I agree, it does seem silly to ship recycled glass all over the country. I wish there were more local sources, or an easy way to make you own.
just did a search on you tube
Speaking of Glass Terrazzo. I am curious about what loading rate people are using for this. Glass:Concrete. Also, whether you're pouring an SCC mix or hand packing a glass rich mixture. I have one coming up and I'd like to get some recipe ideas outside my own head. We have often stuck the glass down to the mold both horizontals and verts, then sprayed or poured over them and stippled the surface around the aggregate. Thanks.
