Project description

This project, proposes an interdisciplinary multi-scale study of the gilding materials and techniques in Portuguese wooden decorative art (“talha dourada”) covering a range of time from c.1500 to c.1800. This study will consider the complexity of materials and techniques used in gilded artefacts inPortugalfrom a different analytical perspective, at various scales of characterization (Macro, Micro, Nano), including innovative tools for dissemination and Outreach activities in conservation and artistic studies field.

Besides the historical and technical research of the existing literature and treatises on gilding, the project will focus on the experimental study, diagnosis and conservation of gilded wooden art-objects, in diverse techniques along the historical époques considered.

Aimed to deepen the scientific knowledge about gilding materials and techniques in Portuguese “talha dourada” artefacts, the project is focused on the design of an overall interdisciplinary multi-scale methodology combining the historical research with analytical methods of study, having as final outcome the implementation of the results in the form of a multimedia tool, GILT-Teller. Beginning with first year of the project, a multimedia tool – GILT-Teller – based on interactive animation softwares and website, will be designed as a virtual trip into the gilding materials and techniques. The implementation of the multimedia tool into training programs and cultural activities will enhance the public awareness on the importance and implications of conservation and scientific research related to “talha dourada” artefacts inPortugal.

The main Objectives are the following:

  • Search the literary sources describing the gold's use and its application as gilding layers in religious works of art inPortugal;
  • Understand  which was the development of manufacturing techniques of gilding up to 19th century;
  • Analyze the chemical composition of each layer constituting the polychromy of “talha dourada” decoration (from the ground to the final finishing varnish or glaze);
  • Study the influence of the wooden support finishing (“tosco”) on the final appearance and behaviour/resistance of gilded surfaces;
  • Study the influence of the sizing and other organic layers/components on the overall stability of the polychrome structures;
  • Differentiate between the original materials and layers in the structure of the polychromy and the ones added with posterior treatments or interventions;
  • Understand which are the relationships between gilding materials and techniques and the degree of erudition of the studied works of art?
