Answer 2

luster zinc or chromium or tin​

Explanation:

• To give a polished mirror finish to steel, chromium plating can be used.
• The art of silvering, tinning, and gliding is a very commonly used method of providing metallic luster (shine).
• Metallic precipitates are obtained, that is a substance exerts power in uniting itself to the solvents and the metals are thus deoxidated, which fall down in the pure or regular state.
• Metals have shine which are opaque as well good conductors of heat, but these properties have nothing to do with them being used to make locks.
