First post (after years of stalking the forum updates)!
Tested this when I first got my GF. I had picked up a few old marble tile samples a while ago and have been using them as coasters so I thought I’d test out a deco and logo engrave design.
Apologies if these don’t show up; I’m new to posting!
We just had an office debate between art directors and interior designers in my office trying to figure it out. Most agree that it’s polished marble, but maybe with a sealant, but not necessarily. Either way, it engraves easily and beautifully!
