Rubbing the mineral against an unglazed ceramic tile, called a streak plate, leaves a streak of the powdered mineral. This powder reflects the true color of the mineral. It's called a streak test, and the resultant line of color is called the streak. A link can be found below to check facts and learn more.

∙ 13y agoColor; minerals that look similar or identical can be "streak tested," as it is called, to determine if they are the same color. One example is gold and pyrite; gold leaves a golden scratch while pyrite has a greenish-yellow scratch.

∙ 15y agoYou're looking for the word "Streak".
This means you are testing for the 'raw' colour of the powered mineral, which ceases to have a crystalline structure. This allows for the comparison of minerals that have some variability of colour (such as hematite, which can be a dark red, black, or shiny-silvery colour). This is a more accurate way of describing an unidentified mineral than to use it's physical colour appearance, and can be used to identify some minerals. Use caution when using this method, as some minerals are in fact HARDER than the porcelain(which has a Moh's hardness of about 7), and the porcelain will come off onto the mineral producing a false 'white' streak.

How can an unglazed porcelain tile be used to identify a mineral?
You identify minerals through a streak test. This involves taking the tile and the mineral to be identified and rubbing them together. This produces a colored streak on the tile, which can be used to identify the mineral. Consult a field guide for specific colors.

What is a streak plate?
A streak plate is a surface of unglazed ceramic, used to find the true color of a mineral specimen by drawing the specimen across it. The color of the resultant powder is referred to as the streak or streak color of a mineral.
Why are streak tests used?
Streak tests are used to identify minerals. Rubbing a mineral specimen against unglazed white porcelain, or finely powdering it and examining the powder against a white background, is a useful diagnostic test in some cases. Eg. hematite, a black mineral that looks much like many other black minerals, has a distinctive red streak.
How Color of the same is all that is needed to distinguish between real gold and fool 's gold?
The color of pyrite and gold are different in the powdered state achieved by rubbing an edge of the mineral against an unglazed tile. This color is called the mineral's streak. Gold will have a shiny gold streak and pyrite will have a blackish green streak.
