Oddy Testing

What is Oddy Testing?
Developed in 1973 by British Museum conservator, Andrew Oddy, the procedure tests the gasses emitted by a particular material in a sealed environment. Unknown (or untested) materials placed inside a sealed exhibition case or storage container could produce harmful gasses over time, affecting the enclosed artifacts. To avoid causing permanent or costly damage to your objects we can test any material you are considering.

How does it work?
We will place a sample of the material in a sealed container with three metals—silver, copper, and lead—and a small amount of distilled water. The container then goes into our dedicated oven at a constant temperature for approximately one month. The metals will display signs of corrosion if the presence of harmful chemicals is detected in the test material. A control container with the same metals is also conducted to verify that the test is valid. We will contact you with the results as soon as they are available.
