Does anyone know if Eastman Tritan engraves well? It says bpa-free and impact resistant and I found that it is a copolyester by googling. I have someone who asked if I could engrave on glasses made of this material. I can get one from Walmart and try it but some of you may already know.

Have not engraved any, but on Eastman's site it states it has a "high resistance to thermal shock" and isn't that essentially what you do when you engrave it. Be interesting to see. Let us know the results of your test if you do it.

It blew a lot of white residue during engraving, but turned out pretty well. Here's the result. I ran it at 100% speed 18% power on a Chinese 60w laser.
