Objectives

  • Know the critical parameters to be controlled in order to measure pH and conductivity of different types of surfaces precisely and accurately
  • Becoming familiar with the measurement method
  • Knowledge of conservation issues related to the acidity and salinity of artefact surfaces
  • Acquire skills to deal with the cleaning of water-sensitive surfaces

Description

The course combines a theoretical module and a workshop to be held in the laboratories of the Conservation and Restoration Centre ‘La Venaria Reale’.
Module 1 (theoretical lessons) will be held online on CCR Digital Lab or in person at CCR on Thursday 11 July 2024, from 2 to 6 pm CET.
In case you are interested in attending in presence, please write an email to training@ccrdigital-lab.it to confirm your booking.
Registration for module 1 is mandatory for participation in module 2 (workshop).
Module 2 (workshop) will be held on Friday 12 July 2024, in two turns:
- 9:00 to 13:00 CET (first group)
- 14:00 to 18:00 CET (second group)
Participants will be assigned to the morning or afternoon session based on the order of registration. If there are specific needs, participants may indicate a preference by sending an e-mail to training@ccrdigital-lab.it.

Precise knowledge of the acidity and salinity of surfaces allows you to work more confidently with aqueous media. In the theory session, conservation issues and fundamental scientific knowledge around the concepts of acidity and salinity of water-sensitive surfaces will be addressed.

During the lecture, participants will also be shown step-by-step how to accurately measure the acidity and salinity values of the surfaces to be treated, examining the most common technical issues and errors made when measuring pH and conductivity.

During the workshop, participants will be able to put into practice what they learnt during the theoretical lecture, acquiring technical skills through practical exercises: preparation of materials, precise, replicable and reliable methods of measuring pH and conductivity of water-sensitive surfaces.
