Field Report : Can you fire proof valuables in drywall mud? - Page 3

TheGhostRider · 08-01-2009

Something to keep in mind...
The block still had moisture...
Moisture transfers heat so I would be inclined to think the the plastic jug deformed from a low dose of steam.
I higher moisture content will increase the chances of damage to the contents through heat transfer and conversion of moisture to steam.
Therefore it would be logical to do 2 experiments.
One using a high moisture content block with a plastic jug and paper and
one using a low/0 moisture content block with identical contents.
Keeping both blocks identical in shape and mass and identical contents with the only variable being moisture content would really show the difference.

Not sure if I'll do this experiment next, but I do agree that it would be very telling for overall understanding of effects of moisture or the lack there of on keeping the contents safe.

For the record. Drywall mud will not IMO protect anything substantially in a real hot fire, for very long. I don't believe it has any real heat resistant properties. I know that drywall (and joint compound) is considered by the NFPA to be combustable materials.

You could cast pretty much any shape including lids and what not with some saran-wrap and cooking spray. Add a wire loop handle and you have a $10 fire safe. I think if we could find a way to aerate the mud as it cured it would be a lot more protective. I don't know if a drill mounted mixer would do it or not, but it couldn't hurt.

maybe if you dried it layers?

Arch, thanks for trying this out. I had kind of forgotten about it and saw your thread just now. I'll Have to pick up a small bucket of wet mud and try it out in my burn barrel.

No problem and you're welcome. Next I think I'll try the same idea, but with sheets of drywall 3-5 layers thick see if that works.
