Conservation work is guided by a number of basic principles. Apart from the "less is better" approach mentioned above, the most important principle is that the materials and methods used in conservation must be reversible. It should be possible to remove or undo, with damaging the object, anything that was previously applied or done.
目前修護的原則，除了前面所說「少即是多」之外，最重要就是修護的材料及手法都力求是「可逆性」的，也就是日後都可以移除和還原，而不會傷到器物本身。
