Is gold better than copper
Many mistakenly believe that gold rings are a better conductor than water pipes because they are often used as face contacts. This is due to the fact that copper oxidizes, while gold absolutely does not, and copper oxide has a high resistivity. In a pair of contacts exposed to air, another thin layer of gold prevents the formation of large oxides. Copper has always been better.

When the hookah powder is heated in a porcelain bowl, the surface of the copper powder turns into a black coated substance, which is necessary for the formation of real estate oxide by surface oxidation. The black coloration is due to the formation of this copper(II) in oxide form when the copper comes into contact with certain air.
