[Stoves] Testing glues for briquettes

[George Riegg Gambia]

dear frank, crispin, robert and all of you

sorry frank to be a pedant. i'm a poor guy. in the field. working with other
poor guys. all we have most of the time is a press, a few buckets, some
stout sticks, lots of stufff lying about we're trying to keep together until
it's dry to move it from here to there. nobody ever here has seen any of the
gear you are describing but we all can drop a brick from a certain height.
it doesn't look as scientific but in practical terms it's more realistic if
we all can agree on the baselines.

cheers
george from the jungle
