Burning Glass
Spoilers Ahead
This page contains spoilers for the Workshop. View at your own discretion.
The Burning Glass is a special item in Blue Prince. Unlike most contraptions, it does not serve the purpose of either of its components, instead offering an entirely different utility.
How to obtain
As a contraption, the Burning Glass can only be obtained in the Workshop by combining the Metal Detector and the Magnifying Glass.
Usage
The game contains several objects which can be lit by the Burning Glass. Many of these are ruby socketed candlesticks, which are usually found in pairs and trigger some permanent effect when all are lit. The candles themselves do not usually remain lit on future days, and can be re-lit on future days with no additional effect. Several other ignitable objects exist such as fuses, and have various other effects when lit which may or may not be permanent.
Spoilers Within
This section contains spoilers for all uses for the Burning Glass.
Crate Tunnel
The Crate Tunnel contains two wall-mounted torches near the crates. Lighting either torch illuminates the tunnel, allowing the nearby document to be inspected and the Tunnel floorplan to be collected. Both torches remain permanently lit on future days, even if only one was lit.
Chapel
Lighting both of the candles in the Chapel permanently reveals the Keeper of Tithes, which can be broken by hand to regain all previously taken Chapel gold. Unlike most ruby socketed candles, these candles stay permanently lit once both are lit, and cannot be interacted with again.
Freezer
All of the ice in the Freezer can be thawed with the Burning Glass, granting access to the documents and items inside. This includes:
- A frozen key and two frozen gems
- A frozen sheet of ice concealing a doorway, leading to a hidden chamber containing an Upgrade Disk and note from Denny Revane
- The contents of the cooler, usually a Prism Key and a letter from Herbert Sinclair
Unlike other burnable locations, this thawing is only temporarily and the items, documents and ice wall will be refrozen on future days.
Tomb
The Tomb contains two pairs of lightable candles. In both cases, lighting both candles raises a hidden wall to reveal a hidden chamber, which remains open permanently.
- The first location is immediately to the left after entering the main chamber and contains a table with an Upgrade Disk and 4 dice inside. On future days only 2 dice spawn, as well as the Upgrade Disk if it has not been used.
- The second location is at the far end of the main chamber and contains the resting place of Clara Epsen, easily identified by her portrait on top. Unlike most photographs of Clara Epsen, it cannot be inspected. There is a Diary Key partially hidden behind the portrait, as well as a note written in Erajan on a table.
Trading Post
The dynamite fuse on the left side of the Trading Post can be lit, creating a hole in the west wall of the room.
The other side of the wall contains a hidden chamber with a still for producing moonshine. On the barrels are an Upgrade Disk, 40
spread across eight piles, and related documents. The hole in the wall is permanent, though the coins do not spawn again on future days even if they were not taken.
Abandoned Mine
A circular room in the Abandoned Mine contains eight candles. When all eight are lit, a path opens to The Precipice. If both entrances are opened, this can be taken as an alternative path to access this area.
These ignitable objects are tied to major puzzles or other lategame content:

This section contains spoilers for very secret burning locations.
Apple Orchard
The base of the sundial in the Apple Orchard can be burned with the Burning Glass, allowing turning the base to open the top. See A New Clue/Analysis#Sign Puzzle for puzzle details.
Crate Tunnel
The 6th door in the sequence of doors in the Crate Tunnel has a pair of torches, which must be lit to open the door and proceed.
Interactions
- The Burning Glass may be stored in Coat Check or retained with the Moon Pendant like any other special item. Starting the day with the Burning Glass in Coat Check, or with it already in the inventory due to the Moon Pendant, will cause the Metal Detector to be unobtainable today. The Magnifying Glass is unaffected and can be obtained like usual.
Additional information
- [Secret Shop Item: Torch] The Torch serves the same function as the Burning Glass, allowing them to be used interchangeably.
