> there is one really, really cool thing you can do on chalkboards that you can’t on whiteboards: make dotted lines Seriously?
Then I’ve watched this from a sibling comment: https://www.youtube.com/watch?v=l789l6np-qA
Yeah you can’t do dotted lines on a whiteboard.
He links to the whiteboard post, which is interesting because it shows the toothpaste technique for cleaning them. The best buy ever for me was this large, glass whiteboard which is so much easier to erase and clean than a normal whiteboard: https://www.glasswhiteboard.com/
Porcelain whiteboards are nice, I've always managed to get them very clean with just rubbing alcohol.
Is there any concern about chipping or even breaking with the glass whiteboards (if, for example, it somehow falls on the floor, eg during moving)?

>Is this just because my grade school used cheap low-grade chalk? Most likely yeah. I remember reading here about the fairytale that is Japanese chalk and that US professors were hoarding it. I assume it must feel orgasmic. We didn't have that kind of opulence in Eastern Europe. Chalk and blackboards here sucked ass, including the cleanup process students were responsible for. Schools switched to whiteboards and mark…
Hagoromo does feel pretty nice to write with. It’s thicker and it writes smoother than standard chalk. It also has some sort of coating on the sides so it doesn’t get everywhere. It doesn’t break easily when dropped. It’s good but not hilariously better than decent chalk. I find that because of the coating you have to pick a side that you’re going to write with, and this small amount of mental energy is a small roadb…
I still find blackboard + chalk to be a heinous combination. Is this just because my grade school used cheap low-grade chalk? I do have a weird physiological reaction to 'fffffffff' friction sounds. A hard cheap pencil against cheap paper, making a similar raspy sound as chalk-on-blackboard, with cause me to reflexively (and uncontrollably) suck my lips in tight, as if protecting my teeth from the vibrations. Back in…
Definitely yes. Good chalk and good boards sound completely different.

Straying a bit from the topic, but those 'magic eraser' home cleaning products work on laminated plastic, like you find on day-planner erasable calendars.

I have to ask. Why is it "white"-board vs. "chalk"-board? Back in elementary school, I learned to call the former "black"-board.

I think I watched a video on it a long time ago and seem to recall that professors immediately break the chalk in half before using it. I don’t remember why.

The things here is that there's a technique to make the chalk "skip" on its own, by finding some kind of friction equilibrium/magic point while doing a normal stroke so you don't need to manually control the point of the chalk to form each dot.
Really really cool.
