The sound of crackling from Ru ware is a unique experience. The cracks in Ru ware refer to the fine fissures that form in the glaze as it cools due to differences in shrinkage rates. They are commonly known as “ice-crackle” or “crazing” patterns. These cracks not only give Ru ware its distinctive beauty, but under certain conditions, they can also produce a special sound.

This sound results from the minute, ongoing changes in the glaze as it responds to environmental stress caused by temperature fluctuations. The moment the kiln door opens, a clear, resonant yet gentle sound rings out, like crystal, echoing into the distance. The sound of cracks in Ru ware is like the clear chime of wind bells, and also resembles the sound of jade or bamboo instruments, making it truly beautiful.

The sound of the cracks is often bright and melodious, soothing the mind, like a breeze passing through a bamboo grove or drizzle tapping on a window lattice. Ru ware pieces that produce this sound are not only works of visual art, but also offer an auditory pleasure, reflecting the ancients’ meticulous attention to their objects and modern people’s aspirations for a higher quality of life.
