Sonically I think any type of glass is a bad idea. Glass creates all type of problems that Im not going to discuss while answering this question. One of the very best shelving materials one can use IMHO is ACRYLIC!

The marketing info from Billy Bags has absolutely no information on what "Cracked Glass" is.
If it's similar to laminated or security glass it might possibly have some merit as a shelf material but still wouldn't be my first choice; beyond that, if it is basically a simple glass product I wouldn't have much use for it. Dogmatic or not, I have not heard a "simple" glass product that sounds even remotely decent as a shelf material.
I've experimented with granite, marble, glass (basic and laminated in various thicknesses), cutting boards, phenolic (which is pretty similar to the Black Diamond shelfs in performance at a fraction of the price) and acrylic and I agree with Lak that acrylic makes a very good shelf material.
Acrylic can, however, start to get a bit pricey, particularly if you need it to support a bit of weight.
An extremely cost effective way to create a great shelf is to put together a constrained layer using a thinner sheet of extruded acrylic on top, a piece of baltic birch (which is dirt cheap) underneath it, with a piece of thin (1/8" or so) neoprene sheet between the two. The neoprene sheet should be available online or from an upholsterer.
This is what I'm using under my table now with an older style Target wall mount and it is, by far, the best and most natural sounding shelf material I've ever used.
I'm using 1 1/4" phenolic in the rest of my floor mounted rack as shelf material (under integrated, phono preamp, etc) but I'd guess that the above would outperform it for a fraction of the price-it definitely did under my turntable.
I've seen turn table bases made out of wood and acrylic, but never out of glass.
Just curious....have you actually tried it or just making assumptions based on what you believe to be true about the characteristics of glass?

Herman, I've tried glass, granite, a number of other stone, various woods and I prefer the sound of acrylic 1/2" to 1" thick depending upon what sits on top of it. If others prefer the effects of glass I think that's wonderful.
When I said turn table bass I might have used the incorrect term, I was referring to what a turntable platter, tone arm etc is attached to. I know there is a correct name for it but it doesn't come to me at the present time.
