The laboratory pillars use four specific items in fixed corners; this spoiler-marked answer gives the complete placement.
For the Suncraft laboratory pillar puzzle, place Magma in the top-left, Gold Bar in the top-right, Glass in the bottom-left, and Grape in the bottom-right. Read the positions from the front of the four-slot laboratory panel.
Spoiler: exact pillar placement
| Position | Required item |
|---|---|
| Top left | Magma |
| Top right | Gold Bar |
| Bottom left | Glass |
| Bottom right | Grape |
Use the layout in the correct orientation
Face the panel so its two upper and two lower positions form the same square shown in the interface. Place the upper pair first, then the lower pair. This reduces the chance of swapping left and right after rotating the camera.
The current answer comes from a Steam Community solution to a player blocked on the laboratory pillars. It is not a generic crafting recipe: each material belongs to a position. If your screen has more than four slots, different labels, or a panel outside the laboratory, stop rather than forcing this arrangement into a different puzzle.
Evidence boundary
The checked solution establishes the four final placements, not a fastest farming route for the ingredients. If one of the four named items is missing, this page cannot supply a verified location without separate current evidence.
Achievement check
Steam describes Riddle Master as solving the book, torch, and pillar riddles. Finish the Suncraft book riddle and Suncraft torch puzzle if needed; the Riddle Master page identifies which named requirement is missing.
