OXIDIZED FINISHING - A THREE STAGE PROCESS

OXIDIZING
The general term of “oxidizing” is applied to the chemical coloring of metals. The oldest method, and the one that will produce the largest number of shades ranging from black to light brown, is the use of an alkaline sulfide. These sulfide salts were once known as “liver of sulfur” but now are divided into sodium, potassium, barium, ammonium or polysulfides, (polysulfides in the liquid state being used most generally today). The color obtained is dependant upon the composition of the base metal. The colors produced on cast items seldom match those produced on wrought metals. The polysulfide is applied by dipping or hand application to specified areas. The color is
then “set” with a weak acid solution. This process is generally repeated several times until the desired shade is obtained.

RELIEVING (RUBBING)
Relieving, to obtain a contrast of color, is done with either wet or dry pumice depending on how aggressive the removal of the oxidize has to be. Most of the relief is done by tampico or wire wheel on a scratch brush machine or by hand with a tampico brush or scrub pad. This is then followed by hand rubbing with pumice and finished with a dry brass wheel on the scratch brush. In some cases, the oxidize is relieved by use of a suitable buffing compound and loose muslin buff.

LACQUERING or WAXING
All sulfide colors are susceptible to the action of the atmosphere, especially if warm and moist. Lacquering or waxing of the work helps maintain the finish for an extended period.
