Glassmaking is real in Build 42, but small: about ten recipes. It matters because it is the only way to make new jars and bottles once the shelves are empty. It sits on top of pottery, so start there. Updated for Build 42.21 Stable and 42.22 Pre-Release, November 2026.
Everything starts with a small ceramic crucible full of molten glass:
One guide says melting happens at the smelting furnace, the second blacksmithing furnace tier. One crucible reportedly makes 4 items (one source).
The glass blowing pipe is sculpted at Pottery 2 and fired in a kiln. The small crucible is a pottery item too. Blowing bottles, jars and glasses needs pliers, the blowing pipe and a crucible of molten glass; the pliers and pipe are kept. A glass pane is cast in a ceramic sheet mold, which is also kept.
| Item | Glassmaking | Base XP | Magazine |
|---|---|---|---|
| Glass pane | - | 25 | Carlow Crystal Guide |
| Drinking glass | 2 | 45 | Carlow Crystal Guide |
| Glass bottle | 3 | 60 | Bottle Making at Home |
| Glass jar | 5 | 75 | Bottle Making at Home |
| Wine glass, lantern glass | 7 (one table) | 90 | Murano Glass Manual |
| Champagne glass | 9 (one table) | 90 |
The mirror is also on the list. Level requirements above level 5 differ between PinDrop's two tables, so check the crafting menu. Jars are what you want for canning.
Usual curve, 32,775 XP to level 10. Books run from "Glass: A History" (I) to "Venetian Glass: An Electron Microprobe Analysis" (V), x3 to x16. The Artisan trait gives +1 Glassmaking and +1 Pottery; no occupation boosts it. Most recipes are magazine-only, so hunt for the three glass magazines before you invest.
Opinion Glassmaking is a late-game hobby. Do it when you run out of jars, not before.
| Item | Base XP |
|---|---|
| Champagne glass, lantern glass, wine glass | 90 each |
| Glass jar | 75 |
| Glass bottle | 60 |
| Mirror | 50 |
| Drinking glass | 45 |
| Glass pane | 25 |
The Artisan trait starts you at Glassmaking 1, which avoids the ×0.25 penalty at level 0. (One source: pindrop.gg.)
Conflict: pindrop.gg gives two lists. Learned from a magazine, TV or job, recipes open earlier; learned only by levelling, one level later or more.
| Recipe | With magazine/TV | By level alone |
|---|---|---|
| Drinking glass | 2 | 4 |
| Glass bottle | 3 | 5 |
| Mirror | 4 | 5 |
| Glass jar | 5 | 6 |
| Lantern glass | 7 | 8 |
| Wine glass | 7 | 8 |
| Champagne glass | 9 | 10 |
Every skill uses the same XP ladder in Build 42 (one source: pindrop.gg skill guides).
| Level | XP for this level | Running total |
|---|---|---|
| 1 | 75 | 75 |
| 2 | 150 | 225 |
| 3 | 300 | 525 |
| 4 | 750 | 1,275 |
| 5 | 1,500 | 2,775 |
| 6 | 3,000 | 5,775 |
| 7 | 4,500 | 10,275 |
| 8 | 6,000 | 16,275 |
| 9 | 7,500 | 23,775 |
| 10 | 9,000 | 32,775 |
Starting level changes how fast you learn: ×0.25 at level 0, ×1 at +1, ×1.33 at +2 and ×1.66 at +3 or more. Fast Learner multiplies by 1.3, Slow Learner by 0.7. Skill books stack on top of this.
We did the sums so you do not have to. Going from level 1 to level 5 takes 2,700 XP. With no book read, that is 36 glass jars or 108 panes. Jars give three times the XP of a pane, but they need level 5 or 6 to make, so panes and drinking glasses carry you through the early levels.
Read the volume for your level before you light the furnace. Volume I triples your XP at levels 1 and 2, so the 150 XP from level 1 to level 2 costs 2 panes instead of 6. Start with the Artisan trait if you can: at level 0 every piece of glass is worth a quarter, and the first level alone would cost 12 panes.
Yes, in Build 42, but it is a small skill with about ten recipes.
You can cast glass panes in a ceramic sheet mold after reading the Carlow Crystal Guide.
Yes. The glass jar needs Glassmaking 5 and the Bottle Making at Home magazine.
Sacks of sand or broken glass, charcoal, a small ceramic crucible, tongs, pliers and a glass blowing pipe.
Most are taught by magazines. Read the glass magazines first.
