Cullet Glass

Cullet glass is recycled glass, which is run through a crusher. The resulting product can take the place of pit run gravel used for backfill. We were lucky to be able to obtain cullet glass from our local quarry. We found the product as easy to work with as gravel and it compacted very nicely. Many municipalities are using it for roadbeds and as substrate for recreation fields. In Australia cullet glass is being mixed into concrete to take the place of sand. Contrary to what you might think the edges of the glass are not sharp, you can take a handful of cullet glass and rub it with your hands and not get cut. When the cullet glass first arrived at the job site it wasn’t very attractive. But as soon as the rain hit it and the dirt washed off, the glass became a kaleidoscope of color and light. Cullet glass would make a beautiful walkway or it can be used to edge your garden as Tom St Louis does. He claims slugs won’t crawl over it and the additional heat retention and light refraction helps grow whopper tomatoes.
