This test simply involves one, scratching the surface of the tile with a particular rock or mineral, the coloured streak left behind then assists the user in determining the mineral, or minerals within a rock sample. (See below a list of some common minerals and their streak colours). The tiles are made from porcelain, a strong, tough material and also has a matt finish and a very slight, fine textured surface. The white coloured streak plates are ideal when observing dark coloured minerals, ones which streak may not show up or otherwise be too difficult to observe on a black streak plate. Each plate measures 45 x 45 mm each and come supplied single with discounts available on quantities.
