(591PED/2022)

As the degradation processes of cultural heritage objects remain inevitable, the continuous development of advanced materials able to counteract specific degradation processes is also necessary. Thus, are needed thorough scientific studies in order to develop tailored formulation, in order to protect, preserve, and restore cultural heritage objects, and this represents a continuous challenge for the scientists, aiming to replace the current rather serendipitous approaches in restoration.

Project goal

The main goal of the project is to develop novel multi-layer composite materials with multiple functions (consolidation, self-cleaning and anti-microbial) applicable for the conservation of different inorganic substrates.

Summary

Since the degradation processes of cultural heritage objects remain inevitable, the continuous development of advanced materials capable of counteracting the specific degradation processes is necessary. Thus, thorough scientific studies are needed to develop a customized formulation to protect, conserve and restore cultural heritage objects, and this represents a continuous challenge for scientists, aiming to replace current approaches in restoration, which are rather under the specter of serendipity.

The InHeritage project thus aims to develop new multilayer composite materials with multiple functions (consolidation, self-cleaning and antimicrobial effect), applicable for the preservation of various inorganic substrates. The solutions developed in this project will represent not only an alignment with international concerns in the field, but also a very important, innovative technical solution at the national level, which will contribute to the sustainability of the project after the implementation period.

The activities expected to be carried out by the consortium during the first year of implementation were:

  • Act 1.1 – Identification of pilot areas, representative at national level; signing protocols with local authorities regarding full access to cultural heritage sites, if applicable.
  • Act 1.2 – Evaluation of the most common types of degradation encountered on stone objects from the cultural heritage (monuments, vernacular constructions, etc.) in the pilot area; taking samples of cultural heritage objects; identification of microorganisms that affect cultural heritage objects in the pilot areas
  • Act 1.3 – Development of model substrates for further studies
  • Act 1.4 – Establishing the most suitable consolidant for each type of support material in the pilot area.
  • Act 1.5 – Dissemination of the results and the project

The proposed activities were carried out in full, supporting the continuation of the project in 2023. Thus, pilot areas were identified (by signing collaboration agreements with several museum institutions) that were studied to identify the main causes of the degradation of vernacular buildings and monuments. Several types of model substrates were identified, on which consolidation studies were started, using the most suitable recipes, according to the literature study.

The obtained results were disseminated within the scientific community, the results of the dissemination being widely presented on the project website (Romanian version – https://icechim.ro/project/inheritage_ro/, English version – https:// icechim.ro/project/inheritage_en/).
