Black gold is slang for crude oil.
Yes, Black Gold was a real horse who won the 50th Kentucky Derby.
No, real gold does not turn black when you burn it. When heated, gold will retain its color and may become softer or deform, but it will not change color like other metals that oxidize when burned.
Two methods to tell real gold from fools gold are:Rub the piece of gold against a piece of unglazed ceramic material. If it is real, it will leave a golden mark while fools gold will leave a black mark.Apply nitric acid to the gold. If it dissolves, then it is obviously fake, as real gold cannot be dissolved in nitric acid.
It means that it's cheap, not real gold or that the gold plating is so thin that it's wearing off.
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. == == == ==
When a gold necklace is burned, it can result in the formation of black soot due to the impurities present in the gold or the materials used in making the necklace. However, genuine gold does not change its chemical properties when burned and will not turn black.

Gold is an element. Only gold is real gold.
To determine if gold nuggets are real, you can perform a few simple tests. First, check for a metallic luster and a weight that feels heavy for its size, as gold is denser than most other materials. You can also conduct a scratch test on a ceramic plate; real gold will leave a gold streak, while fake gold will leave a black mark. Lastly, use a magnet; real gold is not magnetic, so if the nugget is attracted to the magnet, it likely contains no gold.

Since black gold is oil, yes there is black gold in the world.
Finding fool's gold (pyrite) in a creek does not guarantee the presence of real gold. It is possible that real gold could be present in the creek, but you would need to test the area further to confirm. Look for indicator minerals like black sand or other heavy minerals that often accompany gold deposits. Consider researching the geology of the area or consulting with a local geologist to increase your chances of finding gold. Happy panning!
