Main characteristics :

Do paper is characterized as porous, light, durable, not smudge when writing and drawing, less prone to termites, or brittle fracture and crushed by humidity.

Do paper is porous and light due to materials used to make it, the actual process of making it as well as the material handling, and finally thanks to regulations of Do paper production technology. Do paper has a fibrous structure; the tiny fibers hold together like spider webs with multiple layers, not in the order of weft like silk weaving, but move in the form of brown multi-dimensionally. The specific gravity of Do paper is roughly half of the industrially produced papers.

Yen Thai Do papers have been exporting to many countries in the world and favored by customers. The French painters used Yen Thai Do paper (large size) to paint in Indian ink with the method of classical oriental paintings. A few museums in Europe also used Do paper to strengthen the back of the paintings. With high moisture resistance characteristics, Do paper prevents the works of art to get moldy.

Durability :

The durability of Do paper reaches an exceptional level in gold leaf production technology. Gold leaves are produced in Kieu Ky village, Gia Lam (Hanoi). Gold bullions are inlaid into gold leaves, which are about 1-2 mm thick. Gold leaves are cut into small pieces (about 1 or 2cm). Do paper is used to wrap gold layers: we always put a layer of gold over a layer of paper. Then a small iron hammer is used to beat continuously a stack of Do papers on a flat anvil until the gold leaf is laminated to the smooth and extremely thin powder layer of gold powder, which is a valuable material for gilding on lacquer products (Buddha statues, distichs, horizontal lacquered board, altars, palanquins,…). Painters always use gold and silver leaves to gild these precious products. They are painted when wet, not yet dry and then dust of gold and silver leaves are blown on to gild with bright colors. It is worth mentioning here that Do papers, which are used to wrap gold leaves, aren’t torn at all.

At the National Storage Center, of all the paper documents, the ones made of Do paper have the highest life expectancy. Do paper documents are among the documents that have the oldest production, since the methods of preserving was undeveloped.

  • Color catching, hygroscopicity and moisture removal: Due to the porosity, Do paper is easy to catch color when writing, printing.
  • Heat Insulation, sound insulation, sound evaluation, fire masterpiece: just due to porosity Do paper has good heat insulation, and due to the multi-dimensional fibrous structure, Do paper has good sound insulation.
