Where to Find Quartz in Subnautica 2
Complete guide to finding Quartz in Subnautica 2 — best biomes, locations, and how to farm this essential glass-making resource efficiently.
Quartz is the primary material for glass production in Subnautica 2. You need it for windows, observatories, and the Habitat Builder itself. With 312 known deposits, it is abundant but requires knowing where to search.
Why You Need Quartz
- Glass — Requires 2 Quartz. Glass is used in windows, observatories, and the Habitat Builder
- Habitat Builder — The essential base-building tool requires Glass
- Flashlight — Requires Quartz for the lens
- Reinforced windows — Base viewing ports and large observation windows
- Scanner — Requires Quartz for optics
Without Quartz, you cannot build glass — and without glass, you cannot expand your base or craft essential tools.
Best Biomes for Quartz
Quartz appears as translucent white crystalline nodes, often in clusters:
- Shallow seabeds — Quartz is visible on the seafloor in the starting area, especially on sandy patches
- Cave entrances — Quartz clusters often form near cave mouths where light reaches
- Rocky ridges — Crystal formations along the tops of rock formations
- Welcome Center area — Dense clusters around the structure’s foundation
- Grassy plateaus — Open areas with scattered quartz deposits
How to Identify Quartz
Quartz deposits are white or light-pink crystalline formations that protrude from the seafloor. They reflect light, making them relatively easy to spot during daytime exploration. Unlike metallic ores, Quartz has a distinctive crystalline appearance.
Quartz vs. Other Crystal Resources
| Resource | Appearance | Primary Use |
|---|---|---|
| Quartz | White/pink crystals | Glass, optics |
| Celestine | Blue crystals | Decorative, some recipes |
| Salt | White granular deposits | Food preservation, acid |

Efficient Quartz Farming Route
- Start at the Lifepod and scan the sandy seafloor in all directions
- Quartz is highly visible against sand — collect every node you spot
- Head toward the Welcome Center — dense clusters around the perimeter
- Check the tops of rock formations between biomes
- Return through the shallow reef areas
Expected yield: 15-25 Quartz per 10-minute collection run.
FAQ
Where is Quartz found in Subnautica 2?
Quartz is found on sandy seafloors, near cave entrances, and around rock formations in the starting area. It appears as white crystalline nodes.
What is Quartz used for in Subnautica 2?
Quartz is smelted into Glass (2 Quartz per Glass). Glass is used for windows, observatories, the Habitat Builder, Flashlight, and Scanner.
How to get Quartz fast in Subnautica 2?
Quartz is most visible against sand. Focus on open sandy areas near the Lifepod and Welcome Center. A 10-minute sweep yields 15-25 Quartz.
Can you craft Glass without Quartz?
No, Glass requires 2 Quartz in the Fabricator. There is no alternative recipe.
