Beach Sand
Fine-grained silica sand gathered from the tideline and dune areas of Bleak Beach, Beach Sand is one of the most abundant materials on the island and the raw input for Glass production. At high enough temperatures in a properly equipped furnace, Beach Sand fuses into the clear, smooth sheets that Pokopia's mid-game construction uses for windows, lamp globes, and reflective surfaces. It also appears directly in Sandbags and certain sun-baked outdoor items with a genuinely sandy texture.
Beach Sand is available in effectively unlimited quantities along the Bleak Beach waterline — the tide continuously replenishes the supply — but collecting it in bulk requires multiple trips, since carrying capacity limits how much can be transported per visit. Players who want to maintain a steady Glass production pipeline will find Beach Sand the easiest part of that supply chain to secure, making the processing infrastructure the real investment rather than the raw material.
