Observing and Describing Key Characteristics
Halite: Tastes like salt, because it is salt. Halite has a cubic crystal form, so it cleaves into perfect cubes. It has roughly the same hardness as calcite, and is colorless. Although taste is an important characteristic, caution students to avoid tasting minerals; some minerals have very unpleasant tastes.
Halite - Wikipedia
Halite (/ ˈ h æ l aɪ t / or / ˈ h eɪ l aɪ t /), commonly known as rock salt, is a type of salt, the mineral (natural) form of sodium chloride (Na Cl). Halite forms isometric crystals.

Properties of Minerals Crystal Habits
Properties of Minerals Crystal Habits Not all mineralogical samples form nicely shaped crystals but, when they do, the shape can be helpful in identifying the mineral. The habit of a crystal refers to its shape. (But, it refers only to the shape that the crystal forms as it grows, not as it breaks--see next section of cleavage and fracture.) For example, some minerals such as halite tend to be ...
