designer's own words:The concept of this design is inspired by the ancient Greek work κρύσταλλος, which the word crystal is loaned from. Κρύσταλλος had the same meaning as crystal, but at root its means anything congealed by freezing, such as ice. Hence the fumigation block made out of crystal is to reflect and celebrate the 3 states of water. The crystal block is the ice, the fumigate oil is the water and eventually turn into steam. Fumigation helps people to relax after a long hardworking day, enhanced by the candlelight and crystal block, which interact with each other and form spectacular shadow and light.
