Technical Field

[0001] This invention relates to the field of porcelain technology, specifically to a Jian ware tea bowl with golden hare's fur pattern. Background Technology

[0002] Jian ware, a representative of black porcelain, is hailed as the "black pearl" in the crown of porcelain. It is one of the eight famous porcelains of the Song Dynasty in China, named after Jian'an County in Jianzhou Prefecture during the Song Dynasty. Jian ware possesses a unique beauty compared to other porcelains, and as a representative of black porcelain, it is renowned worldwide for its outstanding artistic level.

[0003] Hare's fur Jian ware is a major type of Jian ware, attracting the attention of numerous consumers and ceramic collectors both domestically and internationally. However, the production process of Jian ware is highly complex. For example, improper selection of firing techniques can significantly negatively impact the final product, often resulting in dull colors, bubbles, patches, poor texture, and other defects, leading to firing failure. With rising appreciation levels and advancements in ceramic technology, the demand for Jian ware with superior color and appearance is increasing. Therefore, how to fire Jian ware with excellent color to enhance its appearance and ultimately improve its artistic and collectible value has become a hot research topic in the contemporary ceramics industry.

[0004] Therefore, there is a need in this field to develop a Jianzhan (a type of glazed tea bowl) with an excellent appearance. Summary of the Invention

[0005] The purpose of this invention is to provide a Jian ware tea bowl with excellent appearance, thereby enhancing its artistic and collectible value.
