I used cotton instead of silica for this, but the very same method. The taste was fab and the vapor was magnificently creamy, but it really was a pain in the ... for just the reason Todd suggests: getting the cotton strands into the weensy holes is a nightmare.
I'm using mesh now, even though I don't like it nearly as much, just because I don't have the patience to go through all that torture all over again. I hope somebody comes up with a brilliant solution to this problem, because cotton really does produce a great
vape on this thing.
