Editing 40d:Glass

{{quality|Exceptional|08:32, 11 April 2012 (UTC)}}{{av}}
[[Glass]] is a [[material]] that items can be made of, like [[stone]] or [[wood]].  But although a material, "glass" as such does not appear in a pre-processed form like other materials can, such as wood logs or mined stones - the game only knows finished products made of glass, and also "raw glass", which functions like an uncut [[gem]]. 

All glass items are manufactured at a [[glass furnace]] or [[magma glass furnace]] by a [[glassmaker]]. There are three sub-types of glass: '''Green''', '''Clear''' and '''Crystal''', each with different colour and value, but all with the same uses.

Green glass can be churned out in massive amounts if produced at a magma furnace, because there are no ingredients other than [[sand]] used and sand sources cannot be depleted. This makes it a valuable resource for construction; it is as valuable as any [[flux]] stone, but can create a [[glass industry#Glass Industry Flowchart|wider variety]] of final products, and some unique, such as [[gem]]s and [[aquarium]]s.  

==Making glass items==
The raw material components of glass (depending on the sub-type of glass item you are making) are [[sand]], [[pearlash]] and/or rough [[rock crystal]]s.  As neither sand nor rough rock crystals can be imported by [[caravan]]s, the ability to produce glass is determined solely by your embark region.

:*'''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 [[bar]] of [[pearlash]] - it uses no sand.  

In order to produce glass, sand must first be gathered in bags using the Collect Sand task at any glass furnace.  You must designate a sand-gathering zone from the ({{k|i}})-menu in order for this task to succeed.  Collecting sand requires [[item hauling]], whilst moving sand bags to stockpiles requires [[furniture hauling]].  You will need spare bags in order to collect sand. Note that although Collect Sand does not utilize the furnace itself, or the skills of a glassmaking dwarf, it will block any subsequent tasks at that furnace until it is finished. Therefore when entering mass production, it is more efficient to have extra glass furnaces strictly set to Collect Sand while the main furnaces run true glassmaking jobs - since collecting sand is generally slower than producing a glass item, a ratio of at least 3:1 is recommended.  The "Collect Sand" task consumes no [[fuel]], but is not possible to designate at an un-powered [[magma glass furnace]].

You can import [[bag]]s, but there is no way to [[trade]] for [[sand]], (filled) sand bags, raw glass or glass items.

==Products==
Glass can be manufactured into a wide variety of products:  

* Raw glass is handled by the game like a [[gem|rough (uncut) gem]]; thus, raw green glass makes an excellent training material for practicing the [[gem cutting]] skill, especially if you have [[magma]].
** Due to a bug, it is not possible to cut raw clear glass at a Jeweler's workshop without issuing a work order via your [[manager]].
* Raw glass is also a frequent request of dwarves undergoing a [[strange mood]] (if you have sand on your map).
* Glass can be formed into [[block]]s which can then be used for most building purposes.
* Glass can be used to manufacture a number of [[furniture]] items, including [[armor stand]]s, [[chest|boxes]], [[floodgate]]s, [[hatch cover]]s, [[grate]]s, [[door|portals]], [[statue]]s, [[table]]s, [[throne]]s and [[weapon rack]]s.
* Glass can be converted into [[trap]] components, such as [[spiked ball]]s or [[giant axe blade]]s.
* Glass windows can be made at a [[glass furnace]] as an alternative to making windows from gems.
* [[Cage]]s 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 an option in the building tasks/prefs menu{{key|q}}{{key|w}}.  Terraria may not be used for justice applications.
* Glass [[vial]]s are used in some types of plant processing, making extracts, and three clear glass vials are required to build an [[alchemist's laboratory]]. This makes the [[glass industry]] essential before a [[soap industry]] can be established.
* Glass can be formed into various [[toy]]s and [[instrument]]s (but not actual [[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.
* A glass [[flask]] is called a [[vial]].

==Material value==
* Green glass has a value of 2.
* Clear glass has a value of 5.
* Crystal glass has a value of 10.

The damage value of glass weapons is 50%, the same as that of [[silver]].
