Quick Answer

Crushed Bones

The normal way to get Crushed Bones is to process Bones in a Grinder. One batch takes 1 Bones and returns 1 Crushed Bones. If you already have the ore but cannot make a Crushed Bones, the missing piece is usually the Grinder itself or its setup, not another mining unlock.

Make Crushed Bones using the Grinder.

One batch turns 1 Bones into 1 Crushed Bones — enough for Crushed Bones to be worth smelting in bulk rather than one at a time. Neither a fuel cost nor a processing timer is recorded for this recipe.

Can I get Crushed Boneses yet?

The answer depends on where you are, not on the item itself.

If you have a Grinder

Yes. Get Bones and process it — the recipe runs with the ore alone.

If you have Bones but no Grinder

Not through processing yet. Unlock your first Grinder — the chain is below.

If the Workshop route is not open

The Grinder is tied to the Workshop progression, so that chain comes before the recipe.

If you are already in later areas

You may also find Crushed Boneses elsewhere — see the alternatives below.

What you need first

Each of these is stated once. Finish them in this order and the recipe will run.

How to make Crushed Bones

  1. Step 1 — Get 1 Bones

    Best early source: Pick up · Closet.

  2. Step 2 — Use the Grinder

    Place the Grinder, then load 1 Bones. No fuel is recorded for this conversion, so the ore is the only thing consumed.

  3. Step 3 — Collect the output

    Each batch yields 1 Crushed Bones. The game data records no processing timer, so it does not state how long a batch takes.

Bones vs Crushed Bones

These two are the most common mix-up in the early game, in whichever direction you are coming from.

BonesCrushed Bones
Raw material, mined or boughtProcessed material, made in a Grinder
Accepted by quests that ask for oreAccepted by crafting recipes that ask for bars
Cannot substitute for a Crushed Bones in a recipeCannot substitute for Bones in an ore hand-in

Why can’t I make Crushed Bones?

Not having the ore and not being able to process it are different problems. Pick the one that matches you.

What’s stopping you?

The earliest recorded source is Pick up · Closet. Mine the nodes on the earliest floor you can reach and smelt in bulk, since one batch returns 1 Crushed Bones.

What is Crushed Bones used for?

16 recorded recipes consume Crushed Bones. This is what makes it worth keeping rather than selling.

Quest-critical

Dense Fertilizer (Lv2)

The recorded recipe also takes Common Mushroom, Compost Bin. It takes smelted materials, never the raw ore, so Bones will not substitute here.

How many the quest needs is recorded in the quest guide rather than in the recipe data. Open the Dense Fertilizer (Lv2) guide →

Crafted stations and equipment

15 recorded recipes take Crushed Bones. Ingredient counts per recipe are not in the game data, so only the recipes are listed.

What else the Grinder makes

The Grinder handles more than one ore, so the same setup covers the other bars you will need.

Everything the Grinder converts
InputOutput
Bones ×1Crushed Bones ×1
Wheat ×1Dough ×1
Eyeball ×1Secret Sauce ×1

How many Crushed Boneses do you need?

Uses the recorded ratio, so the count is exact rather than a rule of thumb.

That is 8 batches, so bring 8 Boneses. Each batch returns 1 Crushed Bones, so 8 batches cover the 8 you need.

Keep them or sell them?

16 recipes take Crushed Bones, so it is an input for the next stage of crafting rather than something to sell off. The item database records a single price of 6 and does not store a separate sell value, so a resale figure would be a guess. Hold the bars until the recipes that need them are built.

FAQ

How much Bones does one Crushed Bones take?

One batch is recorded as 1 Bones in and 1 Crushed Bones out. There is no way to run a smaller batch, so the ratio is fixed.

Does Grinder need fuel?

No fuel cost is recorded for this recipe. The data records the input, the output and nothing else, so nothing is charged beyond the Bones.

Can I buy Crushed Boneses instead of making them?

No seller is recorded. The only reliable route is processing Bones.

Can Bones be used instead of Crushed Bones?

No. Recipes that ask for Crushed Boneses will not accept Bones, and quests that ask for Bones will not accept Crushed Bones. They are separate items.

Does one Bones give one Crushed Bones?

No — the recorded batch is 1 Bones to 1 Crushed Bones, so every Bones you smelt returns more than one bar. Mine a small stack and process it together.
