Interesting, I stand correct on the shattering bit. at least as far as regular glass is concerned…
I found a few youtube videos of other companies that offer lasers to do this, and they don’t appear to be using CO2 lasers (the green beam color is probably a giveaway).
That one says they use a vanadate laser, but there is a wikipedia article that says YAG lasers will work as well.
(I am excited to get a glowforge and I do a lot of googleing)
