Important note to High altitude and dessert use of them, they require both oxygen and moisture to work.
Had to show my brother this, 7500 feet + New Mexico means thin air and next to no humidity. Mildly wetting the warmer made it work. |

Vermiculite is also used for a variety of industrial purposes and is found in a variety of products.

Zorro, good point. I've had trouble with them in NM without any moisture.

"If you inhale water it's definitely hazardous and an irritant for your lungs."
You inhale water with every breath you take. It's called humidity.

Spy,
Take a look at some of the chemicals used in hydroponic gardening. There are a whole lot of them I am not real interested in having around. Since everyone wanted to claim it was safe and didn't give what I considered a solid argument about it I decided to look it up. It seems in many vermiculite mines asbestos is also present. This issue has been resolved for the most part with those mines being idled since the early 90s, so it shouldn't be an issue for any newly produced items. There seem to be no other known health risks. Of course, I think asbestos was held in high regard as a naturally occurring silicates with desirable properties and no health risk for about 75 years. Oops. How old are MSDS sheets? Can we dig up an old one for asbestos? I have a small yard that is surrounded by concrete on all sides. I started pouring out the hand warmers there. I will see if there is any appreciable difference over time. |

I use vermiculite often, it's in every potted plant. So look out its everywhere. Basically harmless, could have a remote possibly of have a trace amount of asbestos. Higher concentrations in more of your household items than in vermiculite. It's natural and it won't hurt to throw away.
Great high temp insulation for outdoor ovens and small back yard forges.

I've tried different brands. For several years I've used only Hot Hands in gloves, socks and rarely in a waist band or pockets. They definitely help me tolerate colder weather when hunting from a tree stand.

When its real cold I use the hot hands in my gloves and the toasty toes are attached to the bottom of my toes. I think they do help for sure.
Wal-Mart sells them of course. |
