A Closer Look at Conservation(史密斯基金会就画像藏品的收购修复过程所作的图解)

史密斯基金会提供的这段中国画修复过程的图解文章非常有趣,贴过来与朋友们分享。

标题:A Closer Look at Conservation

简介:Introduction

Step behind the closed doors of the Department of Conservation and Scientific Research to see how several portraits in the Sackler Gallery's exhibition Worshiping the Ancestors: Chinese Commemorative Portraits were restored.

Remember! These are trained professionals – don't try this at home on your cherished family portrait of your great grandmother.

Smoke, Dirt, and Mold
Most of the works in this exhibition are ancestor portraits — paintings used by families in annual rituals to venerate or worship their forebears. On these special occasions, the portraits were hung over family altars, and rituals were performed before them. Over generations of use, the paintings darkened from the accumulation of incense smoke and dirt. When they were not on view, most of the scrolls were rolled up and stored in damp conditions. Water stains and mold damaged some of the most impressive portraits.

Preparing for the Exhibition
Restoring a painting to its original condition after hundreds of years of wear and tear — and even neglect — is a time-consuming yet rewarding undertaking. A skilled professional with a steady hand, intense attention to detail, and lots of patience can almost miraculously restore a work to its former splendor.

This conservation project was made possible by the generous support of Fidelity Investments through the Fidelity Foundation.

清洁: Cleaning

配图一:Stains and dirt are obvious on the portrait and mounting.




One example of the cleaning process that was used for many of the paintings is the treatment of the portrait of Prince Hongming (see left). After many years of exposure to dust, grime, and soot from incense, the portrait had become soiled, stained, and darkened. Also, at some time in the painting's history, water soaked the upper right corner, staining the silk background cloth.

配图二:A moist cotton swab rolled gently across the surface of the pigment loosens dirt.



The surface of the painting was first cleaned with a soft brush to remove loose dirt and dust. Lightly moistened cotton swabs were then gently rolled over the painting to loosen and remove soil. Since many of the paintings are sensitive to water, great care was taken not to disturb pigments on the surface. Stained areas of the background silk were also cleaned using a vacuum table that draws water through the silk without damaging the delicate silk fiber. This process removes staining but does not endanger the pigments.

配图三:After treatment, the portrait has regained much of its original brightness and clarity.   

Detail; Portrait of Prince Hongming (1705–1767). China, Qing dynasty, 1767, or later copy. Hanging scroll; ink and color on silk; image only, 200.8 x 115.4 cm. Arthur M. Sackler Gallery, Purchase—Smithsonian Collections Acquisition Program, and partial gift of Richard G. Pritzlaff, S1991.61


After many hours of careful cleaning, the pigments appear brighter and the surface of the painting is lighter overall. The staining in the blank area surrounding the painted image is barely noticeable. We now have a better idea of how the portrait may have looked when it was first painted.

颜料防脱与平复折痕:Consolidating Pigments and Reinforcing Creases

配图一:The silk support and paper linings of this detail of the portrait of Daisan are creased and broken.


As a hanging scroll ages, it dries out andbecomes less flexible. Repeated rolling and unrolling causes themounting structure to crease or crack and eventually break. Thesecreases force the pigments on the painting surface to loosen andseparate from the silk support and cause paint losses in the image. Theextent of this problem also depends upon the age of the painting, howfrequently it was rolled and unrolled, and the quality of the materialsand techniques that the artist used. For example, in this portrait ofDaisan, a major leader during the early Qing dynasty (1644–1911), theanimal glue binder that was mixed with the painting's pigments morethan a century ago has lost its holding strength. As a result, thepigments have become powdery and easily fall from the silk surface.

配图二:A Sackler conservator uses a vacuum table to consolidate pigments of another hanging scroll.

In this case, the loose (exfoliating) pigmentswere consolidated, or adhered in place, using a traditional animal gluebinder. The solid glue was dissolved in warm water to a 1 percentconcentration and applied with a brush or sprayer over the unstablepigments. This process, which takes several hours, was repeated inareas needing better adhesion. Areas where the pigments are coarse orthickly applied were consolidated using a vacuum table (see left). Thetable's strong suction pulled the animal glue binder through the thicklayers of pigments and into contact with the silk support beneath, thusensuring stable consolidation.

配图三:The consolidated pigments of Daisan's portrait are now stable, and the crease has been reinforced.



The stabilized pigments are no longer in dangerof coming (cleaving) off the surface of the painting when the portraitis handled and displayed. The creases in the mounting support are nowreinforced with strips of paper applied from the back. These paperstrips minimize the support's effects and deter further damage to thepainting.

重新装裱:Reusing or Replacing Mounting Silks

配图一:The old mounting silk surrounding this portrait of Lirongbao's wife is creased, torn, and dirty.


The colorful silks that are part of the backing,or "frame," for the portraits form an important part of the painting'shistory. When possible, conservators reuse old mounting silks that arein good condition and are appropriate to the painting in terms of colorand age. In these cases, the silk mounting fabric is removed, cleaned,and remounted around the painting.Sometimes the silk is simply worn or damaged beyond repair, as wasthe case with the portrait of Lirongbao's wife. The old mounting silkwas extremely soiled and stained. It is also torn and broken, and largepieces were missing. These silk fabrics had become so weak and brittlethat they no longer support the painting safely. Even after cleaning,they could still have shown signs of wear, fading, and stains. Theconservator and curator decided to remove the old mounting and replaceit with new silk.

配图二: New silks are placed around the painting to help the conservator andcurator select an appropriate combination of colors for the newmounting.


The conservator and curator selected new silkfabrics that are historically accurate and visually harmonize with thepainting. Pattern, color, and the style of the mounting were all takeninto consideration. For example, a bright yellow silk decorated withcertain birds or dragons would be appropriate for an imperial portrait,while a more subdued tan goes well with this portrait of the emperor'smother-in-law. Since the mounting must complement the painting, thesilk is often dyed to soften colors and to make the fabric look olderso it blends with the age of the painting. The fabrics are then linedwith thin Chinese paper, and wheat starch paste is used to adhere thepainting to the mounting. This process takes several weeks to complete.

配图三:The new mounting both highlights the portrait and provides a stable support for displaying the scroll.

Portrait of Lirongbao's Wife (act. late 17th century). China, Qing dynasty, 18th to 19th century. Hanging scroll; ink andcolor on silk; image only, 177.6 x 98.6 cm. Arthur M. Sackler Gallery,Purchase—Smithsonian Collections Acquisition Program, and partial giftof Richard G. Pritzlaff, S1991.129


The new mounting silks were dyed to a shade thatharmonizes with the age, color, and style of this portrait. The newfabrics make a durable yet flexible mounting that both shows thepainting to its best advantage and creates a safe support for thescroll's display and handling.

非常感谢lz的贡献,史密斯基金会的修复过程太有意思了!

云归大漠随舒卷,
门对寒流自古今。
从此静窗闻细韵,
琴声常伴读书人。
