from: Vietnam Heritage
Due to the harsh weather and endless wars, a big part of Vietnamese art heritage has been destroyed. What remains are large architectural and sculptural works made of durable materials such as stone and wood. The few surviving of silk paintings are the portraits of Nguyen Trai, Phung Khac Khoan and some paintings used for worshipping. A silk painting is a painting on silk.
The Indochina College of Arts was opened in 1925. The Vietnamese artists at that time studied oil paintings and learned Western painting techniques. Few painted on silk. The tendency of silk paintings at the time was to use simple colours. Brown and black were employed for dark tones; the light was the colour of silk. The paintings were closely laid-out with big characters and little colour. In 1957, silk painting was officially introduced into the college’s curriculum. The silk itself is fragile and fine. Silk painting artists seldom used light as oil painting artists did. The light in the silk painting was created by the harmony and the nuances of the colours as well as the arrangement of the gamut of the artist. The paintings had their dynamic rhythms which evokes certain emotions, as do light and shade.
The Chinese artists used to paint using ink and the colours made from soil and rock. The Vietnamese usually painted using water-colours. The silk painting techniques in Vietnam were the combination of scientific techniques from the European countries combined with the national artistic legacy. Vietnamese artists manipulated water-colours over the surface of the silk. Sometimes they wetted the silk with water before they painted with colours. Some artists even poured the water over the painting after they finished it for the dregs of the colours to be washed away before they continued. These artists had to use a frame to stretch the silk on to work instead of spreading the silk on a board as the Chinese artists did. The frame did not need to be as thick and sturdy as the one for regular cloth for oil painting, since the silk is fragile and does not need to be stretched too hard. After the silk piece has been stretched on the frame, the artist uses a broad-based pen brush to brush the surface of the silk with water to make the silk slack. In order for the silk to be painted on without getting blurred, the silk needs to be starched up. For the silk to be starched up, the artist uses the rice water taken out when the rice is boiling, blends it with some alum, then uses a broad-based brush to brush mixed liquid over the surface of the silk. When the starch dries up, the artist uses a clean brush to drip a drop of fresh water on the surface of the silk to check. If the water gets absorbed into the silk without getting blurred, it is ready for the artist to work on. After he has sketched on paper, he redraws the picture over the outline using black ink or a dark black pencil on the paper, then puts the paper under the silk for drawing. There is an advantage to drawing on a piece of silk stretched on an easel; the artist can move away from it for a check, but there is also a draw-back-the colour might drip down the surface of the silk. Two canisters of water are needed, one to wash the brush and one to brush water over the surface of the silk to keep it humidified. When he draws, the artist needs to be careful, for once painted, the colours will get into the silk fibres and make it difficult to erase. The water-colour is not like the oil paint or coloured powder, tempera or acrylic. Water-colour can be used to cover a line. Once a black stroke has been laid down, it can’t be changed into a white one.

Losing the old way
The first silk paintings came from China and date back to approximately the third century AD. Of course, silk paintings could have been produced long before that, but silk is not a long-lasting material. In order to keep silk paintings for long periods of time, people painted on a length of silk with natural colours and only unfolded them occasionally, which allowed them to be kept as long as one thousand years. Eventually, careers in copying paintings and archaic letters took shape, and every several hundred years, paintings and books were copied.
Artists from the Indochinese Arts School and their successors stopped using natural colours and used water-colours on the silk instead. After they had finished their paintings, the artists used paste and strengthening paper on the backs. This had basically changed the technique of the traditional silk painting. Using natural colours, the artists didn’t wash and brush the surface of the silk. With water-colours, the artist actually dyes the silk. The water- colour is absorbed into the fibre of the silk instead of staying on the surface. Using this technique, the artist has to paint wet and wash it several times.
