There are a lot of hasit (station contact ta) old, and there seems to be something called bronze water that can be aged in cs104 (station contact ta)? Cultural relics counterfeiting?

It is possible that the copper incense burner is an alloy, and the heating process Cu is enriched on the surface, which is equivalent to the regional smelting method.

There is also a possibility that the cu enriched to the surface generates cu2oliuershiyi (station contact ta) is actually very simple... You put it in the copper sulphate solution.

Inside, make a galvanic battery... After a while, it will turn red... The color of copper even... Purity ゼンンング (station contact み) heating oxidation is possible

Faded in the wind and sun.
