The glass is broken without the tumbling processes that other manufacturers use to remove the sharp edges where they scratch and scuff the glass. Our processes make our glass the most brilliant glass in the industry. It is then filtered and cleaned to remove any small debris during the manufacturing process. Our glass is not tumbled in any way, and this is why it is so brilliant and not scratched. It can have sharp edges since it is not tumbled, so be careful, we don't recommend handling the glass without protection like gloves.
