40d:Glass industry

In order to produce glass, your map must have sand (or rock crystal, for high-value crystal glass - see below). Sand is never carried by a caravan nor offered by a liaison. This is a dealbreaker (although there are some easy cheats to work around it.) If you want a glass industry, check on your pre-embark map for sand layers.

To produce glass, sand must first be gathered in bags using a task available at any glass furnace, "Gather Sand". You must designate a Sand Collection zone from the (i)-menu that includes an accessible area of sand 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, and probably many of them, perhaps a half dozen or more per active furnace. It's also a good idea to build spare furnaces just to have "Gather Sand" orders on Repeat, perhaps 2-3/active furnace, depending on your haulers and the distance. These furnaces don't use fuel and are not manned (dwarfed?) for the Gather Sand task, so if you are using magma Glass Furnaces, these can be standard versions, and in an out-of-the-way corner of the map - the sand haulers will never go there, but the orders have to come from there.*

(* You can also order "Gather Sand" through your manager, but some will get apportioned to the active furnaces, interfering with the actual manufacture of glass items. It's better to do this one manually, workshop by workshop.)

Once you have one bag of sand you can order glass to be created at the furnace. A standard glass furnace will consume one unit of fuel per job; a magma glass furnace uses no fuel.
