Week 8 of 12 
Module 5: Conservation Interventions and Treatments; Criteria for Selection and Implementation 
The Study Tour: Venice

This morning we left Parma for Venice. We arrived around midday and met Paolo Pagnin, a stone conservator with Lithos Restauri (another of our predecessors having taken the ICCROM Stone Conservation Course in 1985). The main focus of today was our visit to the Basilica di Santa Maria Gloriosa dei Frari (Church of the Frari) where Paolo has been involved in many separate conservation projects. 

More details to follow...

We visited the Chiesa di Santa Maria dei Miracoli which is thought by many to be one of the most beautiful churches in Italy. It has many issues with moisture damage due to its position directly beside a canal. Inside it is possible to see the difference in damage between the canal side and other side of the chapel. On the facade of the church there is a sculpture above the doorway which was fully immersed in epoxy resin for consolidation but it is expected that the sculpture will turn more and more yellow over time due to the alteration of the epoxy.

We continued to wander around Venice and paused at the Chiesa di Santa Maria Formosa where we observed the results of some cleaning trials that had been carried out.
