What Is A Heat Factory Warmer?
The Heat Factory warmer is a soft, lightweight pouch containing a biodegradable mixture of iron powder, charcoal, salt, sawdust and vermiculite. When exposed to the air, an oxidation process takes place that generates heat. Unopened, the Heat Factory warmers have a shelf life of three years or more. To find out more about the oxidation process that takes place in a warmer, take a look at Heat Factory’s article.
