Six refining passes from Sand
Fully Refined Sand is the result of six successive Refiner recipes after ordinary Sand. Each refining pass uses 2 of the previous grade to produce 1 of the next in 3 seconds at the base recipe speed.
Prepare and refine the Sand
- Start with a Grinder: 1 Stone becomes 1 Sand in 12 seconds.
- Feed 2 Sand into the first Refiner to make 1 Refined Sand in 3 seconds.
- Pass the Refined Sand through the next four grades in order. Every pass consumes 2 of its previous grade and produces 1 of the next grade in 3 seconds; these intermediate items share the displayed name Refined Sand.
- At the final sand-refining stage, combine 2 of the preceding Refined Sand grade to produce 1 Fully Refined Sand in 3 seconds.
Continue from sand to gems
- Use a Refiner to turn 2 Fully Refined Sand into 1 Crude Shard in 3 seconds.
- Use a Refiner to turn 2 Crude Shard into 1 Broken Shard in 3 seconds.
- Use a Refiner to turn 2 Broken Shard into 1 Dull Shard in 3 seconds.
- Use a Refiner to turn 2 Dull Shard into 1 Shattered Crystal in 3 seconds.
- Use a Refiner to turn 2 Shattered Crystal into 1 Crude Crystal in 3 seconds.
- Use a Refiner to turn 2 Crude Crystal into 1 Polished Crystal in 3 seconds.
- Use a Refiner to turn 2 Polished Crystal into 1 Adamant in 3 seconds.
- Use a Refiner to turn 2 Adamant into 1 Diamond in 3 seconds.
- Use a Refiner to turn 2 Diamond into 1 Perfect Diamond in 3 seconds.
Balance the refining line
- How should I connect and size each Refiner stage?
- A Refiner has two conveyor inputs and one conveyor output. Route its output into the next grade; each successive level needs half as many Refiners as the previous level because the material flow halves.
- How far beyond Fully Refined Sand is Diamond?
- Diamond is eight more refinement steps beyond Fully Refined Sand. It takes 16,384 original Sand to make one Diamond. Perfect Diamond adds another refinement after Diamond.
