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 a 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.
