Decoupage or découpage ( / ˌdeɪkuːˈpɑːʒ /; [ 1] French: [dekupaʒ]) is the art of decorating an object by gluing colored paper cutouts onto it in combination with special paint effects, gold leaf, and other decorative elements. Commonly, an object like a small box or an item of furniture is covered by cutouts from magazines or from ...
In physical chemistry and engineering, passivation is coating a material so that it becomes "passive", that is, less readily affected or corroded by the environment. . Passivation involves creation of an outer layer of shield material that is applied as a microcoating, created by chemical reaction with the base material, or allowed to build by spontaneous oxidation
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 salt.
The sparkle effect referred to above has its origin in the optimized thickness of all layers in the pigment structure, including the Al 2 O 3 substrate. Analytical investigations show that the thickness range of the aluminum oxide platelets and the resultant pigments can be controlled very precisely. Special effects
Water acts as a type of binding agent that allows the pigment to merge with the plaster, and once the plaster sets the painting becomes an integral part of the wall. Materials (chemical make-up) Lime cycle. Fresco chemicals consist of the following: Silicon dioxide (sand) Calcium oxide (quick lime) Dihydrogen oxide (water)
Lake pigment. A lake pigment is a pigment made by precipitating a dye with an inert binder, or mordant, usually a metallic salt. Unlike vermilion, ultramarine, and other pigments made from ground minerals, lake pigments are organic. [ 1] Manufacturers and suppliers to artists and industry frequently omit the lake designation in the name.
The imprinted image turned out to be wash-resistant, impervious to temperatures of 250 °C (482 °F) and was undamaged by exposure to a range of harsh chemicals, including bisulphite which, without the gelatine, would normally have degraded ferric oxide to the compound ferrous oxide. [129] Instead of painting, it has been suggested that the bas ...
Epoxy is the family of basic components or cured end products of epoxy resins. Epoxy resins, also known as polyepoxides, are a class of reactive prepolymers and polymers which contain epoxide groups. The epoxide functional group is also collectively called epoxy. [ 1] The IUPAC name for an epoxide group is an oxirane .
