To Activate:
1. Snap the metal disc back and forth and watch the pad begin to crystalize, producing heat.
To recharge:
1. Boil water in a pot.
2. Place the pad on a cloth inside the pot and wait approximately five minutes or until all the crystals are dissolved, and the pad is completely clear.
3. When the pad is completely clear take it out of the water and place
it on a cloth to cool down. If there is even one tiny little crystal, continue
to boil until it melts.
4. When the pad cools down, it is ready to be used again.
What is in the pad?
The pad contains water and food grade sodium acetate (a form of salt)
and a stainless steel disc.
How is the heat produced?
Flexing the metal disc in the liquid creates a chain reaction causing
the pad to crystallize. This crystallization ALWAYS occurs at a temperature of
130 degrees F / 54 C. Once activated, the pad has available to it a
predetermined amount of energy. It will use this energy to increase the
temperature of the pad to 130 degrees F / 54 C and use whatever is left to
maintain that temperature. This ability to produce heat for a period of time
is accomplished because all of the liquid does not crystallize immediately.
Molecules that were not required to heat the pad to its maximum temperature
will remain liquid, and crystallize as required, to maintain the maximum
temperature.
How do you re-use the pad?
Once the pad has given off all of its heat it will remain in its
crystallized state until it is recharged. This is accomplished by placing the
crystallized pad in boiling water for 5 to 10 minutes (depending upon the size
of the pad) until all of the crystals are melted. Once completely liquefied,
remove the pad from the water and store it until you wish to use it again. The pad
should remain liquid as it cools. If crystals form as the pad cools it has not
been boiled long enough. Place the pad in boiling water again until all the
crystals have dissolved and the pad is completely clear.
How long does the heat last?
Smaller pads will be very hot for the first 30 minutes and then will
gradually cool down, while larger pads will be hot for the first hour and then start to cool down.
How many times can the pad be used?
There is no limit as to the number of times a pad can be used.
