context1: These five-coloured ceramics are made in the finest and most sophisticated craftsmanship. Every piece of the ceramics is hand painted with a traditional Thai design. They come in plates, bowls, <strong>cups</strong>, <strong>jars</strong>, and tea sets
context2: Freshwater closed systems are often attempted by nature hobbyists and as experimental projects or demonstrations for biology classes. These require nothing more than a large glass <strong>jar</strong> with an airtight lid, a few <strong>cups</strong> of lake or river water, and mud or other substrate from the same body of water. Kept indoors at room temperatures, with exposure to sunlight from a window, such systems have been found to contain living organisms even after several years.
