Bringing measurements together with observations from the scene.
About CalciTrace
A research and development project connecting gypsum board calcination with practical fire investigation.
CalciTrace explores how fire changes gypsum board and how these changes can be documented and measured. The work brings together experimental fires, scene observations and the development of a handheld measuring instrument.
The project is led by Jakub Baca, a fire investigator and doctoral researcher.

The method
A laser-projected grid identifies where to measure. The handheld instrument measures calcination depth at the intersections.
Laser grid · point-by-point measurementRecord the room, fire patterns and the position of furniture before selecting the measurement area.
Use the intersections of horizontal and vertical laser lines to locate measurement points. Stand to the side to keep the grid visible.
Record the readings in their spatial order and compare the resulting depth map with observations from the scene.

Gypsum board & fire
White burn areas, blackened surfaces and intact paper facing can appear side by side. An annotated photograph explains these differences in a real fire scene.
