First Gold loop · Sorting

Filter Wet Sand without trapping the loop.

Wet Sand is the first material that proves a factory needs both production and separation. It becomes Gold and Residue on a Shaker, but filters only work predictably when the feed is shallow and density is respected.

Working route

Use the constraint
as the design.

  1. 01 · Make Wet Sand

    Bring Sand and Water into contact. One Sand pixel plus one Water pixel becomes two Wet Sand pixels.

  2. 02 · Feed a Shaker

    Place Wet Sand on top. Each pixel becomes one Residue, with about a one-in-four chance to also produce Gold through the machine bottom.

  3. 03 · Route the two exits

    Collect Gold below the Shaker. Give Residue a clear side route; it remains on top and is pushed slowly in the Shaker's facing direction.

  4. 04 · Keep the filter feed shallow

    A Filter sends its configured material downward. In a tall mixed pile, lower-density pixels may be held above denser material and fail to reach it.

  5. 05 · Prioritise density

    For a Gold and Sand mix, allow Gold first because it is denser and settles lower. Do not depend on a Filter to untangle a deep, mixed stack.

How do I make Wet Sand in Sandustry?

Touch Sand and Water together. The official recipe is one Sand plus one Water becoming two Wet Sand pixels.

What does Wet Sand do in a Shaker?

Each Wet Sand becomes one Residue and has roughly a 25% chance to also produce one Gold. Gold exits through the Shaker bottom while Residue stays on top and moves slowly sideways.

Why is my Filter not pulling Wet Sand through?

A tall pile can prevent lower-density pixels from reaching the Filter through denser material. Reduce the pile height and filter dense material first.

Evidence notes

Confirmed first.
Tested second.

Official Wiki

  • Wet Sand has density 150 and is created from Sand plus Water; one Sand plus one Water becomes two Wet Sand.
  • A Shaker always converts Wet Sand into one Residue and has around a 25% chance to drop Gold through its bottom.
  • Filters can allow or block one pixel type, and the official Wiki recommends filtering the densest pixels first from a pile.
