Halite hardness

Description and Identifying Characteristics Halite’s most distinctive characteristic is its salty taste. For practical and sanitary reasons, you probably should not test the taste of a mineral sample by directly licking the sample. Instead, moisten your finger, rub the sample and then taste the residue left on your finger.
