Other - Cotton wool as a filter?

[freakymonkey]

Hello, SWIM has been browsing this site for a few months and obtained the instructions for CWE through here. First of all thankyou for all the advice so far that SWIM has read.

SWIM was wondering about using a bit of cotton wool in a funnel to filter the codeine instead of coffee paper. SWIM had read elsewhere that someone uses this method effectively but cannot find any more information on it.

COULD anyone else help gather info?

A side question but what does each CWE yield (first filter, SWIM does attempt to extract more from the gloop). SWIM is sure she read the yeild somewhere but can't find it again. It is just a curiosity.

Nevermind the second question, SWIM has just found a yeild thread. First question still stands.
