Glass

Glass is a refined construction material produced from Sand in a Glass Forge. The forge converts 100 kg of Sand into 25 kg of Molten Glass, and the molten product can then be cooled into solid Glass for use in construction. Because Sand melts at 1712.85 °C, it is typically converted with extreme heat sources or by using a Metal Refinery setup capable of creating the required temperatures. In addition to industrial production, Glass can also be recovered from renewable space points of interest in Space Debris, where it appears in varying amounts during rocket missions.

As a material, Glass is valued for its transparency and its role in several late-game and utility buildings. It is required to build the Solar Panel, Monument Top, Sun Lamp, and Pixel Pack. It is also one of the material options for the Window Tile and Aero Pot, making it useful anywhere visibility, decor, or a transparent building material is desired.

  • Monument Top
  • Sun Lamp
  • Pixel Pack
• Glass can be used as a material option for:
  • Window Tile
  • Aero Pot

Glass is especially important in space infrastructure, since Solar Panels and Monument Top both consume large amounts of it. Because of that, many colonies treat Sand management as a separate production chain rather than a low-priority mineral use. If a colony has access to magma or other very high-temperature environments, tiny amounts of Sand can also be introduced into a Metal Volcano’s molten output to produce Glass indirectly, though this is more of an advanced setup than a standard manufacturing route.

In practical use, Glass tends to be most efficient when reserved for buildings that specifically benefit from its transparent character or from its high-value late-game role. Window Tile and Aero Pot are common non-utility uses, while Sun Lamp and Pixel Pack make it part of aesthetic or illumination-focused projects. Since Glass production starts from Sand, securing a reliable Sand supply is the main long-term consideration for any colony that depends on it.
