How to make clear glass windows?

Question

I can't make any windows from clear glass. Here are my steps:

• build glass furnace
• stockpile raw clear glass in my gem stockpile.
• make coke bars for fuel
• have lvl 16 glassmaker migrant with no other job enabled except glassmaking

On the glass furnace:

• a: Add new task -> clear glass (c) -> Make clear glass Window (i)

But the glassmaker does nothing, no one mounts the glass furnace, and the job eventually disappears from the glass furnace queue by itself. I try b -> y to build a window, but it says Needs window.

Answer 1

The glass furnace will need three things to make a clear glass window:

• Sand bag
• Pearlash
• Fuel

Once you have all three of these things available, order your glass furnace to craft the clear glass window. Once the clear glass window is crafted it will be carried by a dwarf to a furniture stockpile, at which point you can build it.

You will not be able to use raw clear glass for anything except for cutting it at a jeweler's workshop or building with it.
