It means 'All Sea'; Panthalassa also known as the Panthalassic Ocean, was the vast global ocean that surrounded the supercontinent Pangaea, during the late Paleozoic and the early Mesozoic eras. It included the Pacific Ocean to the west and north and the Tethys Ocean to the southeast. It became the Pacific Ocean, following the closing of the Tethys basin and the breakup of Pangaea, which created the Atlantic, Arctic, and Indian Ocean basins. The Panthalassic is often called the Paleo-Pacific ("old Pacific") because the Pacific Ocean developed from it in the Mesozoic to the Present.

We generally see a smooth, shiny finish left on cookware so that food will be less likely to stick and so that it can be cleaned more easily. Certainly we encounter a lot of coatings on pans (like Teflon) to reduce food sticking, and some of these coatings are not smooth at all. But the metal pans work better when they present a smooth surface to the food. Food cannot "get into" irregularities on the cooking surface of the pan if it is nice and shiny (which is to say smooth and flat).
