literally, it just soaks into the pores of the glass.

Constant torching makes the glass porous from the reheating and cooling. You can torch it when necessary but always clean it with the q-tip first and leave the meth residue slightly moist so it burns off easier. Make sure you clean your glass piece after every bowl with a q-tip and saliva or water. It was awesome but I was new to smoking and cleaned it with a torch to often which ruined it. DO not use foil, wastes your dope and the aluminum is horrible, far worse than the dope for you. Then keep torching till the hole smooths out.

Once you have your round bubble end, heat one point with the torch grazing the edge horizontally above the bubble when it is red hot keep the fire to the spot and blow until the hole pops. Blow into the end, not hard enough to pop it but with enough strength for it to expand into a bubble. A glass cigar tube heated till glowing red from a torch.
