At the click of a button, the heat pads will reach 54°C (130°F). The pads are safe and non toxic due to the innovative use of the salt based solution, Sodium Acetate.
On flexing the small metal disc inside the pad a molecular reaction is started causing the solution to crystallize. Starting this chain reaction causes the entire solution to solidify. During the reaction (from liquid to crystal form) energy is released in the form of heat.
Gradually the heat pad will start to cool down, returning to its original, solid state. The time this takes is dependable on the size and model of the heat pad, however the process can be initiated and the pad re-used again and again.
After Finishing simply...
Boil water in a pot
Place a cloth on the bottom of the pot
Place the pad on the cloth inside the pot, and continue to boil the water until all the crystals are dissolved, and the pad is completely clear
When the pad is completely clear take it out of the water and place it on a cloth to cool down.
When the pad cools down, it is ready to be used again
