How do we preserve the calligraphy and paintings？
2 min readEnvironmental pollution causes damage to calligraphy and paintings.In cities，the air has high acid and alkali elements due to car exhaust and industrial pollution.These harmful elements and dust usually deposit onto the paper on which calligraphy and paintings are executed.If these things remain on the paper for a considerable period of time，they will erode calligraphy or paintings.Following are some necessary points that help you preserve your calligraphy and paintings.
a.It is better to clean paper-based calligraphy and paintings once a month.If you use a hairdryer for this effort，first of all，hold the hairdryer 10 to 15cm away from the paper and let the end of the hairdryer face the paper at an angle of30 degrees.Sweep the paper with a soft brush while the hairdryer works，blowing out natural wind towards the paper.A chicken feather duster is also available to gently brush off the dust.Don’t use a piece of rag for the cleaning.
b.Hang calligraphy and paintings twice a year，each time lasting no more than two months.Then store these artworks for the rest of the time.
c.Store these artworks in places，which are fireproof，bookworm-resistant and moisture-proof.Mothballs or camphor balls are commonly used for protection against bookworms.The wooden case，made of camphorwood，is an excellent choice for the storage of calligraphy and paintings because camphorwood itself has a mothproof attribute and fine air-tightness.
d.Place all the artworks to be suspended inside the case，with a desiccant agent，mothballs or camphor balls below no matter what kind of box or case is used for storage.
e.The suitable temperature for storage is between 14℃ and 18℃；the suitable humidity is between 50%and 60%.Avoid high temperature，high humidity and heavy pressure.
