One thing I noticed was that the tabs do seem to be smaller than the Esbit tabs...and definately smaller than the bars mentioned above. The instructions said they are reusable if you don't need a whole one but after a few minutes of burning, what isn't still solid or burned is in a pool of flaming liquid at the bottom...I didn't test what happens when you blow it out (liquidy mess? Stuck to the bottom like wax?). Based on my test I couldn't imagine using just one for anything.


Hmm, it sound like you have the being using poor quality hexamine tablets. The Esbits and even the cheaper ones from Hi-Gear (circular tabs) will not burn this way. It sounds as if a larger than normal quantity of the tablets binder is made from wax. The Esbit tablets have a more brittle crystaline texture and when they have completely burned there is very little residue. The residue, which is left is very small quantity of solid slightly sticky carbonised residue. There is no waxy or liquid residue left with good quality hexamine tablets.
