Copper and tin are called metals

Too Long; Didn't Read

“COPPER and tin are called metals,” continued Uncle Paul. “They are heavy, shining substances, which bear the blows of the hammer without breaking. They flatten, but do not break. There are still other substances which possess the considerable weight of copper and tin, as well as their brilliancy and resistance to blows. All these substances are called metals.” “Then lead, which is so heavy, is a metal too?” asked Emile. “Iron also, silver and gold?” queried his brother. “Yes, these substances and still others are metals. All have a peculiar brilliancy called metallic luster, but the color varies. Copper is red; gold, yellow; silver, iron, lead, tin, white, with a very slightly different shade one from another.”
