‘When the books don’t dry flat, wet them again, and flatten them out,’ Moczarski says through her mask, and shocks her listeners by pouring water over an old book. ‘The mould can be dabbed off with a concentrated alcohol.’
She also wears gloves: mould is dangerous, and can cause asthma and serious lung disease.
After the book is flattened, it should ideally be freeze-dried. An audience member asks how much the machine for freeze-drying costs. ‘400,000 euros,’ Anders says.
