Internal degradation agents are those related to the object itself, i.e. with the support material, workmanship, or materials.
In objects with wooden support, these agents are connected to the type of wood and its quality, the type of fiber (which depends also on the type of wood), the glues that may have been used (if at all present). Further damage to the objects may be caused by an acceleration of the degradation of chemical residues which have not been properly disposed of at the time of manufacture, the natural movement of the wood (shrinkage and contraction) that can cause damage to a point that it can no longer carry them out normally.
These internal degradation agents cannot be eliminated, but the correct exposure conditions, handling, and storage can minimize their actions.
External degradation agents are those present in the...
