Quickest way to blacken copper is using a sulphur solution For those who are looking to turn copper black go to an art supply store and ask for Liver Of Sulphur. It will blacken copper almost instantaneously. Test on a corner or a scrap first to give you an idea as to how fast it will take effect. Also make sure your copper is not coated with a lacquer and make sure to use in a well ventilated area (the fumes are not toxic but, being sulphur, the smell is very unpleasant)

What happens when you burn copper?
When copper gets burned, its own identity vanishes and it changes into a black coloured powdery substance. This substance is copper oxide. The reaction is as follows:- 2Cu(s) + O2(g) ------> 2CuO(s)
What is the name of the black substance formed on copper?
The black substance formed on copper is called copper oxide. It is a chemical compound that forms when copper is exposed to oxygen in the air, resulting in a black or greenish-black tarnish on the surface of the copper.
What is the color of copper carbonate when heated?
When copper carbonate is heated, it changes from its green color to black copper oxide.
How does black copper oxide form?
CuCO3 + Heat --> CuO + O2 Green Copper Carbonate when heated will form Copper Oxide and Oxygen
Which salt changes from green to black on heating?
Copper(II) sulfate changes from green to black when heated due to the decomposition of copper(II) ions to copper(I) ions, which are black in color.
Does burning copper in a naked flame increase its weight?
Copper doesn't burn in a naked flame, but will simply turn black. This is due to its reaction with the oxygen in the air forming black copper (II) oxide CuO. Therefore, as the copper has now reacted with oxygen it will weigh more than it did.
Does copper metal burn?
Yes, at a high enough temperature Copper will burn and combine with Oxygen to form Copper oxide.

What happen when copper is burn?
The copper oxides (CuO and Cu2O) are obtained.
What is the name of the black substance formed on copper?
The black substance formed on copper is called copper oxide. It is a chemical compound that forms when copper is exposed to oxygen in the air, resulting in a black or greenish-black tarnish on the surface of the copper.
What happens if you burn copper?
it will just burn. That's the science behind the question.
Does copper sulfate burn?
No. It is a nonflammable salt.
What is the name of the black coating that forms on the surface of the copper?
The black coating that forms on the surface of copper is called copper oxide.
What does copper oxide look like after copper has burned?
Copper oxide appears as a black or dark brown powder after copper has burned.
What would you get if you crossed a black copper maran with a black silkie chicken?
A silky black copper chicken.
What is the color of copper carbonate when heated?
When copper carbonate is heated, it changes from its green color to black copper oxide.
How does black copper oxide form?
