Cast iron is iron or a ferrous alloy which has been heated until it liquifies, and is then poured into a mould to solidify. It is usually made from pig iron. The alloy constituents affect its colour when fractured: white cast iron has carbide impurities which allow cracks to pass straight through. Grey cast iron, or grey iron, has graphitic flakes which deflect a passing crack and initiate countless new cracks as the material breaks.

Carbon (C) and silicon (Si) are the main alloying elements, with the amount ranging from 2.1 to 4 wt% and 1 to 3 wt%, respectively. Iron alloys with less carbon content are known as steel. While this technically makes these base alloys ternary Fe-C-Si alloys, the principle of cast iron solidification is understood from the binary iron-carbon phase diagram. Since the compositions of most cast irons are around the eutectic point of the iron-carbon system, the melting temperatures closely correlate, usually ranging from 1,150 to 1,200 °C (2,102 to 2,192 °F), which is about 300 °C (572 °F) lower than the melting point of pure iron.

Iron (/ˈaɪərn/ EYE-ər-n) is a chemical element with the symbol Fe (from Latin: ferrum) and atomic number 26. It is a metal in the first transition series. It is the most common element (by mass) forming the planet Earth as a whole, forming much of Earth's outer and inner core. It is the fourth most common element in the Earth's crust. Iron's very common presence in rocky planets like Earth is due to its abundant production as a result of fusion in high-mass stars, where the production of nickel-56 (which decays to the most common isotope of iron) is the last nuclear fusion reaction that is exothermic. This causes radioactive nickel to become the last element to be produced before collapse of a supernova leads to the explosive events that scatter this precursor radionuclide of iron abundantly into space.

Like other group 8 elements, iron exists in a wide range of oxidation states, −2 to +8, although +2 and +3 are the most common. Elemental iron occurs in meteoroids and other low oxygen environments, but is reactive to oxygen and water. Fresh iron surfaces appear lustrous silvery-gray, but oxidize in normal air to give iron oxides, also known as rust. Unlike many other metals which form passivating oxide layers, iron oxides occupy more volume than iron metal, and thus iron oxides flake off and expose fresh surfaces for corrosion.

Martha Stewart (née Kostyra; August 3, 1941) is an American business magnate, author, magazine publisher, and television personality. As founder of Martha Stewart Living Omnimedia, she has gained success through a variety of business ventures, encompassing publishing, broadcasting, merchandising, and electronic commerce. She has written numerous bestselling books, is the publisher of the Martha Stewart Living magazine, and her syndicated talk show, Martha, is broadcast throughout the world.

In 2004, Stewart was entangled in the ImClone insider trading affair and there was speculation that the incident would effectively be the end of her media empire. She began a comeback campaign in 2005 and her company returned to profitability in 2006. Stewart rejoined the board of directors of Martha Stewart Living Omnimedia in 2011 and became chairman of her namesake company again in 2012.

Martha Stewart was born in Jersey City, New Jersey to middle-class Polish American parents, Edward "Eddie" Kostyra (c. 1912 – 1979) and Jadwiga Martha Ruszkowski Kostyra (b. September 16, 1914, Buffalo, New York – d. November 16, 2007, Norwalk, Connecticut). She lived in Jersey City until the age of 3, when her family moved to Nutley. She was raised in Nutley along with her five siblings. She took the name "Grace" for her confirmation name before graduating from Nutley High School.

Julia Child (née McWilliams; August 15, 1912 – August 13, 2004) was an American chef, author, and television personality. She is recognized for introducing French cuisine to the American public with her debut cookbook, Mastering the Art of French Cooking, and her subsequent television programs, the most notable of which was The French Chef, which premiered in 1963.

In 1996, Julia Child was ranked #46 on TV Guide's 50 Greatest TV Stars of All Time.

Child was born Julia Carolyn McWilliams in Pasadena, California, the daughter of John McWilliams, Jr., a Princeton University graduate and prominent land manager, and his wife, the former Julia Carolyn ("Caro") Weston, a paper-company heiress whose father, Byron Curtis Weston, served as lieutenant governor of Massachusetts. The eldest of three children, she had a brother, John III (1914–2002), and a sister, Dorothy Dean (1917–2006).

Child attended Westridge School, Polytechnic School from fourth grade to ninth grade, then The Katherine Branson School in Ross, California, which was at the time a boarding school. At six feet, two inches (1.88 m) tall, Child played tennis, golf, and basketball as a child and continued to play sports while attending Smith College, from which she graduated in 1934 with a major in English. A press release issued by Smith in 2004 states that her major was history.
