I don’t have a uv machine, and likely won’t, but from what I understand.
NTM uses TiO2 (Titanium Oxide) that creates a molecular bond to the glass or metal. Everything else washes off. There are also other types of coatings mostly designed for co2 machines, but can work in a wider range of machines.
If you note that @Bulldog has done porcelain tiles by NTM method and deep engraving. The deep engraving would likely be your result.
The UV is a bit different. The fiber can’t vaporize or ablate the glass but a UV apparently does. I’ve seen 5V uv lasers cut through glass. This is not possible with the co2, not to mention my fiber seems to pass though glass with no issues.
You should be able to engrave, but they will likely have little contrast to see what you’ve lased without some extra work or depth.
Good luck … hope it helps.
