All of our glass is tumbled to remove sharp edges. Our glass pebbles have a smooth polished finish. All of our glass is recycled post-consumer and post-industrial glass bottle and scraps. Some of the glass is simply ground and tumbled with various flaws and inconsistencies common with recycled glass. Most of our glass is re-melted and re-colored to ensure a mostly consistent colored and sized end product. But as with all recycled glass variations between batches can occur.
