Longquan Kiln products are known for their classic simplicity and dignified forms, adorned with an elegant glaze. Ge Kiln ware, in particular, features a thin yet durable body and a richly layered glaze that displays an intricate, ever-varying network of crackle patterns.

The clay composition used in Longquan celadon is especially critical, containing a high proportion of quartz along with minerals such as kaolinite and mica.

With origins dating back 1,700 years, Longquan Celadon flourished during the Northern Song Dynasty and peaked in the Southern Song. It is recognized as one of China's "Five Great Kilns" of classical ceramics.

How are the "Golden Threads and Iron Lines" of Ge Kiln formed?

The differing thermal expansion coefficients of the ceramic body and the glaze layer cause the glaze to crack during the cooling phase after firing, resulting in an intricate network of cracks of varying sizes. Initially, these cracks are colorless. However, Ge Kiln ware typically undergoes a specialized process where, in the later stages of firing, the pieces are immersed in an iron-rich solution or cooled in an iron-ion-enriched environment. The iron ions penetrate the cracks, oxidize upon exposure to air, and form iron oxides, creating the dark brown or black patterns known as "Iron Lines."

The "Golden Threads" develop later. After the ware is removed from the kiln, over years or even decades of use and storage, fine cracks gradually accumulate dust, moisture, and other impurities from the air. These substances slowly oxidize and age, eventually forming the golden-brown patterns known as "Golden Threads."
