(Tempered Glass) - This involves heating and then cooling glass after it has been cut to the correct size. This allows it to stretch more then annealed glass so is perfect for large panes. However this glass will shatter into 1000’s of pieces if struck with a sharp object, not very secure.
This is like the glass used in car windscreens it is a 0.4mm laminate sandwiched between 2 sheets or 3mm glass. This stops the glass separating when broken and is more secure then toughed, but it is twice the price.
