Are you serious? Crack is cocaine. The cocaine you buy ithat is lumpy powder and shiny is cocaine hcl. It has that acid attached to it which changes it a lot chemically. If you use a base and neutralize that acid then it is gone and you have (freebase) cocaine. Cocaine base. Base cocaine. The 2 most popular methods are to use ammonia, a poisonous gas, dissolved in water ( it's ph is basic) and the other method is using sodium bicarbonate or carbonate, both basic in ph. People call the product of bicarbonate and carbonate Crack. It's usually a more crude product than the ammonia method but that's a result of the extra steps required to get the poison ammonia out of it and crack can be just as pure as freebase cocaine if you clean it. I've made it on the stove, in the microwave, in a spoon and on the bottom of a popcan. I've probably done it other ways also
