"Inspired by your work I had recently read a bit about laser engraving and laser cutting. Sadly the two materials (beside wood) that I would really like to work with are also the extremely tricky to work with. Glass, because it is too transparent and metal because it is too reflective to be an easy job for lasers."

Metal is as you already guessed also no go. It is not only pretty resident but it would even damage the laser tube of a CO2 laser (I use this type of laser) because it can not handle reflections.





"A main problem when engraving glass is the dust it produces. I don't have a room in which I could get savely rid of the potentially harmful (if inhaled or if it gets into the eyes) dust."



This and the possibility that the glass breaks due to thermal shock are the reasons it is forbidden. The

"However recently I got some good material to work with (new years celebrations can provide you with some materials (empty bottles) abandoned on the street by the owners

)"



transparent is of course hard to overcome but it is possible to engrave it if you have enough power. There is also a small trick which also improv the engravings. Have a thin wet piece of paper (for example newspaper) above the glass.How do you do your engravings by the way? Do you use a small drill?They probably never imagen the true fate of there bottles.
