anyone ever try to use Hydro-stone as a wick.i know when I use to smoke I used Hydro-stone to keep my tobacco moist the stuff wicks liquid good.Hydro-stone is a humidification stone made from baked Terracotta clay and is 100% natural and additive-free I think I might try it and see I know I droped my hydro stones many times and they never cracked or broke.
