June 10 - 12, 1:00 - 3:00 p.m. EDT, Online
Virtual Annual Meeting Workshop
Instructor: David Thicket
Significant improvements have been made in in performance, guarantees, and pollution measurement of showcases, although these updates are not widely known across the conservation community. This workshop will present improvements, as well as a series of low to medium cost measurement options. A recent survey found most cultural heritage organizations do not measure pollution, with knowledge and cost being principle barriers. The freely, online MEMORI Decision Support Tool was designed to overcome these barriers and provide accessible and interactive information.
Many metals are sensitive to pollution, as they are to humidity. This workshop will explore the management of metal corrosion, enclosures, pollution, and the MEMORI decision support model. The MEMORI project developed a series of online tools to guide measurement, assess results, and mitigate risk from the most common damaging pollutants. This workshop will guide participants through this process. Participants will learn to use low cost measurement methods including commercial diffusion tubes, A/D strips with colorimetry, and Oddy tests. The workshop will discuss how and when to undertake measurement campaigns, how to assess the results, and a series of mitigation methods used within a decision support model. Showcase assessment and refitting will be a significant part of the workshop.
Participants will gain an understanding of:
- The interaction of pollution and RH with common museum object material types
- The range of measurement options available and issues of when and where to measure
- The use of A/D strips with colorimetry
- The use and visual assessment of lead coupons and of silver coupons with colorimetry
- Interpretation of results
- Showcase performance with regards to internal and external pollution and RH
- Measuring showcase air exchange rate and leakage paths
- Using MEMORI decision support model to assess results and guide mitigation options
Participant will require access to Excel, and PowerPoint. Previous experience with these tools is not required.

He joined the British Museum in 1990, specializing in preventive conservation and inorganic materials conservation research. Joined English Heritage in 2003 as senior conservation scientist, mainly researching preventive conservation. Recent projects have focused on historic house environments, pollution and damage, collections demography and epidemiology, non destructive testing, microclimate frames and optical coherence tomography. He is an assistant coordinator of the ICOM-CC Metals Working Group, and an ex coordinator of the Preventive Conservation Working Group. He sits as a UK expert to the European Standards CENTC 346 (conservation standards) and is a directory board member of the Indoor Air Quality and Infra-red and Raman Users Groups. He has published over 100 research papers, and co-supervised 6 PhDs. He has run over 20 courses from 1 to 4 days in a variety of topics including showcases, light, materials testing, general preventive conservation, pollution, using the MEMORI decisions support model (2 workshops in past 12 months).
