Glass is created when a molten material cools so rapidly that there is not enough time for a crystalline structure to form. To the scientist, crystals are materials that have their atoms arranged in perfectly ordered, lattice-like structures. In nature, glasses are formed when sand and/or rocks, often high in silica, are heated to high temperatures and then cooled rapidly. The Glass in Nature display shows specimens of glass made in nature. Obsidian or volcanic glass, for example, is molten rock that has quickly cooled, becoming rock in a glassy state. Tektites and Libyan Desert Glass are other forms of glassy rock created by the intense heat and force of meteoritic impacts on the earth millions of years ago. Fulgurites, which are made when strikes sand lightning, are brittle tubes of melted sand. Several types of Natural glasses are found in Sri Lanka. They come in different shapes and colors.
