I had tempered glass cut for my hexagon end tables at a custom glass place (look for a place that does custom windows and doors) It was quite expensive but they have lasted at least 20 years with minimal scratches.
I had custom cut 1/4 inch plexiglass cut to go over my white tile counter top in the kitchen. It does scratch but allows me to roll out pie dough on it without the grout getting dirty. It finally got a crack this year from the heat of a crock pot but it is about 10 years old.
