What is the difference in streak between gold and Fool's Gold?
Gold will have a gold metallic streak, and Fool's Gold (pyrite) will have a greenish black streak.
What are the two best property tests to see if you have real gold or fool's gold?
One way would be to perform a streak test by sliding the sample across an unglazed tile with a little bit of pressure. Gold will have a gold colored streak and pyrite will have a greenish black streak. After exposure to flame, pyrite will have a slight sulfur smell which gold will not. == == == ==
What is the streak of platinum?
Yellow.
What did miners do after they found a place where they thought they could find gold?
If they were following a streak of visible gold they would follow that streak wherever it lead. If it was ore they would have it assayed and if rich enough in gold content they would start blasting and tunnel through whatever was in the way.
What is streak in chemistry?
When you scratch off a rock on an object and it leaves color. if it doesn't leave color then it does not have streak.(earth science)
What color is the streak of a pyrite?
the color of crushed pyrite is a greenish brown. Compared to gold which is gold.
What test is used to identify gold from pyrite?
When dragged across a streak plate, gold will leave a yellow streak, pyrite will leave a greenish-black streak. It is one way of differentiating gold from pyrite.
What is the difference in streak between gold and Fool's Gold?
Gold will have a gold metallic streak, and Fool's Gold (pyrite) will have a greenish black streak.
How streak is used to distinguish between gold and pyrite?
Gold will have a yellow metallic streak, pyrite will have a greenish-black 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.

How do you tell the difference between gold the metal and pyrite also known as fool's gold?
To tell the difference between pyrite and real gold, you can check the color and shape of the ore. Gold and pyrite have a yellowish color but pyrite has a pale and brassy color compared to gold. Pyrites are shaped more like crystals while gold tends to form as a nugget. Another difference between the two is that gold can be scratched with a pocketknife while pyrite cannot be scratched. You also can use the malleability and odor tests.
What is a streak when it comes to talking about science?
'streak' is the color that a mineral will leave when rubbed on a piece of unglazed porcelain. It is used to help identify the mineral. For example, arsenopyrite looks very similar to gold, but has a dark grey or black streak. Gold has a yellow streak.
How do I prove to my customers that my jewelry are real when I sell them at an antique farmers market?
Use a piece of unglazed ceramic material. Rub the gold against it. Fool's gold will leave a black streak, and real gold will leave a golden streak. This ofcourse works for gold and you will lose a bit of gold in the process. There are other methods for other metals and stones.
What is the physical property that is used to find if its pyrite or gold?
I would say streak (Is that a physical property?). Gold has a yellow streak, pyrite a very distinguishable greenish-black to brownish-black. [A streak is obtained by scratching a mineral (or rock) on a streak plate (a white plate made of porcelain (floor tile-like), with a hardness of around 6.5 (Mohs scale)] If streak is not a physical property I would say hardness: gold has a hardness of 2.5, pyrite of around 6. I'm sure there are other usuable physical properties, as density for ex.
What is the streak of platinum?
Yellow.
How can you tell the difference between gold and gold plated brass?
1. Gold is denser than brass: weigh the object, and determine its volume (e.g. by measuring the displacement when it is sunk into water in a graduated cylinder). Calculate the density. Gold will come out near 19.4 grams/cubic centimetre; brass near 8.6 g/cm3. 2. Rub against the unglazed ceramic object, real gold leave gold streak brass plated will leave brass streak.
