The history of mead goes back more than 8,000 years. The oldest known meads were created on the Island of Crete; fermented honey was seen as an entheogen and bees were sacred to Demeter. Wine had not yet been created. Mead was the drink of the Age of Gold, and the word for drunk in classical Greek remained "honey-intoxicated." (Kerenyi 1976 pp 35ff). Mead was once very popular in Northern Europe, often produced by monks in monasteries in areas where grapes could not be grown. It faded in popularity, however, once wine imports became e ...

Many credible sources attribute the invention of black powder (火藥, huo3 yao4; lit. fire medicine) to ancient China in the 9th century during the late Tang dynasty (618 - 907 CE). The invention appears to have been made accidentally, by Taoist alchemists seeking the elixir of immortality, or possibly as a fire starter for the easy ignition of tinder by sparks. The first references to gunpowder appear as warnings in alchemy texts not to mix certain materials together. However these early mixtures contain large amounts of inco ...

Mead can have a wide range of flavors, depending on the source of the honey, additives called "adjuncts" or "gruit" (including fruit and spices), yeast employed during fermentation, and aging procedure. Mead can be difficult to find commercially, though some producers have been successful marketing it. Some meads retain some measure of the sweetness of the original honey, and some can even be considered as dessert wines. Drier meads are also available, and some producers offer sparkling meads, which (like champagne) can make for a del ...

Black powder consists of the granular ingredients sulphur (S), charcoal (provides carbon to the reaction) and saltpetre (saltpetre, potassium nitrate, KNO3; provides oxygen to the reaction). A simple, commonly cited, chemical equation for the combustion of black powder is: 2 KNO3 + S + 3C → K2S + N2 + 3CO2 A more accurate, but still simplified[1], equation is 10 KNO3 + 3S + 8C → 2K2CO3 + 3K2SO4See also:
