To measure the streak color of a mineral, the first step is to obtain a sample of the mineral you want to test.
Step 2, find a nice, clean ceramic tile with a white unglazed back.
Step 3, using a corner of your mineral, move it across the back of the tile while pushing down enough to see the streak and its color.
Step 4, compare the streak color with samples of known minerals, from color photos in a book of minerals, or from a written description of minerals and their streak colors.
