What Is Xuan Paper? China's Thousand-Year Handmade Paper

Xuan paper is a handmade paper produced in and around Jing County (泾县), Anhui Province, in eastern China, made from the bark of the blue sandalwood tree and rice straw. Known in Chinese as xuanzhi (宣纸), it has been the preferred surface for Chinese calligraphy and ink painting for over a thousand years, and it is the paper behind the paintings and brushwork that collectors most value today. If Chinese painting has a canvas, Xuan paper is it.

The answer to what makes Xuan paper special is a matter of decades, not just quality. A well-made sheet of Xuan paper can survive for centuries without yellowing or turning brittle, which is why it is the standard choice for restoring and reproducing ancient Chinese works. Chinese painters call it the "king of papers," a title earned by the one property that no machine-made paper has fully matched: it absorbs ink beautifully, holds it exactly where the brush puts it, and lasts.

The Materials: Bark and Straw

Xuan paper begins with two humble ingredients. The first is the bark of the blue sandalwood tree (Pteroceltis tatarinowii), known in Chinese as qingtan (青檀), a small tree native to the mountains around Jing County. The second is rice straw, harvested from local paddies after the grain is collected.

Neither ingredient is remarkable on its own. What matters is the combination. The bark fibers give the sheet its strength and its famous resistance to aging, while the rice straw fills the sheet out, giving it the soft, even texture that lets a brush glide. Papers made from bark alone are too tough; papers made from straw alone are too fragile. The blend of the two, in proportions kept secret by each workshop, is the heart of the craft. The blue sandalwood trees grow on the rocky hillsides around Jing County, and workshops have tended the same groves for generations; the bark is harvested in strips rather than by felling the tree, so the same tree yields its fiber for decades.

A Process Measured in Months

Making Xuan paper is one of the slowest production processes in the paper world. The bark is harvested, stripped, and soaked; the straw is cleaned and steamed; and both are left to ferment and age before the fibers are beaten to a pulp. From start to finish, the process involves more than one hundred steps, and a single batch can take up to two years — including a period of natural aging in the open air that no machine has managed to rush.

The forming itself is done by hand, sheet by sheet. The papermaker dips a bamboo screen into a vat of fiber slurry and lifts it with a precise rocking motion, letting the fibers settle in overlapping layers. Skilled makers judge the sheet by feel and light, and a finished batch is pressed, dried on heated walls, and inspected one sheet at a time. The vat worker, called the "paper doctor" in the trade, must keep the slurry uniform, the screen level, and the rhythm of the dipping steady; a single uneven lift shows up as a thin patch in the finished sheet. This is why genuine Xuan paper is expensive: it is the product of months of waiting and two skilled hands.

The Three Grades of Xuan Paper

Xuan paper is sold in three grades, and choosing between them is the single most important decision for a painter or calligrapher:

• Raw Xuan (sheng, 生) — untreated, highly absorbent. Ink spreads softly into the fibers the moment the brush touches down, producing the blurred, organic edges prized in freehand ink painting.
• Ripe Xuan (shu, 熟) — treated with alum sizing, which closes the pores of the paper. Ink sits on the surface instead of soaking in, allowing crisp lines and fine detail, ideal for meticulous brushwork.
• Semi-raw Xuan (banshu, 半熟) — a middle ground between the two. It absorbs some ink but holds a firmer line, a forgiving choice for beginners and for painters who want controlled washes.

Beginners usually start with semi-raw, move to raw as they learn to trust the brush, and reserve ripe paper for detailed work. There is no best grade, only the right grade for the technique.

What Xuan Paper Does to Ink

When ink meets Xuan paper, something particular happens. The brush carries water and pigment to the surface, and the sheet draws both into its fibers at a controlled rate — quickly enough that the stroke does not sit on top of the paper, slowly enough that the line holds its shape. On raw Xuan, the ink spreads at the edges in soft, feathered halos, an effect painters have built entire styles around. On ripe Xuan, the sized surface holds the ink crisp, which is why fine-lined flower-and-bird painting is done on it. This behavior is not a property of paper in general; it is the result of the bark-and-straw blend and the unhurried, sheet-by-sheet forming. Machine-made papers absorb unevenly or too fast, which is why a painting that looks effortless on Xuan can look muddy on anything else.

Why UNESCO Honored It

In 2009, UNESCO added the traditional craft of making Xuan paper to its list of Intangible Cultural Heritage. The recognition was for the entire ecosystem of the craft: the trees and paddies of Jing County, the workshops with their century-old vats and screens, and the knowledge carried by the makers. No other paper in China received the same honor. Today the craft is officially protected, and the workshops of Jing County display the heritage designation with pride.

The listing also confirmed what restorers already knew. When museums repair a thousand-year-old scroll, they do not reach for modern paper; they commission Xuan paper made in the traditional way, because only paper made this slowly can match the aging behavior of the original.

Choosing Your First Xuan Paper

If you are new to ink painting or calligraphy, here is a practical starting path:

• Start with semi-raw Xuan for practice — it forgives mistakes and works with most brushes and inks.
• Buy from a sheet, not a roll, until you know what you like; sheets are easier to compare and store flat.
• Check the texture with your fingertips — genuine Xuan feels soft and slightly rough, never slick or waxy.
• Keep unused sheets flat and dry, away from sunlight and damp walls.
• Keep a sample of each grade in your sketchbook — the fastest way to learn the difference is to compare strokes side by side on the same day.

The Paper That Carries a Culture

Xuan paper is more than a supply. It is the surface on which Chinese painting defined itself — the paper that makes a brushstroke bloom, a wash breathe, and a scroll last a thousand years. Learning to paint on Xuan is learning to paint with the material, not just on it.

If you are ready to begin, our Xuan paper collection offers all three grades in a range of sizes, from practice sheets to museum-grade rolls, with plain and lined formats for calligraphy. The paper that has carried Chinese art for a millennium is waiting for your first stroke.
