Toughened glassware is far less likely to break under impact and will not produce sharp shards and edges when it is broken. The glass is designed to shatter into small fragments, think about a car windshield, which are comparatively safe to handle and unlikely to cause damage or injury. Organic ink is used to decorate our toughened range, its available in 1 - 4 colour prints. The print is dishwasher resistant to around 500 cycles, factors can effect this, but not fully scratch resistant. Best of all we dont charge any extra for toughened glass!
