No two kan-nyuu patterns are identical, nor are any two of Claudia Caviezel's Craquelé tiles. A prized feature of Japanese kan-nyuu ceramics, craquelé is equally prized by Caviezel. Ceramics shrink after firing. If the glaze shrinks faster than the clay it fractures into a craquelé pattern.

Caviezel hurries as she paints inks into selected cracks, otherwise ink seeps into all cracks. Ink-free cracks give her tiles the potential of kan-nyuu tea cups where tea seeps into the craquelé and stains it. As the cup's colour changes it becomes a beloved friend, a relationship Caviezel desires between her tiles and their owners.
