In the case of titanium, niobium, and stainless steel, the colour formed is dependent on the thickness of the oxide (which is determined by the anodizing voltage). Chemically coloring a metal is distinct from simply coating it using a method such as gilding or mercury silvering , because chemical coloring involves a chemical reaction, whereas ...
Transition metal compounds are often colored because of transitions of electrons between d-orbitals of different energy. (see Transition metal#Colored compounds ). Organic compounds tend to be colored when there is extensive conjugation , causing the energy gap between the HOMO and LUMO to decrease, bringing the absorption band from the UV to ...
Titanium is a chemical element; it has symbol Ti and atomic number 22. Found in nature only as an oxide, it can be reduced to produce a lustrous transition metal with ...
Differential tempering is a method of providing different amounts of temper to different parts of the steel. The method is often used in bladesmithing, for making knives and swords, to provide a very hard edge while softening the spine or center of the blade. This increased the toughness while maintaining a very hard, sharp, impact-resistant ...
Glass containing two or more phases with different refractive indices shows coloring based on the Tyndall effect and explained by the Mie theory, if the dimensions of the phases are similar or larger than the wavelength of visible light. The scattered light is blue and violet as seen in the image, while the transmitted light is yellow and red.
Different flames can be tried to verify the accuracy of the color. Wooden splints, Nichrome wires , platinum wires, magnesia rods, cotton swabs, and melamine foam are suggested for support. [ 6 ] [ 7 ] [ 8 ] Safety precautions are crucial due to the flammability and toxicity of some substances involved.

On metal, patina is a coating of various chemical compounds such as oxides, carbonates, sulfides, or sulfates formed on the surface during exposure to atmospheric elements (oxygen, rain, acid rain, carbon dioxide, sulfur-bearing compounds). [2]
