Ruyao, the top of the Five Great Kilns of the Song Dynasty, is renowned worldwide for its unique sky-blue glaze and “ Cicada Wing ” crackle. Ruyao Tea ware is not only a vessel for tea but also a precious work of art. However, maintaining Ruyao tea ware is a delicate art that requires careful attention to keep it fresh over time and reveal its unique charm.
The crackle is the most distinctive feature of Ruyao tea ware and one of its most aesthetically pleasing elements. The crackle refers to the naturally occurring fine cracks on the surface of the glaze, light and lively like a cicada's wing. The formation of Ruyao crackle primarily depends on the difference in expansion coefficients between the body and glaze. During high-temperature firing, the glaze contracts faster than the body, forming a dense network of cracks.
Maintaining the crackle of Ruyao tea ware is essentially a subtle interaction process between the tea Infusion and the glaze surface. The minerals and pigments in the tea gradually seep into the cracks, gradually changing their color and texture, making them richer and deeper. Therefore, the key to maintaining Ruyao tea ware lies in regular use and care according to different types of tea.
Care Methods for Crackled Ruyao Tea Ware
- Inaugurating New Ware: For new Ruyao tea ware, it is recommended to soak it in clear water for 24 hours to remove impurities from the clay. Afterward, you can rinse it several times with boiling water to eliminate any residual heat. Once the piece has cooled completely, it is ready for use.
- Daily Maintenance:
- Dedicated Tea, Dedicated Ware: It is suggested to use each piece of Ruyao tea ware exclusively for one type of tea, such as Green Tea, Oolong Tea, or dark tea. Different teas have varying pigments and components, and mixed use may result in uneven coloring of the cracks.
- Nourishing with Tea Infusion: Avoid cleaning the tea ware immediately after brewing. Allow the remaining tea to dry naturally. The minerals and pigments in the tea will gradually permeate the cracks, making them more lustrous and lively.
- Cleaning and Preservation: After use, rinse the tea ware with warm water to remove residue and stains. Avoid using detergents or steel wool, which could damage the glaze.
- Storage Environment: Store Ruyao tea ware in a dry, well-ventilated environment away from direct sunlight and dampness.

- Avoid Oil Stains: Keep Ruyao tea ware away from oil stains, which could affect the color of the cracks.
Maintaining Ruyao tea ware is not just about caring for an artwork; it is also a process of appreciating life and cultivating sentiment. Over time, Ruyao tea ware will gradually develop a unique personal style, becoming your most intimate tea companion.
