Oddy test lecture and workshop

Do you work with the storage, display, transport, or packaging of collection objects? Are you interested in understanding how the materials used for these activities might affect collection objects? Then the Oddy test might be a useful tool for you!

The Oddy test can help to indicate if a material emits pollutants that can be harmful to cultural heritage collections. Materials of interest are often those used for display, storage, transport, or packing. Join the Heritage Laboratory at the Swedish National Heritage Board online or in person to learn about the Oddy test, gain some practical tips, and figure out if you can perform Oddy tests at your own institution.

When: 8 – 9 November 2023.
