Roman plasters sampled from different houses at the archaeological site of Herculaneum, Italy, (2010–12) were studied by means of petrography, thermal analysis and X-ray ﬂuores- cence. Herculaneum plasters are composed by preparatory layers (arriccio) with a thickness of several centimetres and are based on a calcitic binder and volcanic scoriae as aggregates, covered by a thin ﬁnal layer characterized by a low granulometry. Most of the sampled plas- ters can be placed into two groups based on the aggregate composition and classiﬁed as marmorino or intonachino. However, a similar aggregate composition did not induce superim- posable thermal behaviour, thus suggesting that the samples underwent different ageing/weathering processes, with a consequent change of the ratio among the components.
