I tried making myself a brew on the hexamine burner (Esbit clone)...no go.
The hexamine tablets simply refused to burn. After trying half a pack of matches, I tried with the bic lighter...nope.
I built a small fire on top of the hexamine tablets, using the spent matches, and lit those...nope.
I put a fist sized lump of balled upp newspaper on top of it...it burned away...but the hexamine did not catch fire.
I even poured denatured alcohol on it, and it burned out, without lighting the hexamine...
Glad this was in my front yard, and not out in the woods, as that would have been boring!
Anyone encountered this before?
And for the record, the heaximine was from an unoppened, still wrapped in plastic pack that has been sitting in the shed for 2-3 years...
