After reading the post about the corrosive nature of the Weber Fire Cubes, some testing is needed. I have been storing them in a plastic sealed box with butane lighters. I will watch the metal in the lighters to see if they corrode. Maybe I should come up with some other method of making a timed explosive. To get a running start, some advise from a chemist would be of help.

What flammable compound such as wax, Snow Seal, Duco Cement, Gorilla Glue, hot glue or the like, could be used to seal Weber Cubes or trioxane for long term storage?

I think you may need to not only seal them but also vacuum pack them. In my experience contact with air will cause them to degrade, and fairly quickly. It seems the volatile, flammable part just "evaporates" away, leaving a very light, crumbly cube that doesn't want to light very well.

Thank you for reminding me. Here's yet another product that's staying off my "To Get" list.

Wrap in a couple of layers of wax paper and seal into a durable air-tight package by overlaying with foil tape, if your hard-core get the stainless foil tape, assembled sticky side to sticky side while pressing out the air with your fingers. If it doesn't decompose on its own that sot of packaging should last for years.

Ive done this with lighters and matches and they show no deterioration after a decade. How it works on solid fuel materials is still up in the air but for matches and lighters it seems to last indefinitely.

The foil tape is available at any hardware store and is sold for permanently sealing duct work. You want the stuff that has a waxed white backing tape over the acrylic adhesive. Not the regular duct tape.

As Cheap as that stuff is,I'd say It isn't Worth The Hassle!Tinder quiks&Fat wood strips,Package smaller & Last a Long Time!

Fire Paste by Coghlan's..it comes in a sealed tube.they did all that work for you.i've tried a bunch of fire lighters and that works best.cheap and a tube used a lot,i use it to light birch bark which is over kill,will last weeks.it's fun to try stuff out but when there is a product out there that works i go with it and not reinvent the wheel.

The best way to deal with the fire cube problem is to throw them away (or burn them) and replace them with vaseline-infused cotton balls. Problem solved.
