| Résumé : |
The history of metal pigments for inks and coatings dates back to the old days of the goldbeater's handcraft several hundred years ago.
The oversize of the gold leafs was finely dispersed in warnishes and used for paintings and all kinds of graphic arts.
The alchemists of the middle ages failed in the search for a chemical synthesis of real gold. It have been the craftsmen who found a way to imitate gold: they took a thin foil of a copperzinc-alloy (Tombak) and treated it like the real gold in a beating process and developed the "imitation gold" besides the genuine gold leaf.
Also here, the oversize was disintegrated and finely dispersed into the first "gold bronze pigments".
A similar way took the development of the "silver bronze" by using aluminum instead of genuine silver in the beating process.
During the last century, both technologies - gold beating and manufacturing of metal pigments - underwent a fast development from the handcraft in the early days to industrialized and more or less fully computerized production process.
The industrialization of metal pigments started with the so called stamping process, where the metal particles have been beatin in mechanically rising and falling hammers (up to 36 stamps per units)
This technology (still in use for some special products for non pigment applications) was soon substituted by ball milling processes in the early 20th century.
In our days gold bronze pigments are produced in dry milling processes, followed by classification and polishing processes according to the requirements of the final application. |
