Can I cut glass with a MK diamond saw tile cutter?

I have some 100 year old whisky bottle necks that I want to cut off nicely
and make hat pegs out of. I figured I would saw them at a slight angle so
that when mounted on a flat piece of barn wood, they would point slightly
up.

Has anyone ever cut something like this? I would make a small cradle to
hold them and get repeatable cuts, and would use a very slow feed with the
water spray.
