Where to find Quartz and Glass materials in Subnautica 2

Quartz and Glass are strong search targets because players hit them when they start caring about better tools, base pieces, and cleaner early progression.

Resources Long-tail material search Supports tools and bases

Quartz advice is rechecked when early material density, Glass recipes, or scanner/base requirements change.

Quick answer

The best early Quartz route is the one that keeps collection safe and repeatable. Players should gather enough to unlock the next practical base and tool upgrades instead of treating Quartz as a background material.

Page media

Use scanner timing before you overfarm Quartz or Glass.

Quartz pages are strongest when the next unlock path is checked against scanner, base, or tool value instead of becoming a blind stockpile loop.

Visual read

Farm Quartz only when the route has a real craft target

Quartz feels easy to over-collect. These reference shots frame it as a short, safe material loop that should lead directly into Glass, scanner support, or a named base/tool upgrade.

Use safe edges first.

Quartz is best gathered on routes you can repeat without breaking oxygen, food, or landmark discipline.

Convert only for a known unlock.

Keep raw Quartz flexible unless Glass immediately improves a tool, scanner path, or base function.

Quartz and Glass use table

Quartz is most useful when it supports a specific upgrade path. Use this table before converting everything into Glass.

Glass is a commitment. Keep Quartz raw unless a tool, scanner, or base recipe will use the Glass immediately.

Gather Quartz when Glass unlocks a real tool, base, or scanner benefit. Otherwise, avoid filling storage with unclear materials.
Need Use Quartz / Glass for Good timing Delay if
Tool progress Recipes that unlock safer scanning or gathering. The tool improves the next known route. The tool is for a route you cannot repeat yet.
Base utility Functional pieces that support storage or scanner flow. The first base location is worth keeping. Power and storage are still unstable.
Scanner support Upgrades or pieces that reduce repeated material hunts. One missing material blocks several crafts. You do not have one clear scan target.
Stockpile Raw Quartz reserve for competing recipes. You are unsure which unlock comes next. Glass is needed for an immediate survival upgrade.

Quartz gathering loop

  1. Start with the safest visible deposits near routes you already understand. Quartz is useful, but not worth breaking your oxygen or landmark chain.
  2. Gather in small batches and return before turning the trip into a general resource hunt. Quartz runs work best when they have one craft goal.
  3. Pair Quartz with Copper or Titanium only if both are on the same safe loop. Do not force a longer route just to combine errands.
  4. Craft Glass when it unlocks a specific upgrade, base piece, or tool path. Avoid converting all Quartz before you know the next recipe need.

Small-batch example: when to stop a Quartz run

A useful Quartz run should end with a decision, not with a locker full of "probably useful later" materials. Treat the first batch as a test: can it finish the next craft, point to Glass, or prove that another blocker matters more?

Batch result Best decision Why this avoids wasted farming
You gathered enough Quartz for the planned Glass craft. Return, convert only what the recipe needs, and use the craft immediately. The run turns into visible progress instead of storage clutter.
You found Quartz but the craft also needs another material. Stop Quartz farming and open the material page for the new blocker. The next route follows the real bottleneck instead of the easiest pickup.
The route gave Quartz but felt unsafe or confusing. Keep the batch small and improve landmarks, oxygen margin, or scanner support first. A repeated safe route is more valuable than one lucky larger haul.

How much Quartz or Glass should you gather first?

The safest early answer is "only enough to finish the next visible blocker." Quartz is easy to overfarm because it feels like a universal material, but a full locker does not help if the real blocker is Copper, storage, power, or a missing scan.

Current blocker Route goal Stop condition
One Glass-based craft is waiting Gather a small Quartz batch, return, and convert only the recipe amount. The craft is finished or another material becomes the named blocker.
Several recipes might need Quartz later Keep Quartz raw until one upgrade clearly improves survival, scanning, or base flow. You cannot name the craft that will use the next piece.
The route is safe but slow Repeat the same short loop once before widening into unknown terrain. The return path starts feeling uncertain or oxygen margins get thin.
Co-op players keep grabbing different materials Assign one player to Quartz and one to the other craft blocker. The next shared craft has enough material in one visible locker.

When Glass is worth it

  • Craft it when a survival, scanning, or base upgrade is waiting on it.
  • Delay it if oxygen, food, water, or storage is still the real bottleneck.
  • Keep some raw Quartz if multiple recipes are competing for the same supply.
  • Use Scanner Room support later if manual Quartz runs become too slow.

Open a Quartz route when

  • The next base, scanner, or tool upgrade is actually waiting on Quartz or Glass.
  • The route can be folded into a safe loop instead of a dedicated dangerous trip.
  • You already know whether the route is for raw Quartz or for immediate Glass crafting.

After a Quartz run

  1. Decide immediately whether the batch becomes Glass or stays flexible as raw Quartz.
  2. Spend it on the upgrade that improves the next route, not on scattered low-impact uses.
  3. Stop farming more if the next real blocker is now Copper, power, or scanner coverage.

First Quartz route plan

Route phase Do this Stop rule
First pass Follow a safe edge route and mark the return landmark before collecting. Leave after enough Quartz for the next Glass recipe or when the landmark feels weak.
Repeat loop Run the same path again and widen only one branch at a time. Stop when the next blocker becomes Copper, Titanium, scans, or base power.
Glass craft Craft Glass only for the recipe you can use immediately. Do not convert all Quartz if future recipes may need raw material.

Quartz batch audit

After banking the first batch, decide whether Quartz is still the blocker. This keeps the page useful for players who are gathering correctly but spending too late or converting too soon.

After banking If true Next move Stop farming if
A Glass recipe is ready now Quartz should become progress immediately. Convert only the amount the recipe needs. The recipe does not improve the next route.
Several recipes compete for Quartz Raw Quartz is more flexible than Glass. Hold the batch until one craft matters most. Storage is filling with no named upgrade.
The safe route felt too slow The route may need scanner support, not more swimming. Open Scanner Room planning before widening the path. Oxygen or landmarks already feel weak.
The next blocker changed Quartz did its job for now. Switch to Copper, power, storage, or scans. You are farming Quartz just because it is visible.

Quartz and Glass route ladder

Quartz is easy to overfarm because it feels useful everywhere. Use this ladder to decide whether the next trip should gather, convert, or stop.

Current state Best action Why Switch pages when
No clear Glass craft yet Gather only a small Quartz reserve on a safe route. The material is useful, but not worth stealing the whole run. You need to name the next craft first.
Scanner, base, or tool step needs Glass Run one focused Quartz loop and convert only enough for that step. Focused conversion keeps the route tied to progress. The blocker becomes base timing or scanner value.
Quartz route is safe and repeatable Bank a reserve, then stop and spend it. Extra stockpiles do not help if the next unlock is unclear. Another material now blocks the craft harder.

Glass conversion stop rule

Convert Quartz into Glass only when the craft is ready to use the result. If the Glass would sit in storage, the better next step is usually route planning, scanner timing, or base order.

  1. Name the exact craft before converting the batch.
  2. Convert the smallest amount that completes the current step.
  3. Use the finished craft, then decide whether Quartz is still the blocker.
