Chemical coloring of metals is the process of changing the color of metal surfaces with different chemical solutions. The chemical coloring of metals can be split into three types: electroplating – coating the metal surface with another metal using electrolysis. patination – chemically reacting the metal surface to form a colored oxide or ...
Electrochemical coloring of metals is a process in which the surface color of metal is changed by electrochemical techniques, i.e. cathodic or anodic polarization. The first method of electrochemical coloring of metals are certainly Nobili's colored rings, discovered by Leopoldo Nobili, an Italian physicist in 1826.
This process was repeated until the desired depth of color was achieved or the metal simply did not color further. This is one of the reasons rust and fume bluing are generally more rust-resistant than other methods. The parts are then oiled and allowed to stand overnight. This process leaves a deep blue-black finish. [8]
White color cannot be applied due to the larger molecule size than the pore size of the oxide layer. [23] Alternatively, metal (usually tin) can be electrolytically deposited in the pores of the anodic coating to provide more lightfast colors. Metal dye colors range from pale champagne to black. Bronze shades are commonly used for architectural ...
When buffing there are two types of buffing motions: the cut motion and the color motion. The cut motion is designed to give a uniform, smooth, semi-bright surface finish. This is achieved by moving the workpiece against the rotation of the buffing wheel, while using medium to hard pressure. The color motion gives a clean, bright, shiny surface ...
Cloisonné (French:) is an ancient technique for decorating metalwork objects with colored material held in place or separated by metal strips or wire, normally of gold. In recent centuries, vitreous enamel has been used, but inlays of cut gemstones , glass and other materials were also used during older periods; indeed cloisonné enamel very ...

Once the metal has been rolled into a sheet or bar, several techniques are used to produce a range of effects. Mokume-gane has been used to create many artistic objects. Though the technique was first developed for production of decorative sword fittings, the craft is today mostly used in the production of jewelry and hollowware. [2]
