Seal Paper: A Traditional Paper with Modern Uses
Seal paper, also known as xuan paper, is a traditional papermaking material that has its origins in Han dynasty China over 2000 years ago. Made from the bark of the mulberry tree, seal paper has evolved from its initial ceremonial uses to becoming a versatile paper for art, calligraphy and everyday stationery in modern times.

Origins and Early Uses
The earliest form of seal paper can be traced back to the Western Han dynasty between 206 BC to AD 24. Developed as a durable paper for stamp seals, calligraphy brushes and official documents, seal paper was prized for its thickness, texture and ability to withstand daily use without tearing. Being denser and less absorbent than regular writing paper, seal paper allowed delicate strokes of ink to remain vivid without bleeding.

Only the imperial courts and government officials had access to Seal Paper during early Chinese history. It became a status symbol, showing the rank and authority of its owner. Documents written on seal paper carried significant weight. Traditional papermaking techniques like pounding bark, soaking, pounding, pressing, drying and polishing were used to create its distinctive creamy white color and smooth yet textured surface.

Evolution of Production Methods
As papermaking technology advanced, new production methods streamlined the creation of seal paper. By the Song dynasty (960-1279 AD), mechanical pulp beaters replaced manual pounding. Water-powered mills took over the soaking, beating and pressing stages. However, the final polishing and finishing still required skilled artisans.

Modern machines have further industrialized seal paper manufacturing while maintaining quality. The mulberry bark is now processed into wood pulp through pulping, bleaching and refining. State-of-the-art papermaking machines form uniform sheets that are finished by calendaring for a silky feel. Some artisanal seal paper still undergoes traditional polishing.
