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.
Media, or mediums, are the core types of material (or related other tools) used by an artist, composer, designer, etc. to create a work of art. [1] For example, a visual artist may broadly use the media of painting or sculpting, which themselves have more specific media within them, such as watercolor paints or marble.
When exposed to air, oils do not undergo an evaporation process like water does. Instead, they dry semisolid by oxidation causing polymerization. The rate of this process can be very slow, depending on the oil. The advantage of the slow-drying quality of oil paint is that an artist can develop a painting gradually.
Red acrylic paint squeezed from a tube Example of acrylics applied over each other. Experimental pictures with "floating" [1] acrylic paint Acrylic paint is a fast-drying paint made of pigment suspended in acrylic polymer emulsion and plasticizers, silicone oils, defoamers, stabilizers, or metal soaps.

Alternately, resin casting may be accomplished with a resin plus a nearly equal amount of a "hardener" liquid (as in many epoxy resin or polyester resin systems), which functionally contains a second polymer, for use in forming a final product plastic which is a copolymer. Copolymers contain two different alternating chemical entities in the ...
Today, epoxy and the acrylic types predominate. The description and the generally touted advantages are as follows: Epoxy: Although aliphatic epoxy materials have been used, the majority of EPD epoxy types are based on aromatic epoxy polymers, most commonly based on polymerization of diglycidal ethers of bis phenol A. The polymer backbone may ...
Lacquer being sprayed onto a cabinet. A coating is a covering that is applied to the surface of an object, or substrate. [1] The purpose of applying the coating may be decorative, functional, or both. [2]
Venus de Milo, at the Louvre. Art history is, briefly, the history of art—or the study of a specific type of objects created in the past. [1]Traditionally, the discipline of art history emphasized painting, drawing, sculpture, architecture, ceramics and decorative arts; yet today, art history examines broader aspects of visual culture, including the various visual and conceptual outcomes ...
