Conditions for Storage and Display

Water is the most influential parameter directing the environmental attack on glass. Therefore, the optimisation of relative humidity during storage and display 

At moderate levels of relative humidity, acid pollutants accelerate the degradation of glass, notably in display cases with a high concentration of acetic acid (released from showcase materials or from other objects) where heavy damage has been reported on sensitive glasses even after exposure periods of a few months only. 

In general, it must be stressed that glass is considered as a relatively stable material, although various groups of objects do have a special need for preventive conservation. Although a large part of a particular collection might be easy to keep, inappropriate environmental conditions may cause severe
