Aurora – Handmade Jianzhan Tea Cup with Iridescent Glaze (Tenmoku Bowl)

Texture & Material
A celestial iron canvas kissed by polar light—this matte metallic surface shifts from gunmetal grey to ethereal violet-greens, as if capturing the aurora in stoneware. The satin-textured glaze diffuses light like Arctic ice under midnight sun, its chromatic dance changing with every angle.

The Alchemy of Creation
Base Layer: Iron-titanium glaze (FeO-TiO₂-SiO₂) fired at 1290°C in reduction.
Iridescence: Thin-film interference from nano-scale magnetite (Fe₃O₄) crystals.
Texture: Alumina (Al₂O₃) added to create a controlled matte satin finish.

Perfect Pairings
• Silver Needle white tea
• Sake with ice
• A scoop of ice cream
