WebRub the mineral across an unglazed white porcelain plate and describe the colour of the powder left on the plate, i.e. the streak. Notes : This is often a useful property for identifying opaque minerals which can have a streak … WebCleavage/fracture, along with density, hardness, and streak are among the most useful of the physical mineral tests. Often cleavage is so distinct that it can be used as THE diagnostic property for a given mineral species; muscovite with its perfect one-plane cleavage is a good example. Cleavage tendencies and patterns are also useful in the
