your hand. Did you know even your toothpaste has a small amount of chalk in it.

Chalk on a board … a longboard that is

As I described earlier I have a passion for chalk and boards. And I found an other great example which combines the two.

The Madrid longboards – Strokes Rocker Pintail Longboard, which is elegant and could be just a chalkboard as any other. The strokes do remind me on the way the chalk leaves a trail behind on the chalkboard, so definitely a plus in my book.




What do you think, is this the one?



Where does it come from and how is a chalkboard made?

The chalkboard is a flat, vertical writing surface on which anything can be inscribed by means of a piece of chalk. The device is generally used for educational purposes, but it can also be found in the workplace, the home, and restaurants. While chalkboards can be manufactured from a variety of materials, porcelain enamel is the most common material used in today’s chalkboard.

The origins of the chalkboard date back to the early decades of the 19th century. The forerunner of the chalkboard was the small, paddle-shaped hornbook. This item had been in use in schools of medieval England, and by the time of the Revolutionary War era in colonial America, it was carried by legions of students.

The hornbook was a strip of wood with a piece of paper fastened onto it. On the paper were a variety of learning aids in small print. A typical hornbook would carry both the Lord’s Prayer and the alphabet, and a translucent sheet of animal horn covered the paper. The hornbooks were small objects, sometimes with a hole at the bottom so they could be tied on a string and worn about the neck.

all very fascinating and educational.

Awesome ways to have Chalkboards in the House

Did you know there are people who want to have a chalkboard around them all the time?

Some folks can’t stop doodling…

the whole day.

In the office, on the road and even at home. The great thing is you can just paint you have with chalkboard wall paint. And have a huge empty space to get your juices going.


Some architect and interior designers have full rooms , intended to invite scrawls, notes and artwork from guests on blackboard kitchen and living room walls. Feeling adventurous and you too can add chalkboard coating to doors, tables and other furniture as well – in dark slate gray/black or classic ‘schoolroom green’ as desire

At the beginning of the day you have a blank black-slate surface and end of the day its one bit in creative chaos – greats for homes with kids, or ones with evil genius scientists perhaps.


Here a fun one for the kitchen is spotted and combines my love for skating. Great work longboards USA.



Note: an eraser will never quite clear all the dust the way a wet cloth cleans up a dry-erase white board, so plan on living with the aftermath of this architectural choice.

Till the next one,
