Casting Ancient Bronze in a Modern Light


Casting Ancient Bronze in a Modern Light

February 11, 2013

In the world of Ochre, the iterative process of designing and making is as beautiful as the end product itself; especially in the magical Seed Cloud chandelier, where the process used to cast hundreds of bronze stems comes from another age with a technique that can be dated back at least 5,000 years.

Intrigued by the courses they had taken in traditional craft techniques in art school, Harriet Maxwell Macdonald and Joanna Bibby founded Ochre, their home furnishings brand with shops in New York and London, and set about reinterpreting their lessons in modern ways. The ancient and evocative Lost-Wax casting process beckoned as they searched for a technique to realize their nature-inspired designs. “Few people have any idea of the research and craftsmanship that go into the production of this particular design,” New York-based Maxwell Macdonald says. “We decided to make a series of workshop images in order for our clients to feel closer to the process, and also understand the complexity and skill that go into these beautiful pieces.”
