Introduction to the Stone Industry
A considerable industry centered on the use of stone is essential for any fortress. The stone industry is based on the use of loose stone (aka boulders), which are the residual products of mining, as the raw material for all of its products. The stone industry is essential for fortress development, as both a source of revenue through trade, and as a source of material and items critical for building and construction.
The industry produces a variety of items under the following categories:
- Constructions
- Furniture and items used in buildings
- Mechanisms
- Crafts
- Stone Containers
These items are created by masons, mechanics, and stone crafters, each in their specific workshops.
Procuring Stone
Stone can come from three places
- Mining. Loose stone and boulders are a byproduct of mining. There is a 25% chance that section of natural stone that is mined will produce a stone boulder.
- Trade. Stone can be purchased at the trade depot from visiting caravans. Specific types of stone can also be requested from the liaison, provided that the home civilization or trading race has access to it.
- Embark. Stone can be purchased at embark. This is a very good idea if embarking on an aquifer, as it may be difficult to obtain any stone to start with.
Labor, Skill, and Workshops
The stone industry relies on the following labors:
- Mining - to procure the stone / boulders.
- Stone Hauling - to bring the stone to stockpiles and/or workshops. (Refuse hauling if using quantum stockpiles.)
- Masonry - to build furniture, blocks, and to build constructions.
- Mechanic - to build stone mechanisms
- Stone crafter - to build stone crafts and containers, including nest boxes, hives, and stone short swords (requires obsidian).
Masons are typically in high demand, as they do double duty working on constructions as well as creating items from the mason's workshop. As a fortress grows, the demand for furniture will remain very high, and if you are building many constructions that require walls, stairs, ramps, and bridges, you will need several mason's to meet the demand. Stone blocks are a much more efficient way to build constructions as opposed to boulders, both in terms of maximum utilization of stone (4 blocks are created from 1 stone boulder), and for speed of movement (blocks are hauled much faster than boulders, and are stored in bins at 5 per bin). A good way to increase the skill of your novice Masons is to have them mass produce stone blocks.
There are three workshops that can utilize stone as the primary material for all that they build:
A mason's workshop produces stone blocks (which are highly useful for construction); furniture including tables and thrones (chairs), storage items including coffers (chest), cabinets, weapon racks, and armor stands; portals including doors, grates, hatch covers, and flood gates, funeral items including slabs and coffins, milling items including querns and millstones, and finally stone statues.
- Masons are not able to build pipe sections, cages, beds, buckets, and bins, as well as barrels, but large stone pots (which are arguably superior to barrels) can be made by a stone crafter at a craftsdwarf's workshop.
- Querns, slabs, and millstones can only be made with stone at a mason's workshop.
- Stone blocks are a much more efficient way of building constructions, and are useful in leveling a novice mason's skill. Blocks are stored in bins (5 blocks per bin).
A mechanic's workshop produces mechanisms and traction benches. High value mechanisms can be a good source of income early on.
- Mechanisms may also be made of metal, which is useful when creating mechanisms of high value, but general purpose mechanism are best made from stone.
- It is good practice to make mechanisms from magma safe stone. This will prevent building deconstruction, provided all components are made from magma safe material, should the building come into contact with magma.
A craftsdwarf's workshop produces stone crafts including toys, musical instruments, and mugs (goblets); containers including stone jugs and large pots; as well as nest boxes and bee hives.
- All crafts can be created using glass, and in some cases ceramics, which have higher base values, but require more effort to create.
Value & Quality
Stone typically has three base levels of value. The vast majority of stone has a base value of 1, while flux stone (limestone, dolomite, chalk, and marble) has a base value of 2, and obsidian has a base value of 3. These values serve as multipliers to the overall value of any item produced using them, so say a statue with a base value of 25, made of marble, will be worth 50, and if made from obsidian, will be worth 75.
The quality of items produced increases with the skill level of the labor assigned, such that highly skilled masons, stone crafters, or mechanics, will produce high quality items. Quality is also a multiplier on base value, such that stone items created using Flux Stone or Obsidian will experience considerable increase in overall value.
Stone Management (Logistics)
For a detailed article on managing the movement and stockpiling of stone, read stone management.
Managing your stone resources & products is a tricky, and potentially time consuming business. Stone hauling is notoriously slow, and can tie up many haulers for long periods of time if you don't carefully manage your hauling & stockpiling. Controlling production is also tricky, as designating the specific kinds of stone used for production requires customized (by stone type) directional stockpiling that feed designated workshops. Based on the variety of items and uses created, you will also need well organized output stockpiles, so that your trade, construction, and building items can be isolated to their most useful locations.
A typical fortress will have anywhere from 6-12 specific types of layer stone, which make up the bulk quantity of stone on a given Z-layer. There are 25 types of layer stone, of which 7 are magma safe. The four types of Flux stone are layer stone, so a flux stone is present on the embark location, it should likely be available in good quantity. Layer stone is usually grey or grey-green in color. Supplementing the layer stones will be veins and clusters of secondary types of stone which include all non-flux economic stone types. Each secondary stone is directly associated with a particular layer stone. These are typically low value stones, however, they provide a wide variety of color, and several of them are magma safe. For every layer stone in an embark, there is at least one if not 2-3 secondary stone types. As can be seen, managing all of the various types of stone requires deliberate planning and consideration.
One approach to managing intake is to organize your stockpiles by the following categories: low value stone (1), medium value stone (flux -2), high value stone (obsidian - 3), and magma safe stone. See The Non-Dwarf's Guide to Rock for further details. Note that this method is not useful if you want to control furniture building by color. For that level of detail individual stockpiles by each stone type may be required. Link your magma safe stone to feed your Mechanic Workshops, and any Mason Workshops that you want to produce blocks (for magma safe constructions.) Link your medium and high value stone to feed your Craftsdwarf's workshops and Mason Workshops to produce furniture and crafts of high trade value. Low value stone can be linked to workshops who will be operated by low skill, novice level dwarves.
Obsidian - the Premier Stone
Obsidian deserves special mention as it is the highest value stone in the game (3). It is unique in that it can be farmed using magma and water, and it can be used to create obsidian short swords. It is magma safe, and due to its high value, is considered to be the best stone to use when attempting to craft objects designed to improve your dwarves' mood and create happy thoughts. In particular, obsidian mechanisms will achieve the highest possible value of any stone based mechanism.
Tips
After your fortress has been dug out you will likely have more stone than you know what to do with. A good idea is to produce stone crafts for when the first dwarven caravan arrives. Crafts often produce light goods. The stone is also useful as it can produce most furniture. Finally, the stone can be used in constructions.
If you are lucky enough to have layers of flux stone in your fortress, any goods produced with them will be twice as valuable as other goods of default (non-flux stone) quality. Obsidian will enhance goods to triple value.
Stone cannot be used to produce beds, bins or barrels. However, large stone pots are functionally the same as barrels, and can be traded to the tree-fondling hippies elves.
