A defeated gabbro man will leave behind one gabbro and a defeated magma man will leave behind one obsidian. This is a very good idea if embarking on an aquifer, as it may be difficult to obtain any stone to start with. Specific types of stone can also be requested from the liaison, provided that the home civilization or trading race has access to it. Stone can be purchased at the trade depot from visiting caravans. There is a 25% chance that section of natural stone that is mined will produce a stone boulder. Loose stone and boulders are a byproduct of mining. These items are created by masons, mechanics, and stone crafters, each in their specific workshops.Įngraving and Stone smoothing, while not actual products or constructions, add value to your fortress, and can also be considered part of the Stone industry. The industry produces a variety of items under the following categories: 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 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. Your steel industry may be better served by requesting steel bars directly or by buying up everything they have that's made of steel, especially toys, instruments, and crafts, and melting it all down.Introduction to the Stone Industry Ī considerable industry centered on the use of stone is essential for any fortress. * If you are able to bring flux stone at embark, you will be able to request it from the caravan in meetings with the liaison (as with pretty much everything else), but they aren't likely to bring much, generally 3 or 4 stones of each type. Bituminous coal and lignite might be worth ordering while you're there. Make sure you order them from the 'Stone' section, since you can't use flux blocks to create steel. If your map has no flux on it (which is a common situation), then you can request it from the dwarven traders (assuming the traders have access to flux, which is not guaranteed*). Note that Borax, a real life flux, can not be used in the game. near volcanoes), unlike sedimentary layers. Marble is a metamorphic layer, so it can be found within almost any biome notably, marble can be found in the same biome as igneous extrusive layers (i.e. Limestone, dolomite and chalk form sedimentary layers, which can have large deposits of iron-bearing ore.

Whether or not a site has flux can be determined from the pre-embark screen. The following stones fall under this reaction class:Īll flux stones form layers (which are marked on the embark screen as 'Flux Layer(s)') except for calcite, which exists as small clusters within other flux layers. Note that blocks made out of flux materials cannot be used in the production of pig iron or steel. (Only obsidian and some higher-value ores have a higher material value for stonework.) All flux has a material value of 2, which is twice that of common stone (material value 1), making it preferable for workshops, construction, and almost all stone products. Stones which are classified as flux materials can be used in the creation of pig iron and steel at a smelter.
