Revision as of 21:08, 4 November 2009

Wondering what that new kind of rock your dwarves just struck is good for? Possibly nothing, but when you're just getting started it can be tough to tell the trash from the treasure. The following table summarizes the types of stone and ore found in Dwarf Fortress (note that it does not include gems).

The Uses column lists any special uses or properties of this particular stone type; if no uses are listed, you can always use the stone for general construction and crafting. Note that many "low value" materials are still very useful in a Dwarf Fortress. "Colors" are useful for color coding or creative aesthetic uses.

For more detailed and expanded information, see the Stone, Ore, Metal, Alloy, Veins & Clusters, and Smelting pages, or the article on any particular stone, metal or ore.

Value of rocks & metals

You won't find the terms "low-value" or "highest-value" used in the game, but they're handy here for rough comparison. "Values" are all relative to each other, on a common scale. The "material value" number multiplies any final product that is created with that material by that number. An average generic statue (base value 25) is worth much more than an average generic throne (base value 10), but a throne carved from raw gold nuggets (10 x 30 = 300) will be worth far more than a common-stone statue (25 x 1 = 25). (Note - "quality" also factors in to total value of a final product, as do some other considerations, but those are outside the scope of this intro article). Bottom line - when in doubt, go for the more valuable stuff.

Common stones (the vast majority) have a value multiplier of x1, mid-value (all flux stones) are x2, and high-value (obsidian only) is x3. This affects things like stone tables and doors, statues or stonecrafts - anything made from stone. Metal ores have varying values, from 2-40, and can either be treated as stone or smelted into bars of metal.

(To be complete and for comparison, all wood has a value of x1, equal to common stone.)

For metals, low-value (like copper or nickel) is x2. Mid-value (silver or iron) is around x10, high-value (gold, steel) is x30, and highest-value (platinum, aluminum) is x40. Note that the raw mined ore and the smelted pure metal often have different value multipliers, but not always. Alloys like brass or bronze are often more valuable than the sum of their pure metal ingredients, and have a true spectrum of values between 3-23. (Alloy values are not listed in this article.) Metal can be crafted into weapons, armour or tools, decorations, furniture or even buildings.

Notes:

1. Adamantine is not exactly like other metals, although it works almost the same. It has a value multiplier of x300 (yes, three hundred). It is also superior to steel for all combat purposes, and steel is clearly the best material otherwise available. See adamantine for a full discussion of this unusual and ultimate material.
2. Bauxite: Magma will melt most stone, and while there are some magma-safe metals, mechanisms can only be made from stone (or processed adamantine), not metal. Bauxite (or adamantine) is the only stone that will not melt in magma (see magma-safe), and so is uniquely suited for that purpose.
3. % chance for additional metals - when Galena and Tetrahedrite are smelted, they produce (respectively) 1 lead or 1 copper bar, 100% of the time. They occasionally produce a second, additional bar of the second metal, with the % chance as listed above.
4. Ice has some very unusual properties in Dwarf Fortress, and can be disastrous if misused. See article on ice for a more complete discussion.

How to find a rock

Basically, you look under other rocks. The trick is to have a good guess which other rocks to look under to find the one type that you're looking for.

In the main article for every rock (many generic/low-value ones share another table on the stone page), there is information about where these stones can be found. Usually that's in a type of layer, or sometimes within another specific or general type of stone. Sometimes the rock is a layer stone. If it's found in sedimentary, igneous intrusive, igneous extrusive, metamorphic or soil, those are broad classifications that cover many different types of layer stone. A layer stone means it creates the dominant layer of that entire area, as defined by the "area block" (see next). By figuring out where the type of rock/ore you are looking for is found, you can dig in areas that have a better chance of having it.

Area Blocks

Okay, this is the "advanced basic" part of the lesson - then we're done.

When you first start a new game, and you're looking at the embark map, there is the World map on the right, the Region map in the middle, and the Local map on the left. The icons on the local map relate 1:1 to what are called "area blocks" on the game map, the map where your dwarves will move around. Each area block is 48x48 tiles square. The game is smart enough to make the borders a little fuzzy, but each area block defines the plant and animal life, the temperature and rainfall, and the layers of stones that can be found in that 48x48 area. These are clumped together in like types - using the F1, F2, F3 & etc. keys you can view them all.

If you pay attention to the pre-embark map (and make notes?), you can see what layers lie below each area block, in order as they go deeper. This will help you find stone/ore you might be looking for. You can also see where any underground pool or underground river or magma might be hiding - but that's another article.
