The 8th Conservation- Restoration Workshop in the Sisak Steelworks Sculpture Park took place in Sisak, Croatia, from 17th to 23rd June 2019. The workshop was organized and led by Sagita Mirjam Sunara (University of Split). Sisak Municipal Museum provided a space for lectures, and the Museum’s conservator-restorer Neven Peko transported the participants to and from the sculpture park. Accompanied by Moira Bertasa, researcher at the Chemistry Department of the University of Turin, five conservation-restoration students from Turin participated in the workshop: Anna Collarin, Valeria Gugliermina, Gaia Pachì, Cristina Scarrone and Camila Ayelen Restrepo Capera.
The workshop included lectures, discussions, problem-based assignments and practical work. A number of topics were covered: history of the Sisak Steelworks Sculpture Park and of the efforts to preserve it, risk assessment for outdoor sculptures, routine maintenance, dismantling and transport of large-scale sculptures, and graphic documentation of outdoor sculptures.
The hands-on session of the workshop included cleaning of the sculptures from the Sisak Steelworks Sculpture Park. The Sisak Public Fire Department provided a fire vehicle with a water tank for the washing of the sculptures. The Fire Department also provided a vehicle equipped with very large ladders so that taller sculptures could be washed and samples taken from them. The municipal grounds maintenance service provided help with the cleaning of the sculptures’ concrete plinths.
During the workshop students also gained practical experience in sampling, as they helped Neven Peko to collect samples of coatings and corrosion products from the sculptures. This work was related to WP3.
