Conan Exiles Glass: Recipe, Crystal and All 13 Uses

Conan Exiles Glass comes out of the Furnace: 2 Crystal smelt into 1 Glass per cycle. According to community sources you don't need a separate unlock for it, because the recipe comes with the Furnace.

This guide covers the confirmed recipe, where the Crystal comes from, all 13 recipes in the Enhanced database that use Glass, and our own math: how much Crystal does it take to build every one of those recipes in Conan Exiles once?

🔥 The Conan Exiles Glass Recipe

The values come from the game data database conanexiles.th.gl, which reflects the current state of Conan Exiles Enhanced. There the item is called Glass, the ingredient Crystal and the station Furnace.

PlayStation Universe and Conan Fanatics both confirm the 2 to 1 ratio independently. The Furnace needs fuel such as wood or coal. None of the sources we checked lists a craft time, and the database doesn't either. If you need it, read it straight off the recipe in the Furnace.

Conflicting claim: The GINX article (last updated July 2024) says Glass is made in the Charcoal Kiln. No other source backs that up, and the database only lists the Furnace. We consider the GINX claim an error.

Unlocking Glass Through the Furnace

According to the community wiki on Fandom, the Furnace is unlocked with the Blacksmith knowledge at level 10 for 2 knowledge points. Fextralife and PlayStation Universe both put its build cost at 540 Stone.

Conan Fanatics (January 2023, revised October 2023) says the Glass recipe is available in the Furnace without any extra knowledge. The database doesn't list a separate knowledge for it either. We weren't able to double-check this in the Enhanced client.

💎 Where the Crystal Comes From

Crystal is the only raw material for Conan Exiles Glass. Three sources are confirmed:

• Caves: For the Exiled Lands, Conan Fanatics lists Hanuman's Grotto, Warren of Degenerates, Cavern of Fiends, Scuttler's Shortcut and The Passage. GINX also names Hanuman's Grotto and Scuttler's Shortcut. Use a pickaxe rather than your bare hands.
• Crystal Rocknose: According to the Enhanced database, it drops Crystal on every harvest plus a 35 percent chance of extra Crystal, but it has only nine spawn points in the Exiled Lands. Every type is covered in our Rocknose farming guide.
• Vendor: conanexiles.th.gl lists the Traitor of Blood, who sells Crystal for 0.25 Blood.

On the Isle of Siptah, Crystal is rarer according to Conan Fanatics, with Vaults and Leyshrines as your best bet. We couldn't find a reliable source for how much Crystal a node gives per hit. Other materials and the right tools are in the resources guide.

🧪 What You Need Conan Exiles Glass For

For Conan Exiles Enhanced, conanexiles.th.gl lists 13 recipes that call for Glass directly. The amounts come from the individual recipe pages:

* We couldn't confirm the exact English name of the bench for these decor recipes, so check the recipe screen in-game before you build.

For The Glasser, Conan Fanatics also lists 1 Fragment of Power, which the database doesn't. According to Conan Fanatics you learn the recipe in the archive of the Unnamed City. More on that in our Unnamed City guide.

The Glass Flask: Station and Amount Disputed

This is where the sources split. The database lists 3 Glass at the Casting Table. Conan Fanatics confirms 3 Glass at the Casting Table and adds a reusable mold made from 15 Iron Bars. Older guides from 2017, on the other hand, describe the Furnace plus a mold. We go with the Casting Table and 3 Glass because that's what the game data database shows.

According to the database, the flask is the base for filled water flasks, Soul Essence and Sacrificial Blood. It also shows up in 31 dye recipes at the Dyer's Bench.

Unlocks for the Glass Recipes

The levels come from Conan Fanatics and the community wiki, not from Funcom. The Alchemist's Benches unlock at level 58 with Grandmaster Alchemist, the Wall Lantern at level 41 through the Torchbearer knowledge (3 points). According to Conan Fanatics, the Wine Basket, Wine Rack and Wine Shelf are part of the Debaucheries of Derketo DLC, and the Illusionist Mirror came with the Age of Sorcery Chapter 2 Battle Pass.

🧮 The Math: What All 13 Recipes Cost in Crystal

Our own math based on the database amounts: building each of the 13 recipes exactly once takes 353 Conan Exiles Glass, which means 706 Crystal. The two Alchemist's Benches account for the biggest share with 200 Glass combined, or 400 Crystal. The other eleven recipes add up to 153 Glass.

What the math shows: For flasks and the Compass, Crystal barely matters. Ten flasks cost 60 Crystal. It only gets expensive with the Alchemist's Benches. For comparison, a single Dragonpowder takes 50 Crystal directly in the recipe according to our Dragonpowder guide, as much as 25 Glass from the Furnace. If you're expanding explosives and alchemy at the same time, both pull from the same Crystal stockpile.

For the benches, Crystal isn't the bottleneck. The 200 Hardened Brick per bench need just as much Stone Consolidant and therefore Resin, as our Hardened Brick guide works out. According to the database, each Insulated Wood costs 2 Resin; where that comes from is in the Resin guide, and the Steel Reinforcement is covered in the Steel guide. All values assume default server settings.

💡 Tips for Producing Conan Exiles Glass

• Put the Crystal in the Furnace itself: According to Funcom's patch notes from May 5, 2026, auto-queue stations like the Furnace don't pull from nearby inventories. Ingredient and fuel have to sit in the Furnace. How the feature works for other stations is in our Craft from Storage guide.
• Don't tie up the Furnace with iron: If you're running Iron Bar production at the same time, set up a second Furnace just for Crystal.
• Plan your stock in pairs: Always load Crystal in even numbers, or a single Crystal stays behind in the Furnace. For one Alchemist's Bench that's exactly 200 Crystal.
• Flasks first, benches later: If you want to dye gear or fill water early, a few dozen Crystal will do. You only need the big stockpile for the alchemy stations from level 58.
• Caves over the surface: Every source places Crystal mainly in caves.
