Blackboard chalk uses
For centuries, chalk has been used to write on blackboards. But thanks to its water-soluble properties, chalk has a whole range of uses:Pavement art: Children love to draw on the pavement with colourful chalk. Who hasn’t seen the hopscotch games, the multicoloured flowers and rainbows or the colourful stick figures? But it is not just children who have discovered the blackboard chalk. Even seasoned artists use chalk to create beautiful paintings on streets and pavements.
Schools: You probably remember your days in school, when the teacher wrote equations and grammar rules on the blackboard that you either had to solve or copy down onto paper. Often streaks of chalk remained when the board was wiped clean. Even today, chalk blackboards can be found in every classroom.
Restaurants and cafés: At the entrances to cafés or restaurants, you will often find chalkboards that show the current offerings in artful lettering. At the till, attention is drawn to the day’s special on a small blackboard. Have you found yourself marvelling at the impeccable, ornate writing and detailed depictions of cups and pieces of cake?
Why chalk screeches on a blackboard
Are you among those who wince when the chalk screeches on the blackboard? Many people find the sound unpleasant. The principle is the same as with string instruments or squealing brakes and is called the stick-slip effect. Simply put: The friction between the two surfaces, i.e. between the blackboard and the chalk, creates a vibration, the frequency of which is perceived as a screeching sound. The shorter the piece of chalk, the less it screeches. That is probably one of the reasons for those very small pieces of chalk underneath school blackboards.
