Glass is one of those crafting materials in Pokémon Pokopia that the game expects you to figure out on your own. No tutorial points you toward it, and yet you need it for specific crafting recipes and Pokémon Center rebuilds. Once you know where to look and what to toss into the furnace, producing Glass becomes a reliable part of your resource loop.
How Do You Make Glass in Pokémon Pokopia?
To make Glass in Pokémon Pokopia, you need to smelt one of three raw materials inside a Smelting Furnace:
- Sand
- Volcanic Ash
- Sandstone
All three produce Glass when burned, so whichever material you have the most of works fine. That said, Volcanic Ash is by far the most practical option once you reach the right area of the map.

Where Is the First Smelting Furnace?
The first Smelting Furnace you can access sits inside a cave in Rocky Ridges, which you discover during the main quest. This is also where Magmar lives, and that detail matters a lot: Magmar fuels the furnace automatically, so you do not need to worry about finding a separate fire source when you are smelting here.
If you do not have Magmar available, any Pokémon with the Burn ability can follow you to the furnace and handle the smelting instead.

What Are the Best Materials to Use for Glass?
Here is a quick breakdown of each valid input material and how practical each one is:
| Material | Where to Find It | Abundance | Notes |
|---|---|---|---|
| Volcanic Ash | Rocky Ridges (everywhere) | High | Best early-game option |
| Sand | Various locations | Moderate | Useful if Ash runs low |
| Sandstone | Rocky areas | Moderate | Works but less common than Ash |
Volcanic Ash wins for early-game Glass production simply because Rocky Ridges is covered in it. You can gather a large stack quickly and smelt it all in one session.
How Do You Get Your Own Smelting Furnace?
You are not locked to the Rocky Ridges furnace forever. Magmar will eventually give you the crafting recipe for your own Smelting Furnace, which means you can build one wherever you set up your base. This opens up Glass production anywhere on the map without needing to trek back to Rocky Ridges every time.

What Is Glass Used For in Pokémon Pokopia?
Glass serves two main purposes in Pokémon Pokopia:
- Crafting recipes at your crafting bench that require Glass as an ingredient
- Pokémon Center rebuilds, where certain structures specifically call for Glass to complete the reconstruction
If you are working through rebuild quests, stockpiling Glass early saves a lot of backtracking later. It is worth running a few smelting sessions in Rocky Ridges as soon as you unlock the furnace.
Glass Crafting Steps
Here is the full process from start to finish:
- Progress through the main quest until you reach Rocky Ridges
- Locate the cave containing the Smelting Furnace (Magmar's location)
- Collect Volcanic Ash from around Rocky Ridges
- Place Volcanic Ash (or Sand or Sandstone) into the Smelting Furnace
- Let Magmar or a Pokémon with the Burn ability ignite the furnace
- Wait for smelting to finish, or use time travel to speed it up
- Collect your Glass and head to the crafting bench
Once Magmar hands over the Smelting Furnace recipe, you can build your own and skip the Rocky Ridges trip entirely for future batches.
