Roof Tiles and Bricks

Investigative research on roof tiles and bricks is categorized by the natural scientific analysis method, form classification, and chronological estimation through an investigation of designs and patterns.

Natural scientific analysis

Analysis methods for investigative research on roof tiles and bricks include physical characteristic analysis, chemical characteristic analysis, and plastic temperature estimation analysis.
The following images show an X-ray diffraction analyzer and differential thermal analyzer, two of the major analyzing devices used in plastic temperature estimation analyses, with an example of analysis shown.

Design and Pattern Investigation

A comprehensive analysis on types, specifications, and excavation locations of roof tiles is performed through a design and pattern investigation, and the roof types of structures, sizes of structures, and construction locations of roof tiles can be estimated during structure restoration research.

Metals

Various major methods are used for investigative analysis of metals, including macroscopic investigation which performs morphological investigations including visual inspection, micro-structure observation utilizing a metallographic microscope, X-ray image, X-ray Fluorescence Spectroscope (XRF), X-ray Diffraction Analysis (XRD), Scanning Electron Microprobe Analysis (SEM), and others. The table below shows the results of observation of micro-structures in traditional metals, which were collected at the site of the Sungnyemun Gate fire incident.
