Glass

A transparent, solid material useful for more than just windows.

Notes

Glass is a tier-3 building block and a versatile industrial ingredient. It is crafted from sand (and other materials) through the Glass or Quicklime Glass recipes, and its transparency makes it essential for windows, while also serving as a component in advanced items like Fiberglass, Glass Lenses, and Fuses. Because it is used in many mid-to-late-game recipes (including Country Foundation and the Ink required for high-tier research papers), establishing a steady glass supply early in this tech tier supports both construction and industrial progression.
