If you’ve ever tried to build a sleek observation tower, craft a high-tier scanner upgrade, or fulfill a settlement construction request in No Man's Sky, you’ve probably hit a wall when you realize you don’t know how to get glass in No Man's Sky. It’s one of those mid-game materials that feels impossible to track down at first, but once you have a consistent system set up, you’ll never run out again. I’ve spent dozens of hours testing different farming routes and crafting methods across three separate playthroughs, so I’m breaking down every reliable way to get it, plus small hacks to cut your farming time in half.
How to Get Glass in No Man's Sky via Core Crafting
The most consistent and cost-effective way to get glass is to craft it yourself using a medium or large refiner. You can’t make glass in a portable refiner, so make sure you have access to a larger refining unit either at your base or on your freighter before you start gathering materials. The current standard recipe for a single piece of glass is 50 frost crystals plus 40 dioxite, and the refining process takes roughly 30 seconds per piece.
Frost crystals only spawn on cold, frozen biomes, so you’ll need to scan for planets with freezing temperatures when you jump into a new system. They grow in bright blue, spiky clusters on the surface, often near rock formations or frozen bodies of water. Always bring a level 2 or higher cold hazard protection upgrade before you land on a frozen planet, as unprotected exposure can drain your life support in 10 seconds or less during extreme cold storms.
Dioxite is a little easier to find, spawning on frozen, barren, and even some toxic planets, usually in cave systems or near large rocky outcrops. If you don’t feel like hunting for dioxite specifically, you can also get dioxite as a byproduct of refining copper and ferrite dust together, which is perfect if you already have large stockpiles of those common materials from earlier exploration.
Reliable Glass Farming Routes for Consistent Supply
If you only need one or two pieces of glass for a quick upgrade, you can just gather the required materials on a single trip to a frozen planet and craft them on site. But if you plan to do a lot of base building or craft high-tier upgrades regularly, setting up a permanent glass farm will save you hours of travel time over the course of your playthrough.
The best farms are set up on a frozen planet that has both frost crystals and dioxite spawning naturally, so you don’t have to jump between systems to gather materials. When you find a suitable planet, look for a spot with a large, dense cluster of frost crystals, then build a small outpost right next to it. You don’t need anything fancy for your farm, just these core components:
- 4-6 hydroponic trays planted with frostwort to generate infinite frost crystals
- 1 medium or large refiner placed within 10 feet of your harvest point for on-site crafting
- A medium storage container to stockpile excess dioxite and pre-crafted glass
- A base teleporter so you can jump back to your farm any time from anywhere in the galaxy
Planting frostwort in your base hydroponics trays is the most low-effort way to get infinite frost crystals – each frostwort plant gives 25 frost crystals when fully grown, and they only take 30 minutes to mature even if you’re off exploring other planets. You can also find glass in random loot crates at trading posts, abandoned buildings, or sentinel outposts, but those drops are totally random and not reliable for large supply needs. Some NPC traders at space stations sell glass too, but it usually costs 30,000+ units per piece, which is way more expensive than crafting it yourself.
Common Mistakes to Avoid When Farming Glass
I made a lot of silly mistakes when I first started farming glass, so I’m saving you the frustration by calling out the most common ones first. The first mistake is trying to craft glass in a portable refiner. I once hauled 200 frost crystals and 160 dioxite to a frozen planet thinking I could craft 4 pieces of glass on the spot, only to realize the portable refiner doesn’t support the glass recipe. I had to call my freighter in just to access a medium refiner, which wasted 20 minutes of play time.
Another common mistake is forgetting to upgrade your multi-tool’s mining beam before you go farming. Frost crystals and dioxite both take longer to mine than common materials like ferrite dust, so a mining beam upgrade with increased damage and resource yield will cut your gathering time in half. You should also install a resource scanner upgrade on your exosuit to highlight frost crystal and dioxite deposits from farther away, so you don’t waste time wandering around the planet looking for spawns.
Don’t make the mistake of only making one or two pieces of glass at a time. If you’re building a large base or working on a full set of high-tier upgrades, you’ll easily need 20+ pieces of glass total. Craft as much as you can in one go when you’re at your farm, then store the excess in your base storage so you don’t have to keep making trips back every time you need one more piece. And unless you’re in a real emergency, skip buying glass from traders – that units are better spent on inventory upgrades or faster starship engines.
Creative Uses for Glass in Your No Man's Sky Playthrough
A lot of new players only think of glass as a base building material, but it has a ton of useful applications across every part of the game. For base builders, glass panels let you build sleek, modern bases with floor-to-ceiling windows to watch alien sunsets, transparent greenhouse walls for your hydroponic farms, or even full glass observation domes on top of mountain bases. I built a glass skywalk on my main base that stretches 200 feet out over a canyon, and it’s still my favorite spot to stop and take screenshots.
Glass is also a key component for a lot of high-tier upgrades, including multi-tool scanning enhancements, starship shield boosters, and exosuit hazard protection modules. If you want to explore extreme biomes or take on high-level sentinel fights, you’ll need a steady supply of glass to craft and upgrade those modules. Glass is also required to complete several main story missions and random settlement construction requests, so keeping a stack of 10-15 pieces in your inventory at all times will save you a lot of hassle when you get a random request mid-exploration.
If you have extra glass from your farm, you can also use it for trade. Most construction-focused NPCs will pay 20,000 to 25,000 units per piece of glass, which adds up fast if you have a large farm producing 20+ pieces every half hour. I once sold 50 pieces of excess glass to a trader at a space station and made enough units to buy a whole new S-class hauler, so don’t sleep on glass as a passive income source.
At the end of the day, figuring out how to get glass in No Man's Sky doesn’t have to be a frustrating chore. Once you set up that simple hydroponic farm on a cold world, you’ll have a steady supply for all your building, crafting, and trading needs. I still have my first glass farm set up on a tiny frozen moon 300 light years from my main base, and I jump back every couple of days to harvest and restock. Don’t skip the small upgrades like cold resistance and a better mining beam, those little touches will make the whole process way smoother.
