opinion

what is your opinion on finely grinded green glass bottles and finely grinded white stone used as a building material
and what would you see it suitable for?

 

I'd be worried about dust from the glass, but maybe you don't mean quite as fine as that? Do you mean building in the garden?

 

Would it be any good to put around plants to keep slugs and snails off?

Glassworks waste was used as an aggregate in the last town I lived in, it made the Lime Mortar set really hard.

 

I have seen it

I can answer that one...I don`t think so.

 

I'd see it suitable as a walkway of some sort where it doesn't matter if a stray piece or two comes loose. It sounds like you are going for a mosaic effect, no?

 

I personally wouldn't bother putting it around plants as a slug/snail deterrent, it's just going to disappear into the ground.

If someone offered me a few barrow loads, (and I was perhaps building a new patio using paving slabs), I think I might use it as an alternative to the occasional slab - interspersing the slabs with say a square of the ground glass to create some sort of pattern, but I don't think I'd use either product, without tamping it firmly into a bed of cement.

 

I have seen it used somewhere on a wall and it felt extremely smooth and then I looked closer and, to my amazement, there were minute pieces of green glass and white stones.
