How do I handle my toughened glass panel?

Toughened glass has all of its Sharpe edges removed though we recommend that when carrying the glass gloves are used. When the glass is being stacked it is best to lean it against a suitable wall ensuring that the edges are protected from hard materials such concrete or metal. The incline of the glass needs only to be slight as not to cause it to slide out at the bottom. If more glass is being stacked in front of the first then you must ensure a suitable material separates each piece. It is important to recognize that the edges and corners of the glass are the most vulnerable.
