Product Description:
The Heat Factory is an exothermic warmer, a lightweight pack that generates its own heat when exposed to air. It works by simple oxidation of iron powder, carbon, salt, water, and vermiculite; no fluids, flames, fumes, or odors. The reaction can be stopped at any time by cutting off the oxygen in an airtight container, then restarted within one week. Not otherwise reusable.
