Silicon dioxide, also known as silica, is an oxide of silicon with the chemical formula SiO2, commonly found in nature as quartz. In many parts of the world, silica is the major constituent of sand. Silica is one of the most complex and abundant families of materials, existing as a compound of several minerals and as a synthetic product. Examples include fused quartz, fumed silica, opal, and aerogels. It is used in structural materials, microelectronics, and as components in the food and pharmaceutical industries. All forms are white or colorless, although impure samples can be colored.

Michigan (/ˈmɪʃɪɡən/) is a state in the Great Lakes region of the upper Midwestern United States. It has land borders with Wisconsin to the southwest, and Indiana and Ohio to the south, and Lakes Superior, Michigan, Huron, and Erie also connect it to the states of Minnesota and Illinois, and the Canadian province of Ontario. With a population of nearly 10.12 million and an area of nearly 97,000 sq mi (250,000 km2), Michigan is the 10th-largest state by population, the 11th-largest by area, and the largest by area east of the Mississippi River. Its capital is Lansing, and its largest city is Detroit. Metro Detroit is among the nation’s most populous and largest metropolitan economies. Its name derives from a gallicized variant of the original Ojibwe word ᒥᓯᑲᒥ (mishigami), meaning “large water” or “large lake”.
