In this work, the mechanical properties of seven animal glues commercially available for conservation practice are compared. The performance these materials within ranges temperature and relative humidity commonly found in uncontrolled environments was quantified on cast glue films using dynamic analysis (DMA) tensile testing. applied experimental protocol resulted identification phase transitions between glassy rubbery states evaluation those stiffness, viscoelasticity, strength, strain at...
The mechanical response of an embedded acrylic-based paint was analyzed using quasi-static and dynamic nano-indentation. aim this study to propose evaluate a methodology for selecting indentation test parameters characterizing the properties cross-sectional samples, particularly with respect inherent issues embedding materials. experimental measured reduced modulus (Er), storage (Er′), creep (CIT) samples compared results those obtained reference free-film sample. Although nano-indentation...
This experimental program, implemented by the Managing Collection Environment Initiative at Getty Conservation Institute, has provided data about response of historic objects to changes in relative humidity (RH). Alongside other less sensitive documentation techniques (visual observation, physical measurements, photography, and 3D scanning), acoustic emission (AE) was monitored for six historic, museum-like wooden exposed gradually increasing RH variations. Quantitative calibration AE...
During the Medieval period, over 1000 stave churches were thought to have been constructed in Norway. However, currently, only 28 of these remain and 19 still distemper wall paintings. The cultural significance structures, more specifically their elaborate paintings, has changed time, as means methods for preserving monuments. Deeper knowledge current state along with environmental monitoring modeling will open way a better understanding preservation. This paper presents case study unheated...
The presented research examines 17th century distemper paint from the polychrome wooden interiors of two Norwegian stave churches: Eidsborg and Heddal. For first time, inorganic organic components specimens Heddal were identified using X-ray Diffraction (XRD), Environmental Scanning Electron Microscopy (ESEM)—Energy Dispersive Spectroscopy (EDS), Fourier-Transform Infrared (FT-IR) spectroscopy, Enzyme-Linked Immunosorbent Assay (ELISA), Gas Chromatography-Mass Spectrometry (GC-MS) after...
This study focuses on the use of micro-sensitive methods – nanoindentation, dynamic water vapour sorption, and X-ray microtomography to examine physical properties small volumes artists' materials. The novel methodology proposed in this paper was tested laboratory-prepared chalk-based ground samples subsequently applied distemper paint taken from polychrome walls Eidsborg stave church. article discusses key parameters that can be used inform macro-sized mock-ups mimicking mechanical...
Abstract Nanoindentation and dynamic mechanical analysis were used to measure changes in the surface bulk properties of Winsor & Newton Yellow Ochre oil paint films following exposure deionized water, aliphatic mineral spirits (Shellsol D40™), D5 silicone solvent (decamethylcyclopentasiloxane). ochre exposed selected solvents by 24-h immersion, sponge-cleaning. immersion deionised water Shellsol D40 caused measurable properties. However, there no or sponge cleaning.
A methodology was developed to address challenges associated with the use of nanoindentation characterize small volumes soft-matter thin films, encountered in many research fields including heritage conservation. The is based on a flat-punch indenter, whose radius so dimensioned be able predict effect substrate rigidity using an existing solution independently film's Poisson's ratio and frictional characteristic. mechanical response analyzed minimally strained condition at onset full contact...
Understanding the mechanical behaviour and properties of artists' materials is helpful for evaluating failure their structures during exhibition in confined spaces. Generally, macro-sized mock-ups are conventionally used to approximate historic materials. Although with newly adopted small-scale engineering methods, such as indentation, features can now be directly exploited from micro-sized samples taken artworks. When preparing indentation tests a set empirical rules often followed,...
