when do iron chefs learn the secret ingredient
Iron Chef America Unlike Iron Chef, where chefs had roughly 5 minutes to discuss their strategy before the battle begins, the revelation of the theme ingredient occurs 45 minutes before the start of the battle. However, this segment is not shown on television, and it is a common assumption that the battle starts immediately after the secret ingredient is revealed. This practice was described on an episode of Unwrapped.
Iron(III) oxide Iron(III) oxide or ferric oxide is the inorganic compound with the formula Fe2O3. It is one of the three main oxides of iron, the other two being iron(II) oxide (FeO), which is rare, and iron(II,III) oxide (Fe3O4), which also occurs naturally as the mineral magnetite. As the mineral known as hematite, Fe2O3 is the main source of iron for the steel industry. Fe2O3 is ferromagnetic[citation needed], dark red, and readily attacked by acids. Iron(III) oxide is often called rust, and to some extent this label is useful, because rust shares several properties and has a similar composition. To a chemist, rust is considered an ill-defined material, described as hydrated ferric oxide.[citation needed]
