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?

didn't look at video, but:

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