I discussed whether carving/etching tempered glass is possible in a past post. Since Omar sandblasted this lightly for a longer time than usual rather than using a higher pressure setting for a short period of time, it turned out a success! Also note, as I mentioned in my blog post tip that using a very small piece of tempered glass has less forces and was less likely to break.
He provided information on the glass type and thickness, how it was etched and how he installed the led light:
It was a piece of glass from Lowes Home Improvement — 1/4 thickness. I sand basted the piece with 150 grit aluminum oxide with a small sand blaster. The glass was tempered glass. I was very careful blasting at 25 psi for very long periods of time. This piece took 5 hours of work on a Saturday. I learned from this to not to use tempered glass ever!!!! It was a multi stage process. The lights was rgb leds with a remote-control. The frame was custom made from crown moldings and stain wood built in a shadow box frame to fit the rgb transformers and two 9 volt batteries
I want to thank Omar for sharing this and encourage other to leave him a comment below whether you what to thank him for testing multi-stage techniques on tempered glass or ask a question.
