Alternatively, the free base can be obtained using an organic chemistry technique called trituration. Trituration of the free base from cocaine hydrochloride (or "cooking") is done by dissolving the cocaine hydrochloride in water over constant heat, while simultaneously adding a base (such as baking soda ) to form the free base cocaine.
Pictured here are baking soda, a commonly used base in making crack, a metal spoon, a tealight, and a cigarette lighter. The spoon is held over the heat source to "cook" the cocaine into crack. Sodium bicarbonate (NaHCO 3, common baking soda) is a base used in the preparation of crack, although other weak bases may substitute for it. [7] [8]
