Opinions on Glass Shelves

I am thinking about buying a new audio rack. When I tap on the shelf below the shelf on which my turntable sits while the needle is on an LP at rest, I can hear the a slight echo in my speakers.

I’ve looked into various audio racks including some from Billy Bags. The salesperson at Billy Bags told me that their ¾” cracked glass was sound-deadening and would provide excellent sound isolation. To me this is counterintuitive.

Has anyone had any experience with cracked glass from Billy Bags?

Has anyone had any experience with glass shelves in general?

Take a look at slate. I believe it to be the ultimate constrained layer material. Sound travels though it slowly, and is actually changed along the way. The downside is its weight, but the payoff is excellent.

Glass reflects sound, and sound travels through granite faster than through water, so I wouldn't choose either of them. They do look nice, and may not actually be detremental.

Then, there is concrete and wood. Depending on the composition, one of them may be decent. Of course, there are the foam composite shelves that are engineered for the task, too.
