On my lab tests the 12 strand hemp twine wicked "capillary action" better than any other wick and that included your yarn, silica, cotton, and SS.
Just got my ball of rawganique's TW12B400 12 ply, 400 foot, Fine Hemp Twine...
Now I just need to pull off 50 feet or so and get to boiling
Gonna make the first test on my IGO-L, and if that works, I'm thinking of using it on my AGA-T+ either alone, or as a flavor wick alongside the wire mesh...
Any suggestions?
