The chemist observes the "zone of precipitation" under a microscope. The speed of crystal growth and the final geometric shape (e.g., rhombs, sheaves, or stars) are the primary identifiers.
A drop of the specific reagent is added to the edge of the sample.
A small drop of the alkaloid solution (usually in a weak acid like hydrochloric acid) is placed on a glass slide.
