Chalkboard goes clear back, nearly, to the first organized school classroom. For sure, many 100’s of years back. Before that, they used a charcoal stick and drew using whatever smooth surface usable. The difficulty was, charcoal isn’t erasable, so a clean writing surface was required quite often. Before they needed chalk boards, somebody had to invent chalk for the chalk boards. It was learned ground up limestone produced a white powder that could be compressed into a soft white stick that would produce a white line as compared to the black that a burnt stick left. The really good part was that it wiped off of a smooth stone face. Then some bright man shaved thin slabs of slate rock, polished it and the chalkboard was invented. Chalk drawing on stone chalkboards was the medium of choice in the schoolroom for a long time, and eventually the business world realized they could promote on chalkboards, on a regular basis changing their promotional message. There came a day, the old slate blackboards went the way of the dinosaur, making room for new innovations, for example whiteboards using colorful dry erase markers. Currently, if you can find a slate chalkboard discarded by a school, you have a very desirable keep sake. The chalkboard has made a real comeback in recent years because of their nostalgic look that gives a warm and cozy feeling. food market stores, java shops and restaurants, in particular, seem to like the chalkboards, cracker barrel type motif, the chalk isn’t compacted limestone and chalkboards are almost never slate. The majority of today’s chalkboards are either a melamine laminate or textured acrylic because they are light weight and durable. The chalk is now a liquid chalk in a marker pen, so the chalk and the chalkboards have survived, but like everything else, they have been modernized for efficiency.
