"Pure titanium, Five Elements design, Venice Biennale pedigree — a thermos made to pass down."

The Shanwaishan Heritage Thermos is the flagship piece of the Mountains Beyond Mountains collection, first exhibited at the China National Pavilion of the 14th Venice Architecture Biennale in 2014. Its body is decorated with a landscape pattern inspired by the Chinese Five Elements concept of Wood — symbolizing life, growth, benevolence, and harmony. The name Heritage Thermos is literal: this is a vessel designed to be used daily and handed down through generations.

THE CRAFT

Pure titanium. Natural color. Zero coatings.

Five Elements Design

Five Elements Design

The landscape pattern draws from the Chinese Five Elements concept of Wood — symbolizing life, growth, and benevolence. Each thermos carries centuries of philosophical tradition.

Natural Crystallization Color

Natural Crystallization Color

The thermos's color is achieved through high-temperature crystallization — a purely physical process. No chemical spray, no painted coating. What you see is the natural expression of titanium under controlled heat.
