The color blooms easily, if you like blooms the color is an asset, if you do not like blooms you may want to avoid iron blue which very easily causes these patterns. Prussian blue (also known as Berlin blue, Brandenburg blue or, in painting, Parisian or Paris blue) is a dark blue pigment produced by oxidation of ferrous ferrocyanide salts. Unfortunately, iron blue loses a lot of intensity when it dries, both in value and color, it becomes grayer when it is dry. The variation is great between different manufacturers, some manufacturers have fairly durable iron blue while it fades faster in others. The color is not fully lightfast in full tone, as diluted it fades even faster. Transparent glasses are tinted with the silica-based cobalt pigment smalt. It is extremely stable and historically has been used as a coloring agent in ceramics (especially Chinese porcelain ), jewelry, and paint. The purity of the color also varies, from greyish blue to intense deep blue. Cobalt blue is lighter and less intense than the (iron-cyanide based) pigment Prussian blue. It is extremely stable and historically has been used as a. The color tone varies quite a bit depending on the manufacturer. Cobalt blue is lighter and less intense than the (iron-cyanide based) pigment Prussian blue. Iron blue is a dye with great variety, in its most concentrated form the color appears deep blackish, almost warm reddish, while well diluted the color is cold greenish, a condition that the experienced painter can benefit from. Antwerp blue is one such example, the dye iron blue and an addition of alumina (or barium sulphate, zinc oxide) create a paler variant, often with poorer durability. through dilution, the pigment could appear as completely different colors, which also gave rise to a lot of other names. Many other names also occur, especially as the dye manufacturers quickly discovered that Iron Blue was a dye that was very well suited for manipulation in various ways, e.g. In printing, the name Milori blue is common. Later, Diesbach moved to Paris where he started a major production of the pigment, hence the name Parisian blue as the paint is sometimes called, especially in oil paint. The prussian blue and cobalt oxide films have been synthesized via a simple galvanostatic method to achieve better film quality to be used in a device. Following the tradition of our Finest Quality lines, the Tri-Art Watercolours contain only the finest artist grade pigments that are signature to Tri-Arts. Iron blue or Prussian blue is a very old synthetic pigment, it was invented in 1704, by chance, by Heinrich Diesbach who was active in Berlin which was in then Prussia, therefore the color is often called Prussian blue or Berliner blue.
