What is Chun glaze?

Chun glaze, also known as "crackle glaze" or "crazed glaze," is a unique type of ceramic glaze prized for its distinctive network of fine cracks on the surface. Originating in China, this technique has been around for centuries, dating back to the Song Dynasty. The cracks form due to controlled stresses in the glaze layer as it cools, creating a webbed pattern that is both visually appealing and functional, as it allows the underlying glaze to peek through, often resulting in an intriguing color play.

To achieve the desired chun glaze effect, potters must master several variables, including the glaze's chemical composition, thickness, and the firing temperature and duration. The slightest miscalculation can ruin the piece, making each successfully cracked piece a testament to the artisan's skill and patience.

In tea culture, chun glaze tea ware, such as teapots and cups, are highly valued for their aesthetic beauty and supposed ability to enhance the tea-drinking experience. It is believed that the cracks in the glaze allow the tea to breathe, improving its flavor and aroma. Whether this is a scientific fact or a romantic notion, there's no denying that chun glaze ceramics add an elegant touch to any tea ceremony.
