Viton is generally compatible with hydrocarbons, but incompatible with ketones such as acetone, and organic acids such as acetic acid. O-rings made of Viton are typically color-coded as black, but new gaskets, seals and O-rings should be green FKM or black FKM, but with a green mark on the outer edge.iton fluoroelastomers are categorized under the ASTM D1418 and ISO 1629 designation of FKM.

There are also minerals which form both by inorganic and organic processes. For example, calcite (CaCO 3) is a common vein mineral in rocks, and also a shell-forming material in many life forms.Calcite of organic origin conforms to the above definition except for the requirement that it be inorganic.inerals are the building blocks of rocks. Geologists define a mineral as: This excludes man-made substances (e.g. synthetic diamonds), organic substances (e.g. chitin), and substances without a fixed composition which are classified as mineraloids (e.g. volcanic glass [obsidian]).
