why is it recommended to varnish an object made of papier mache
Answers
Papier mache is a craft in which paper and adhesives (like glue) are used to create objects. It is a common practise to varnish papier mache creations.
Varnish is a liquid that is applied on the surface of objects. These two functions make varnish a part of papier mache projects:
1. To protect the object- This is a structural function. It gives strength to the structure of the object. When the varnish dries, it hardens. This hard layer protects the object from water, accidental scratches and even the humidity in the air.
2. To add lustre or shine to the object- Once dry, the transparent varnish imparts a sheen to the object, adding to its aesthetics without hiding any of its beauty.
One does not always have to varnish papier mache objects, however, it is highly recommended since it adds to the life and beauty of the object.
