These unglazed porcelain tiles are ideal for streak testing of mineral samples. 

SIZE = 25mm x 50mm

The streak test is extremely useful in mineral identification.  Streak is the colour of a crushed mineral's powder.  As the colour of a mineral's powder may differ from the actual colour of the mineral, it is useful feature used in mineral identification.

To test for streak colour, swipe the mineral against the streak plate, but not hard enough to damage it.  The colour of the powder that results on the streak plate is the streak colour.

See mindat.org for information on streak for various minerals.

Easy to make your own streak plate but if you dont want the bother of finding the right type of tile, then these are cheap as chips to add in with some other items.
