Crystal Clear is a one-step side quest handed out by the Trademaster, and it looks simple until you open a Furnace and discover you cannot make a Lens yet. The whole quest hinges on a single missing piece of equipment, and everything else is just gathering materials to build it.
Quick answer: Research the Bellows blueprint under Metallurgy, build the Bellows extension next to Furnace I, smelt 3 Lenses from sand, then hand them to the Manager on the Main Pier.

The quest becomes available after Docked and Found. Its journal entry asks you to bring the optic glass to the Manager at the Main Pier, and the optic glass in question is the Lens item.

Open a Furnace before you go hunting for materials and the problem is immediately visible. The Lens recipe is listed at Smithy II, Furnace I and Furnace II, but it stays locked behind a “Required extension: Bellows” line. Without that extension bolted onto the furnace, no amount of sand will produce anything.
Unlock the Bellows blueprint in the Metallurgy tech tree
Open the Technology Tree and move to the Metallurgy branch. The node you want is labelled Blueprint: Bellows, and its description confirms it is an extension for Furnace I and Furnace II. Buying that single node does two jobs at once. It puts the Bellows into your build menu and it unlocks the Lens recipe itself, so there is no separate research to chase afterwards.
Materials for the Bellows extension and the Lenses
Two shopping lists matter here. One builds the Bellows, the other feeds the furnace once the Bellows is standing.
| Item | Amount | Where it comes from |
|---|---|---|
| Leather Scroll | 2 | Writing Desk, Writing Basement |
| Wooden Plank | 4 | Workyard timber processing |
| Bronze Nails | 4 | Workyard metal production |
| Sand | 5 per Lens | Sand pit by the river |
Where to dig up Sand
Sand comes from an excavation node on the riverbank, west of the garden and north of the forest, in the stretch of woodland near the Inquisition Base. Interact with the pit repeatedly to fill your bag. Each Lens costs 5x Sand, so budget at least 15 for the three the Trademaster wants, and collect a little extra if you plan to keep making glass later.
How to craft Leather Scrolls
Leather Scrolls are the awkward ingredient because they start in the Morgue. Skin is harvested from corpses on the autopsy table, then carried down to the Writing Desk in the Writing Basement, where it converts into scrolls. You need two for the Bellows.
How to build the Bellows and smelt the Lenses
The Bellows is not a single-use quest item. It stays attached to the furnace and also enables Alchemy Flasks II, so leave it in place once Crystal Clear is done.
Hand the optic glass to the Manager at the Main Pier
Carry the finished Lenses into Town and walk out to the Main Pier. The Manager sits behind his counter at the dock. Talk to him and choose Give lenses, then close the conversation with Leave.
Completion is confirmed when the journal changes to “Quest finished” and displays its final line: a new trade ship reaches the Main Pier once a week. That recurring vessel is the errand’s whole purpose, making the pier a regular trading stop instead of a map dead end.
If you built the Bellows before picking up the quest, the delivery is instant, since the Lenses can be smelted at any point after the Metallurgy unlock and simply sit in your inventory until the Manager asks for them.
