Understanding “Oil Drop”
The term “oil drop” refers to the unique glaze pattern found on Jianzhan Tenmoku bowls, characterized by numerous small spots with a golden or silver metallic luster scattered across the black glaze.
These spots, likened to boiling oil droplets, create a dazzling effect and are the result of the iron content in the glaze interacting with the kiln’s atmosphere during the firing process.
Formation Process of “Oil Drop”
The creation of “oil drop” Jianzhan involves a complex interplay of clay selection, kiln firing, and atmospheric conditions. The iron-rich clay is shaped into bowls and fired at high temperatures. The key to forming “oil drop” patterns lies in the precise control of the kiln’s temperature and atmosphere, which allows the iron oxide in the glaze to form into distinct metallic spots.
Artistic Value of “Oil Drop”
Each “oil drop” Jianzhan is a one-of-a-kind piece of art, with no two bowls being identical. The unpredictability of the glaze patterns adds to their allure and artistic value. Collectors and tea connoisseurs prize these bowls for their unique beauty and the craftsmanship that goes into creating them.
