Title: The lacquer coating defeats the purpose of using a copper bowl.
Review: Copper bowls with lacquer make them no different than regular plastic bowls.The coppper in real copper bowls helps create a tighter chemical bond in reactive sulfur items such as egg whites. The bond created is so tight that the sulfurs are prevented from reacting with any other material. This gives you the stiff peaks you're looking for. Cream of tartar does the same thing. Use a lacquered bowl and you might as well be using a cheap $5 plastic bowl.
