In the following MIT video, some kind of thick chalk (not sidewalk, already tried it) is used in the lecture:

It looks like great chalk. Or what chalk is this easy to write with?

coffee shops use this kind of chalk a lot because it allows them more control when drawing pretty menus on blackboards.

Thanks for the suggestion. I have to erase a board probably 10 times a lecture, so wiping it down with water will not work well for me.
