Note that some content may still need to be updated.


The see-through kind.

Glass is produced at the glass furnace using fuel with either sand (green glass), sand and pearlash (clear glass), or rock crystal and pearlash (crystal glass). A magma glass furnace can also be used, in which case no fuel is required. Raw glass (of all three types) can also be acquired from some trade caravans and be purchased in the embark screen. Note that raw glass can not be made into glass items (excluding strange moods), but can only be cut into gem-like items which can be used for decorating items. You have to buy or collect sand to get the raw materials to make glass.

Glass value corresponds to the difficulty of its production, with green glass having the lowest material value (2), clear glass, intermediate (5), and crystal glass, the highest (10).

Uses[edit]

Glass can be used for most things that can be produced at a mason's workshop, with the exception of slabs, querns and millstones. Glass can also be used to make tubes. Note that the names for some glass products are different from the same products made from different materials. For example, a glass tube has the same uses as a wooden pipe. It can also be used to produce goods normally made at a craftsdwarf's workshop by a stone crafter, with the exception of obsidian short swords and generic crafts. In addition, it may be made as raw glass, which can then be cut as a gem at a jeweler's workshop by a gem cutter, in a similar fashion to cutting generic stones.

Raw glass, especially raw green glass, is excellent practice for aspiring jewelers (and its production provides experience for glassmakers). The value of glass is on par with low-to-mid value gemstones, meaning that a source of sand on your map used in tandem with a magma glass furnace makes decoration with cut raw green glass an essentially free, and very lucrative, way to increase the value of your goods, while training legendary glassmakers and jewelers – particularly when those goods are themselves made of glass.

Glass can also be made into blocks which can be used to build workshops and constructions, even glass trap components. Unique goods made from glass include glass windows and vials, as well as renamed versions of common furniture.

  • A glass chest is called a box.
  • A glass door is called a portal.
  • A glass pipe is called a tube.
  • A glass cage is called a terrarium.
  • A glass flask is called a vial.

For more information on the use of glass, see the Glass industry page.

Raw and cut glass storage options can be found under the Gem stockpile sub-menu. Glass blocks are stored in Bar/Block stockpiles.

Glass Block Floors, AKA The Dwarven X-Ray[edit]

In DF Premium's graphical mode, floors made out of glass blocks reveal the z-level directly beneath them and everything on those tiles in real time, even if built on top of a solid cave floor. This exploit can be a useful when you need to avoid digging into some Hidden Fun Stuff, because even though players can see through glass floors no matter what, entities in the game itself never can.[1]

Glass and magma[edit]

Glass behaves somewhat oddly with magma, despite being strictly magma-safe (with a melting point of 13600 °U ) - built glass furniture will survive indefinitely when covered with magma, but unbuilt glass items tend to disappear instantly when submerged in magma.Bug:10314

Physical properties[edit]

Through memory hacking, the material properties of each type of glass have been determined; for reference, they have been reconstructed below as material definitions:
