HEAVY BODY ACRYLIC IRIDESCENT COLORS: GOLDEN Iridescent Acrylics are one of the most unique products available to artists today. They offer highly reflective metallic variations when mixed with GOLDEN colors. The GOLDEN Iridescent colors achieve their reflective properties by synthetically reproducing several natural phenomena - the nacreous, or pearlescent, qualities found in fish scales or the dust of a butterfly's wing, and the shiny and reflective qualities found in certain metals and minerals.
'Coarse' Iridescent colors are simply larger particle size versions of Golden's 'Fine' Iridescent products. Coarse colors in the Iridescent line include Copper, Copper Light, Gold and Pearl. All of Golden's Iridescent colors produce a luster quality by themselves, or when mixed with other colors and mediums. The GOLDEN line of Iridescents can be separated into 3 groups based on chemical composition.
Group I: These colors are derived from mica platelets. They are then coated with an extremely thin layer of titanium dioxide. Refraction and reflection of light at the titanium dioxide layers produces various colors and pearlescent effects. Group 1 pigments include Iridescent Pearl (Coarse and Fine).
Group II: These colors are also derived from mica platelets, but an iron oxide coating causes Group II pigments to possess hues in addition to pearlescent qualities. This group includes Iridescent Gold (Coarse and Fine), Iridescent Copper and Copper Light (Coarse and Fine), and Iridescent Bronze.
Group III: A third group consists of reflective colorants that do not fit the above descriptions, including highly metallic pigments. This group includes Stainless Steel (Coarse and Fine), Micaceous Iron Oxide, and Mica Flakes (all varieties).
Golden Heavy Body Acrylics are Golden's original line of acrylics, known for an exceptionally smooth, thick consistency. It contains the largest assortment available to the professional artist of unique pure pigments in a 100% acrylic emulsion. These colors offer excellent permanency and lightfastness. There are no fillers, extenders, pacifiers, toners or dyes added.
Each color is formulated differently depending on the nature of the pigment. Colors that tolerate higher pigment 'loads' dry to a more opaque, matte finish. Colors that are more reactive and do not accept high pigment loading dry to a glossy finish and tend to be more transparent.
The 'CP' ahead of the name of cadmium colors stands for 'chemically pure'.
