A Heat Factory warmer is a lightweight pouch which, when exposed to the air, begins to activate and generate its own heat. The Heat Factory warmer contains a mixture of iron powder, charcoal, salt, sawdust and vermiculite that reacts with air causing an oxidation process that generates heat.
If the heating time is not spent in one use, placing the warmer in an airtight container may temporarily save Heat Factory warmers. For example: A 12-hour warmer can be used for 6 hours one day, stored in an airtight container, then used for approximately another 6 hours another day within a week.
