Chalk boards are very visceral, Bringing a chalkboard instead of powerpoint when giving a presentation, makes for a much better presentation, A whiteboard is almost as good but does not have the same impact as a chalkboard.

#33In university I installed a rather large sheet of acrylic on the wall in my dorm room. I then used "liquid chalk" markers to write on it.
Acrylic and the markers were more expensive than other solutions, but they could be erased either dry with some piece of cloth or a little bit of water.
Might be another option for anybody looking into that topic.
edit: That solution was not magnetic, though. I installed a magnetic strip on the side for that.

#35I have to ask. Why is it "white"-board vs. "chalk"-board? Back in elementary school, I learned to call the former "black"-board.
In the UK they still call them "blackboards", I've never seen a green one over here.

Regional variation? When I was growing up (in California, in the 1970s and 80s), we called them chalkboards because, you know, you used chalk to write on them. Also, they were often green. Do you call it 'soda' or 'pop'?

#37Very similar to "chattering", a technique in pottery for adding surface texture. In that the surface marking implement is used in a way that elicits rapid reciprocation leaving a periodic pattern in the clay surface.
Examples, https://youtu.be/FBxhkRu9imA using a long springy tool, https://youtu.be/W_P-L0axcqs using a short tool that pivots.

I've never heard 'chalkboard' before fwiw.

I was born in the 70s, raised in Oregon, and we called them chalkboards. "Blackboard" sounded old-timey to me, like something you'd hear on Little House on the Prairie. A Google search result points out that green became a common color for chalkboards, and in retrospect I think most of mine in school were green.
More googling says that the original blackboards were slate. The green ones were porcelain.
