Lets talk about chalk

Most people doing math at university won’t be strangers to writing on blackboards with chalk. However, the experience can vary a great deal. It can range from feeling like scratching a sharp rock on a rough surface, accompanied by screeching sound. And writing is often just barely legible. Needless to say, this can be rather uncomfortable for anyone. But for some people on the autism spectrum, it can be unbearable.

But does choosing a different type of chalk matter? Can one tell a difference? The answer is yes, one can. There is a reason Hagoromo has been called the “Rolls Royce of chalk” (aside form its price tag). From personal experience, I can say it is an absolute pleasure to write with. By comparison to… “lesser” chalk, writing with Hagoromo is silky smooth. Lines are bright and writing is effortless. A worthwhile investment for anyone who regularly writes on blackboards.
