Victorian Bluestone has a rich history, embedded in the architecture and streets of Melbourne. Despite the understated beauty of this material, there is a larger issue – the vast amounts of waste material generated from its quarrying.
In collaboration with Ash Allen, we set about exploring the possibility of up-cycling this waste material. During a four month investigation we developed our own process of casting, whereby we melt the material at ~1250 deg Celsius, turning the material back into a lava.
When this material cools, it sets as a denser and stronger form, designed to be a decorative wall light.
Each day, a single bluestone factory in Melbourne can generate over fifteen square meters of bluestone sludge per day, that is taken straight to landfill.
With this new process that Ash and myself developed, we are not only looking to produce designer lights, but to also further investigate where this waste material can be applied to on a larger scale.
The process that Ash and myself developed came about through research of traditional methods of sand casting, mixed with a modern technology of kiln firing.
With each firing, the casting material is completely reusable, and is capable of being upscaled.
