The renowned Japanese architect drew his inspiration from a technique for preserving construction timber by charring its surface, known in Japan as Shou-Sugi-Ban or Yakisugi. This ancient technique uses charring wood as means to preserve it without the need of painting or sealing, an aspect leading to the current revival of this technique in eco-friendly architecture. Adapting this process to the centuries-old glass craft technique enabled a contemporary design that is unique for every single piece of hand-blown glass.
