Known as the most expensive metal after gold and silver, tin is very malleable and flexible. Though having nearly the whiteness of silver, it does not rust easily nor will air tarnish it readily. It is significantly antibacterial, and also known as a material with low allergic reactivity and high heat conductivity. The product is manufactured using traditional casting techniques which have been passed down through generations for over 400 years in Takaoka. The saucer is made of tin, while the brass cubic incense stand is left uncoloured to enjoy change in colour of the metal over the years.
