Thanks. Let me explain why I want to do it.

When I weld (I am learning to weld and lay a lot of weld beads), I see
very little outside of the arc area, due to darkening lens of the
helmet. Hence, my test welds that I do on plates, wander and are not
straight. So, I want to mark a line that I could follow.

Isn't that what soapstone is for?
