paraphrasing

can anyone paraphrase this for me??????

Even though it’s a “gold” penny, the US Treasury has a little problem with people trying to buy something with gold pennies. In 1983, the US Treasury started making pennies with a zinc core with a copper coating... turns out they weigh less and cost less to make than their pre-1983 counterparts, which were made with an alloy of 95% copper and 5% zinc. In this activity, soaking the penny in the zinc solution actually coated the surface of the penny with zinc atoms. When the zinc covered penny was heated, the copper atoms of the penny and the zinc atoms coating the penny mixed and turned gold in color. This mixing of metals is an alloy called “yellow brass.”

Artists often work with alloys like bronze, steel, or brass because of their durability and color. Bronze is a mixture of copper and tin. Brass, made in the activity above, is a mixture of zinc and copper. Steel is made of iron and carbon. Alloys are used to make coins, jewelry, sculptures, and other items.
