Never ever "glue" your broken pieces together. It will skyrocket the price of restoration, especially if you use rubber, silicone, or epoxy cement. Relax! It is almost certain that it can be repaired!
Pick up all the pieces carefully so as not to cut yourself and not to cause further damage to the broken pieces. Afterward, wrap the larger pieces in bubble wrap or tissue, and put them in a zip lock bag. Don’t forget to put the small and tiny pieces in a tissue paper before putting them inside.
