Where might you find it?

Mould can potentially be found on any object material. Although it grows in organic materials (for example, leather, paper and textiles) it can also grow in the layers of dust and dirt on top of inorganic materials such as metal and glass. Therefore, it will exist in every kind of museum collection.

In the UK, typical conditions for indoor mould growth occur in temperatures between 10 – 35°C and a relative humidity of above 65%.
