Melts when properly treated, very bitter if not well used. Found in many states ranging from virgin metal to common ore. In its natural state the specimen varies considerably, but is often changed artificially so well that the change is indiscernible except to the experienced eye. May give violent reaction if left alone. Will absorb great amount of food matter.
Reaction accelerates out of control when in dark and all reaction conditions are suitable.
Extremely difficult to react if tin the highly stable pure form. Yields to pressure applied to correct points. The reaction is highly exothermic. The best results are obtained between the ages of 18 and 25 years. Used as a tonic for low spirits.
