Recycled Glass Tiles

Glass has a lot of great qualities. It's made primarily of sand. There aren't issues of chemical off-gassing (at least not after it's cooled). It's recyclable.

Shouldn't we use it more frequently for a building material?

We lose a lot of energy from our houses through the window panes, so glass probably isn't the best choice for exterior walls, but consider the beautiful and durable floor tiles made of recycled glass that are available. What about a counter top made of glass? Do you have another use for recycled glass? Share your ideas below.
