40d:Glass

Glass is an interesting material with widespread uses. Glass is manufactured in a Glass furnace or Magma glass furnace. There are three types of glass: Green, Clear and Crystal.

Green glass is manufactured from sand. Clear glass uses both sand and pearlash, while crystal glass is manufactured from Rock crystals and pearlash.

Sand can be gathered in bags using a task available at a glass furnace. You must designate a sand-gathering zone in order for this task to succeed.

Products

Glass can be manufactured into a wide variety of products:

• Raw glass is essentially a low-value gem, a frequent request of dwarves undergoing a strange mood. Given its abundance, raw green glass makes an excellent training material for practicing the gem cutting skill.
• Glass can be formed into blocks which can then be used for most building purposes. Although this is much more labor-intensive than simple using raw or block stone, some people feel that it has an aesthetic appeal; for example, see Leerok the Lacerta's Glass tower
• Glass can be used to manufacture a number of furniture items, including armor stands, boxes, floodgates, hatch covers, grates, portals, statues, tables, thrones and weapon racks.
• In addition, Glass can be converted into Trap components, such as large, spiked balls or giant axes. Unlike their metal counterparts, glass trap mechanisms each utilize only single units of their component materials. For example, a giant green glass axe blade requires only a bag of sand in order to manufacture. Since sand, if present on the map, if effectively an infinite resource, this is a very cheap way to fully outfit a fortress with weapon traps.
• Glass windows can be made at a glass furnace as an alternative to making windows from gems.
• Outside of Metal and Wood, Glass is the only readily available material for Cage construction. A glass cage is called a terrarium, and is unique among cages in that it may be converted into an aquarium using the an option in the building tasks/prefs menuqw. Terraria may not be used for justice applications.
• Glass vials are used in some types of plant processing, and are required to build an Alchemist's laboratory
• Glass can be formed into a variety of crafts.

Glass items often have unique names:

• 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.

Properties

Green glass has a material value of 2. Clear glass has a material value of 5. Crystal glass has a material value of 10.

The damage value of green glass is 50% (confirmed at Gem#Glass).
