The study of cyclododecane as a temporary barrier in the molding of stone sculptures and ornaments
This paper describes the study of the hydrocarbon cyclododecane (C12H24) and its suitability as a temporary barrier in the moulding of petrous pieces of different porosities. For this purpose, two types of petrous materials were chosen, Bateig biocalcarenite from Novelda (Alicante, Spain) and marble...

| Sumario: | This paper describes the study of the hydrocarbon cyclododecane (C12H24) and its suitability as a temporary barrier in the moulding of petrous pieces of different porosities. For this purpose, two types of petrous materials were chosen, Bateig biocalcarenite from Novelda (Alicante, Spain) and marble from Estremoz (Evora, Portugal). The moulding process of a work of art is a very complex task entailing an exhaustive study of the piece and the selection of the most ideal barrier to prevent the presence of residues and unwanted chromatic changes over time. Therefore, the intervention methodology was based on both the preparation of petrous specimens with different dilutions of CDD and subsequent testing samples to study their accelerated ageing by irradiation with ultraviolet light. The results were obtained with colorimetric measurements and Fourier transform infrared spectroscopy (FT-IR). When using CDD as a temporary barrier on different types of stone, we observed some very important properties in relation to other more generally used mould-release agents; its sublimation capacity prevents the presence of residues and chromatic changes, thus making it one of the most promising substances in the field of Conservation and Restoration of Cultural Property. |
