You could alternately use ammonia or ether, dissolve the cocaine hydrocloride in the liquid and gently evaporate off the liquid leaving you with purified base cocaine, be careful ether is explosive when heated (so is ammonia for that matter), this method will leave you with pure rocks which were what got people into smoking the shit to start with. Cocaine is about 4% average street purity, to cook with bicarb add 30% bicarb to mixture and wash this will result in a crack rock of about 2.5% purity, this is why people think crack is shit these days, two years ago an average crack rock would be at least double this.
