To Start Using   Just 1. Flex metal disc back and forth until crystals form. 2. Knead pad to soften.

 How To Prepare The Pad For Re-Use 

1.	Boil water in a pot.
2.	Place a cloth on the bottom of a pot.
3.	Place the pad on the cloth inside the pot and continue to boil water until all crystals are dissolved and the pad is completely clear.
4.	When the pad is completely clear take it out of the water and place it on a cloth to cool down. Completely clear means completely clear - If there is even one crystal, continue to boil until it melts. Hold the pad up against a light and make sure there are no crystals left.
5.	When the pad cools down, it is ready to be used again.
6.	If crystals start forming while the pad is cooling, repeat steps 1, 2 and 3.
