A chemically derived product that rusts metal instantly upon contacting the surface of a metal and which can be easily and safely used by ornamental metal craftpersons. The chemically derived product is a liquid compound that contains the following constituents: (a) 93.0% by weight of water; (b) up to 5.0% by weight of a copper salt, the copper salt being selected from a copper salt group consisting of copper sulfate, copper nitrate, and copper chloride; and (c) a remaining amount consisting of an acid compound selected from an acid compound group consisting of sulfamic acid, oxalic acid, hydrochloric acid and nitric acid. The liquid compound can be particularly formulated for oxidizing steel or copper and may be produced having a predetermined coloring dye constituent selected from a color dye group consisting of copper, auburn, or gold, if oxidizing steel, or a color dye selected from a color dye group consisting of patina, aqua blue, or green, if oxidizing copper.

Process for producing an ornamental rust finish on a ferrous metal

An electrochemical process and system for dehalogenating halogenated hydrocarbons. The process facilitates on-site processing and transformation of waste oils, PCB oils in electrical transformers and chlorinated solvents to salts. The system includes a two-piece tubular structure including an electrical insulating member, an electrode member having perforations leading into a hollow vessel portion. The process includes, by example, reacting the halogenated hydrocarbon compound with at least one metal hydroxide selected from a metallic hydroxide group consisting of sodium hydroxide, calcium hydroxide, zinc hydroxide, and potassium hydroxide in the presence of an alcohol selected from an alcohol group consisting of methanol, ethanol, or isopropanol. The tubular structure is inserted into the container and energized by applying a voltage to the electrode member. The electrochemical reaction results in producing an electrolyte salt solution containing metallic cations and halogen anions which migrate into the hollow vessel portion where the migrated halogen ions are trapped. Upon completion of the reaction, the probe with the trapped halogen is removed from the container and the trapped halogen disposed. The process is repeated until the concentration level of halogen is at, or below, a predetermined acceptable concentrations level. The process has particular utility for on-site treatment of hazardous waste material in 55 gallon drums and facilitates recycling of existing stored hazardous material.
