The internship project took place at the company Muñoz de Pablo S.L. located in Segovia (Spain). This company is devoted to the conservation and restauration of stained glass. The main goal of this five-month internship project was the learning and knowledge improve of the stained-glass conservation and restoration both in workshop and within rehabilitation of in situ works.
The conservation and restauration work focused on two artworks, namely the Niño Jesus hospital and the skylight of a palace located in the San Marcus street, both in Madrid. These two case studies had several structural problems and adhered surface dirts.
All conservation proposals presented are in accordance with the conservation and restoration Code of Ethics following the principles of minimum intervention thus respecting the integrity and historical value of the work, as well as the principle of reversibility of treatments.
The intervention carried out in Niño Jesus hospital case study can be considered a previous emergency treatment in order to ensure the conservation of the stained-glass in higher risk, since the intervention in the entire set will take more four years to be finished. On the other hand, the intervention in the skylight of the Calle de San Marcus palace was programed within the building’s rehabilitation.
Both interventions allowed us to understand all phases and procedures related with the conservation and restoration treatments of stained glass such as: previous documentation, in situ removal, photographic record, transportation to the workshop, intervention, reassembly of the sets, outside protections application, and also, the specificities of each work in the context of conservation and restoration or rehabilitation
The intervention allowed, in both cases, the restoration of the aesthetic reading of the stained glass and recovery of its original functionality.
