Taboos of calligraphy and painting collection

Taboos for Collecting Calligraphy and Paintings:

When collecting calligraphy and paintings, it's crucial to be aware of several important factors that can affect the preservation and longevity of these precious cultural artifacts. First and foremost, avoid any form of pollution. This includes oil stains, sweat, tea marks, and dust. Dust, in particular, can absorb acidic substances and mold spores, which can lead to acidification and mold growth on the paper, ultimately damaging the artwork.

Second, protect your collection from mildew. Mold, especially black, yellow, red, or purple varieties, is not only unsightly but extremely difficult to remove once it has taken hold. The presence of such mold can permanently harm the surface of the painting or scroll.

Third, keep away from pests like insects, moths, and other small creatures that can chew through delicate paper and silk. These pests can cause irreversible damage, making the piece less valuable or even unusable.

Fourth, avoid direct exposure to light, particularly ultraviolet (UV) light. Prolonged exposure to UV rays can cause paper to yellow, weaken its structure, and make it more fragile over time.

Fifth, ensure proper humidity control. Excessive moisture can cause paper to absorb water, leading to mold, rot, and deterioration. In addition to natural causes, human-related damage—such as fires, wars, and accidents—has also led to the loss of many priceless ancient scrolls and documents.

Proper preservation of paper-based cultural relics is a complex task. Improper handling or storage can significantly reduce the value and integrity of your collection. Historically, collectors used high-quality materials to protect their works. For example, ancient paintings were often stored in fine silk covers, with layers of wood and fabric designed to prevent contamination and provide structural support.

It's also important to maintain cleanliness when handling these items. Always wear gloves to avoid transferring oils, sweat, or dust from your hands onto the artwork. Keep a safe distance—about 1.5 meters—when speaking near the pieces to avoid saliva splashes.

During autumn, it's a good idea to take out your paintings and let them air out, allowing any absorbed moisture to evaporate. However, modern furniture often contains high levels of formaldehyde, which is harmful to both people and artworks. Therefore, it’s best to avoid storing valuable paper artifacts in modern cabinets.

In regions with high humidity, such as southern China during the rainy season, the risk of mold and insect infestation increases. At this time, it's advisable to use desiccants, insecticides, and anti-mold agents to protect your collection.

Traditional Chinese papermaking is a meticulous manual process involving steps like crushing, soaking, boiling, pulping, and drying. Unlike modern mass-produced paper, which often contains chemical additives that weaken the paper over time, traditional handmade paper is free from such chemicals. This makes it more durable and better suited for long-term preservation. As a result, ancient papers are far less prone to degradation compared to many modern reproductions.
