Warning-Fire Danger-Potential 4 gram lid?

WARNING-FIRE DANGER

With the heads-up from Adam and Todd I did some fire testing of the Yuban foil-looking inner lid..

When placed on top of my burning pocket rocket stove burner this lid quickly caught fire, burned in an evil way and started to disintegrate.  Here are a couple photos:God only knows what it is made of.  Looked like simple foil to me but the looks were deceiving.  I can’t even recommend it for non-stove use because it looks so stove-worthy someone will eventually put it on a stove or fire of some type.

Daryl,

Note to self….do more testing before going public with your stupid ideas.

Heh I just commented on this in your test post. I’ve used one of these from a can of smoked almonds as a lid with my MLD 475 cup and as a ground heat reflector with other cooksets for a long time. The foil has a nice thickness to it and lasts a long time.

Nice idea.  A bit more substantial than aluminum foil alone, yet very minimal.

Nutella and some kinds of peanut butter have a similar metallic foil liners that you remove before your first use.  Smaller in diameter than the large coffee containers.

[Adam Kilpatrick]

This is a great idea.  I see these kinds of seals all the time. Unfortunately I think most of the ones I see in Australia are a combination of foil on the top and some kind of paper/plastic on the bottom. Will keep my eye out though.

I have been in using the same one for over three years as a ground protector for my alcohol stove very durable.

I love these.

I have used variations of ’em for awhile because they’re so light and durable.

Caveat: some have a “plasic-like” coating that can melt off and once I burned my fingers lifting it because heat up the side of the pot melted it and … WHOA!  Not a good surprise.

PENANCE

As penance for my error I’ve sent private warning messages to each of you who posted here.

Monday I plan to send out a warning pulled by the Goodyear Blimp.

[Colin Parkinson]

Mine was pure aluminum.  You need to check before use.

[Matthew / BPL]

Thanks for sending the sending the PMs. I think mine is 100% aluminum. I looked for it this afternoon and couldn’t figure out where I have cleverly stashed it at the moment so it may not be an issue…

[Adam Kilpatrick]

Good due diligence Daryl.

Some might still be ok… but some might have flammable bits attached to them and not just be pure aluminium. So, if you want to go down this route, test them carefully before taking into the field.

Note, by carefully, I suggest:

Safely in a nice fireproof location

Over and above what it would experience in normal conditions on your stove. Hold it with a pair of long grippers (or something), and put right in the heart of the flame of your stove. Pull away as soon as it starts to burn or melt (don’t get material on your stove).

AT YOUR OWN RISK.

“put it right in the heart of the flame of your stove”

I agree.  That’s what I did and the results were evident immediately.
