40d:Glass

Glass is a translucent material with widespread uses. Glass is manufactured at a glass furnace or magma glass furnace. There are three types of glass: Green, Clear and Crystal, each with different colour and value.

Green glass can be considered renewable (how so?) if produced at a magma furnace, making it a valuable resource for construction. Green glass goods are manufactured from one bag of any sand.

Clear glass uses both a bag of sand and one pearlash.

Crystal glass is manufactured from one rough rock crystal and one pearlash.

In order to produce glass, sand must be gathered in bags using a task available at a glass furnace. You must designate a sand-gathering zone from the (i)-menu in order for this task to succeed. Gathering sand requires item hauling whilst moving sand bags to stockpiles requires furniture hauling. You will need spare bags in order to collect sand.

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.
• 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.
• Glass can be converted into trap components, such as spiked balls or giant axe blades.
• Glass windows can be made at a glass furnace as an alternative to making windows from gems.
• Cages may be made from glass. 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, making extracts, and three clear glass vials 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.
