▶ This is some information on why copper mugs and Moscow Mule cups are lined with nickel.
▶ Copper is a heavy metal and liquids placed inside a copper cup will absorb some of the copper. You will then injest it while you drink which can be hazardous to your health. For these reasons many manufacturers produce lined mugs to prevent the ingestion of heavy metals.
▶ The first reason is a functional reason. The copper mug is a temperature regulator. It keeps things colder longer but copper is a relatively soft metal and can be damaged somewhat easily. Nickel or in some cases stainless steel is used to line the inside of the cups to increase strength and durability and extend the useful life of the cup.
▶ The second reason copper mugs have an interior nickel liner is that copper is a heavy metal that can leech into the fluids contained within the walls of the cup. Because copper can build up in the body to unhealthy and potentially dangerous levels copper mugs needs to be lined with a metal that won’t deposit itself into your drink.
▶ Although the body regularly has some copper in it the element doesn’t go away easily and if levels continue increasing you can get really sick. When they get too high copper can cause hospitalization or even death. It would be foolish to drink regularly from a copper mug that didn’t have a protective layer built into it.
