Tobikanna, also called chattering, is a traditional Japanese decorative technique used to create unique textures and patterns on the surface of ceramic pieces during throwing. This technique involves the use of a metal tool with spikes, which scrapes the surface of the clay as the piece is throwed on the pottery wheel, generating a texture of crisscrossing lines or irregular patterns that add depth and character to the piece.
The marks left by the tobikanna are not only visually appealing, but also add a tactile texture that enriches the sensory experience of the piece. In addition to its decorative function, tobikanna can enhance the adhesion of the glaze to the surface of the clay by creating micro-textures that facilitate the attachment of the glaze coating.
Interesting Fact
The tobikanna technique is common in Japanese ceramics from the Shigaraki region, famous for its utilitarian pieces decorated with simple yet elegant patterns. Shigaraki is one of six ancient schools of Japanese ceramics and is known for its focus on texture and naturalness, where tobikanna plays a key role in creating distinctive surfaces.
Helpful Tip
Practice the tobikanna technique with different types of tools to vary the thickness and depth of the lines you leave on the pieces. Experiment with different throwing speeds and applied pressures to discover how these factors affect the final pattern and texture.
