This set of 40 white and 40 black streak plates is an economical option for teachers, geologists, or students, and is excellent to have on hand in an earth science classroom. Streak plates allow you to test the hardness of softness of minerals, as well as their streak color. By scratching the mineral in question against the plates, students or teachers can determine these properties by observing the quantity and hue of the residue left behind. White streak plates are intended for darker or colorful minerals, while the black streak plates are ideal for lighter-colored minerals.
