Metallurgy

Gold is found "native" across much of the world, and can be worked with a stone hammer and anvil alone. It is considered by historians such as Badjur Gidu of Karuwehrr to be the "first metal".

Though not often found in as pure a form as gold, silver and copper can also be beaten into shape with little heat.

Easier to find and work than iron ore, meteoritic iron is still the primary source of the metal for people such as the Yanik and the Gira (who rely on an iron-nickel meteorite field in the highlands).

Chrysochalcum, an alloy of gold and copper, is very popular among the Eya people and in the kingdom of Gimgaranka.

A naturally-occurring alloy of gold and silver, electrum often has a greenish-yellow tint to it.

A mixture of tin and zinc, brass is quite effective in the creation of statues and medicinal containers. It is most popular in Temacan and Yashdar, as well as Greater Oma and Nukambi (where it is also used to make musical instruments).

Mercury, more typically called quicksilver, is not used in alloys, but is a key component in making amalgams of metals for gilding.

A copper-nickel alloy, white copper (first developed in Yashdar) is mostly used in coinage, but has excellent potential for maritime applications.

Arsenical bronze, often derived from naturally-occurring ores, has a silvery tint to it, and hardens with work better than copper on its own.

As arsenical bronze is to copper, so tin bronze is to arsenical bronze, and easier (and less poisonous) to work—but the tin itself is rarer.

An iron alloy with a low carbon content, wrought iron is made in bloomeries. Magnetite ores are quite similar to the finished result, and are preferred in southern Yandjee.

Bone iron is derived from the iron-producing bacteria found in the swamps of northern and eastern Aion, mixed with ground bones and charcoal and set in a bloomery.

Crude iron, instead of being made in a bloomery, requires a blast furnace. It can be used to make cast iron, which has use in kitchenware and architecture.

Steel itself is made by mixing carbon with iron; crucible steel is made by mixing crude iron with iron ore (and sometimes steel) with sand, glass, ashes, and other fluxes in a crucible. It has much use in cutting tools, cannons, and precision instruments.

Ripplework has its origins in Sayintha, as a form of crucible steel with swirling patterns inherent to the metal, with carbon content from treegrass. Particularly useful in the making of weapons.
