Can we make a hole on tempered glass or engraving ?

IT CAN BE DONE ONLY WITH HIGH COST

ITS BETTER TO REORDER THE GLASS THATN RECUT THE TEMPERED GLASS

CUTTING CAN BE DONE FOR TEMPERED GLASS AS FOLLOWS:-

Step 1 - Clean the Tempered Glass Thoroughly

Make sure there is no dust or dirt particles that could get in the way of a clean cut. Clean it thoroughly with window washing solution and allow it to dry completely.

Step 2 - Anneal the Glass

Heat the glass in a craft oven until it reaches 900 degrees Fahrenheit, then turn off the oven and allow the glass and oven to cool for eight hours.

This annealing or heating process will alter the glass so that it is no longer tempered and will not shatter when cut.

Step 3 - Prepare the Glass for Cutting

After the glass has been annealed, place it on a flat surface and place a t-square over the place you wish to cut it.
