Toughened glass

I am wondering if panels have a chip in an edge or corner, at what size do they present a risk of breakage? From what I have read,the compression and tension layers increase as glass thickness increases. If a panel shows damage and it did not break, I read the chip did not penetrate the tension zone. Is it therefore unlikely to break? What is the expected damage size measured along the edge and face in say a panel of 6mm compared to 19mm of a chip that is likely to fail?

Thank you.

Trends in Glass Architecture

Green design, or the use of energy efficient and environmentally friendly products in design, has become a huge trend in the architectural community, and liberal use of glass is one of the signatures of this trend. Allowing natural daylight into the space using high performance glass cuts consumption of electricity and adds a cheery element to interior space.

Exploding laminate glass

We had new cooker hood fitted three years ago. It has, had, a laminate glass top. Two weeks ago my wife went into the kitchen in the morning to find it covered in tiny pieces of glass. The glass top had exploded during the night. Can the glass be tested to detect contamination by stray metal atoms? Should I risk having a new piece of glass put in?
Any advice please?
