“…For alchemists, gold was greatly treasured as evidenced by the common quest for the philosopher’s stone ( lapis philosophorum ), an agent that would make possible transmutation of base metals into gold 4, 5 . Furthermore, gold was considered to be indestructible and have immense medicinal value; hence early alchemists set out to produce potable gold, “the elixir of life” 5 .…”

A new way to elaborate coloured carat gold materials has been developed. Instead of using traditional metallurgy route, we built a new 18-K bulk material using nanostructured gold particles. The resulting colour is the consequence of a well-known property of gold nanoparticles: the surface plasmon resonance effect. Depending on the chemical environment around the nanoparticles, their shape and size, it is possible to tune the colour of gold. Thanks to this property, it is possible to obtain a large panel of colours not achievable via conventional alloying route. Here, we focus on one hybrid nanostructured material: Au-SiO 2 . The development of a new synthesis route enables us to obtain nanostructured micrometric powders that can then be pressed to obtain a bulk material. The resulting nanocomposites are characterized by means of energy-dispersive X-ray spectroscopy (EDX), fire assay, TEM and spectrophotocolorimetry. All these characterizations have shown that our composites exhibit a gold content superior to 75 % by weight and have a much more vivid colour than classical coloured gold. The new composites are therefore deeply coloured 18-K materials.

The preparation and application of gold powder have a long history in China. The ancient Chinese had a deep understanding of the morphology and size of naturally occurring gold powder. In the early stages, the technology for making gold powder probably involved grinding gold on a special stone. Later, the technique of making gold powder from gold foil was developed in the second century AD. The amalgamation technique was also invented in the 2nd century AD. In ancient China, gold powder was used for a number of applications, including in medicine and for paint and printing silk and paper etc. The techniques used for the application of gold powder in ancient China were the most advanced in the world at that time.
