Painted stuccoes were investigated for fire damage by microscopy and analytical study
- class="label">•
Heat-induced effects were mineral phase changes affecting plaster microstructure and colour
- class="label">•
Cracks and microcracks were produced by dehydration of gypsum binder and thermal shock
- class="label">•
Thermally induced chemical reactions involved pigments
- class="label">•
Fire damage on paint surface consisted of colour change and/or disruption of painted layers
