How to Use Burning Glass in Blue Prince

Blue Prince is a game filled with mysteries, hidden items, and intricate puzzles. One of the most useful tools you can craft is the Burning Glass, a versatile item that helps uncover secrets, reveal hidden pathways, and even unlock the elusive Study Safe. If you're struggling to find all its uses or decipher the safe's code, this guide will walk you through everything you need to know.

How to Craft the Burning Glass

Before you can start uncovering secrets, you’ll need to create the Burning Glass. Here’s how:

Gather the Required Items:

• Magnifying Glass (found in the manor)
• Metal Detector (another key tool found early in the game)

Combine Them at the Workbench:

• Head to the Workroom (or any available crafting station).
• Place both items on the workbench and combine them.
• The Burning Glass will appear—pick it up and add it to your inventory.

What Does the Burning Glass Do?

The item’s description states that it can:

• Ignite certain surfaces (like torches, candles, and even explosives).
• Light unlit candles to reveal hidden clues.
• Defrost frozen objects (such as the freezer in the manor).
• Interact with environmental puzzles (like the Sundial in the Orchard).

Now, let’s explore where and how to use it effectively.

Where to Use the Burning Glass in Blue Prince

The Burning Glass has multiple applications throughout the manor and its surrounding areas. Below is a detailed breakdown of all known uses:

1. Lighting the Torches in the Tunnel

• Location: Exit the manor and head left of the Fountain, then descend the stairs.
• What You’ll Find: Four blue flame pillars (assuming you’ve already lit them).
• Hidden Tunnel: Turn around from the platform to spot a tunnel in the rock face (if it’s sealed, you may need to unlock it first).
• What to Do Inside:
  • Use the Burning Glass to light two unlit torches.
  • This reveals a hidden floorplan for your drafting pool.

2. Lighting Candles to Uncover Secrets

There are several candle-based puzzles in Blue Prince that require the Burning Glass:

• Underground Candle Circle:
  • Near the Tomb entrance and mine cart area, you’ll find a circle of unlit candles.
  • Light them all to trigger a hidden event or reveal a clue.
• Chapel Candles:
  • Inside the Chapel, light the candles to uncover a hidden message or item.
• Reservoir Room Candles:
  • Another set of candles can be found here—lighting them may affect the room’s mechanics.
• Crate Tunnel Candles:
  • Some candles are hidden in a tunnel filled with crates—lighting them could reveal a passage.

3. Interacting with the Sundial (Orchard Puzzle)

• Location: Head to the Orchard where the Sundial is located.
• What to Do:
  • Use the Burning Glass on the Sundial at different times of day.
  • This may cast a shadow revealing a hidden code or symbol related to other puzzles.

4. Defrosting the Freezer

• Location: The Freezer in the manor (exact location may vary).
• What’s Inside: Frozen gems, keys, and other valuable items.
• How to Access Them:
  • Use the Burning Glass to melt the ice blocking the freezer’s contents.

5. Blowing Up the Trading Post (TNT Puzzle)

• Location: The Trading Post has a stack of TNT inside.
• What Happens:
  • Light the TNT with the Burning Glass to trigger an explosion.
  • This could unlock a new area or reveal hidden loot.

How to Unlock the Study Safe

Now, the big question: How do you find the Study Safe code?

Step 1: Locate the Safe

• The Study Safe is typically found in the manor’s Study Room (exact location may vary).
• It requires a 4-digit code to open.

Step 2: Finding the Code

The code is hidden in environmental clues—here’s how to uncover it:

Check Lit Candles & Torches:

• Some candles, when lit in a specific order, reveal numbers.
• Revisit the Chapel, Reservoir Room, and Underground Candle Circle for hints.

Examine the Sundial Shadow:

• The Orchard Sundial may display a number sequence at certain times.

Look for Hidden Notes:

• Some floorplans or documents found using the Burning Glass may contain partial codes.

Defrosted Items in the Freezer:

• One of the frozen objects might have a number etched on it.

Step 3: Input the Code

Once you’ve pieced together the digits (common codes include 1972, 1865, or 0423), enter them into the safe to unlock:

• Rare gems
• Keys to restricted areas
• Important story documents

Final Tips for Using the Burning Glass

• Experiment with every interactable object—some surfaces may only ignite under specific conditions.
• Revisit areas after lighting candles—some secrets only appear after flames are lit.
• Combine with other tools—the Metal Detector may help find hidden metal objects near burnable surfaces.

With this guide, you should now have everything you need to master the Burning Glass, unlock the Study Safe, and uncover the deepest secrets of Blue Prince. Happy exploring!
