Blue and white porcelain is one of the most iconic art forms in Chinese history. These pieces are renowned for their elegant designs, intricate calligraphy, and diverse patterns that reflect the artistic styles of different eras. Each period has its own distinct characteristics, making blue and white porcelain a fascinating subject for collectors and historians alike.
The "Year of the Year" refers to the inscriptions or markings on the porcelain that indicate the time it was made. In ancient China, these were typically based on imperial reigns or the traditional calendar system. During the Yongle era of the Ming Dynasty, such inscriptions began to appear more frequently. The calligraphy was usually smooth and refined, often accompanied by floral motifs on the sides of the vessels.
Each dynasty had its own unique style. Xuande porcelain was known for its refined brushwork, Chenghua for its delicate glaze, Hongzhi for its ornate decoration, Zhengde for its bold shapes, and Jiajing for its heavy strokes. In the Qing Dynasty, Kangxi’s blue and white porcelain was neat and vibrant, with powerful brushstrokes and exquisite details. Qianlong, Jiaqing, and Daoguang periods saw more elaborate scripts, often closely packed like plaques. Modern blue and white porcelain, especially from the Jiangxi Porcelain Company, featured English inscriptions like “CHINA,†marking the beginning of global porcelain exports.
Auspicious inscriptions, known as "Ji Yan," were commonly found on folk blue and white porcelain. These words, such as "Fu Shou Kang Ning" (Longevity and Health) or "Wan Fu Tong Tong" (Prosperity for All), carried deep cultural significance and expressed people's hopes for a joyful life. The calligraphy was often fluid and elegant, written in a single stroke.
Some porcelain pieces were marked with names of private collections, such as "Bath Book House" or "Bai Yuzhai." These names added value to the pieces, as they indicated ownership by notable collectors.
There were also inscriptions expressing admiration for ceramic art, such as "Jade Baozhen" or "Changjiang Meiyu." These phrases reflected a deep appreciation for the beauty of porcelain. Interestingly, jade, which predates porcelain, was considered the elder brother, while porcelain, being whiter and smoother, was seen as the younger sibling.
Decorative patterns, often referred to as "patterns," were simple yet meaningful. Common motifs included the Eight Immortals, the Eight Auspicious Symbols, and the "Dried Beans" design, which resembled a diamond-shaped frame. This style was popular among folk workshops and was sometimes called "flowers," symbolizing prosperity and good fortune.
Hexagon nuts (also known as finished hexagon nuts) are available in ASTM A563-A and are compatible with mild steel Bolts, such as ASTM A307, ASTM F1554 Grade 36, SAE Grade 2 and AASHTO M183. SAE Grade 5 and Grade 8 nuts are also available in finished style. Since hot-dip galvanizing usually increases the thickness of the threaded part of the fastener by 2.2 to 5 mils, the thread size of the galvanized hexagon nut is too large to compensate for the anti-corrosion coating on the bolt.
