What Are Colloids? The Physics of Suspended Particles
Tiny particles that neither sink nor dissolve: what defines a true colloidal solution — and why blood, fog and milk share the same physics.
Classic
The Sun Metal
Colloidal Gold
Our centrepiece: true colloidal gold with genuine 50 ppm, deep ruby red, as only true gold particles can be. Crafted by the modified high-voltage plasma process from fine-gold electrodes (99.99%, from a German refinery), by hand and to order.
- Concentration
- up to 50 ppm
- Source Material
- 99.99% purity
- Carrier Medium
- double-distilled water
- Appearance
- Deep ruby red: from 10 ppm a true gold colloid shows pink, at 50 ppm it glows ruby red. Colourless products contain no colloidal gold.
- Made for
- lab work, technical use and plant trials

Real or fake?
The colour betrays the content
True colloidal gold takes on colour as its gold content rises: from colourless through pink to deep ruby red. Move the slider and see what an honest solution has to look like.
50ppm
Mass marketOur gold
Genuine 50 ppm
Deep ruby red: genuine 50 ppm. This is how our plasma gold glows. The colour itself is the proof.
To the pharaohs and high priests of Egypt, gold was the flesh of the gods and the condensed essence of the sun. The alchemists called it Sol.
Worth Knowing
Gold is not formed on Earth: it is born in the collision of neutron stars and once arrived on our planet as cosmic dust.
Thanks to gold nanoparticles, the 4th-century Roman Lycurgus Cup glows green or ruby red depending on where the light falls. As little as 0.01% gold suffices for the intense colour.
All the gold ever mined in the world would together form a cube of only about 20 metres per side.
Today gold works inside pacemakers and insulin pumps, and even pregnancy tests contain gold colloids.
