baryta , auch: barium oxide , auch: barium hydroxide

Also known as baryta, it is one of the principal compounds of barium.

More recently, baryta has been used to brighten papers intended for ink-jet printing.

Sulfate of baryta is the chief adulterant used in the manufacture of white lead.

It is a hydrous silicate of alumina and baryta.

The light-sensitive silver halide emulsion is then coated over the baryta layer.

The second layer is the baryta, a white opaque coating made primarily from gelatin and barium sulfate.

It was the bisulphate of baryta."

The term baryta derives from the name of a common barium sulfate-containing mineral, barite.

Barium hydroxide ("baryta") was known to alchemists who produced it by heating barium carbonate.

Its oxide is historically known as baryta but it reacts with water and carbon dioxide and is not found as a mineral.

Its hydroxide was known in pre-modern history as baryta; this substance does not occur as a mineral, but can be prepared by heating barium carbonate.

A thin layer of barium sulfate called baryta is coated as on the surface of most photographic paper to increase the reflectiveness of the image.

A suspension of silver salts in gelatin is coated onto a support such as glass, flexible plastic or film, baryta paper, or resin-coated paper.

Minerals mined in the area are gold, silver, kaolin, quartz, feldspar, baryta, zinc, copper, lead, opal, and fluorite.

The baryta layer has two functions 1) to brighten the image and 2) to prevent chemicals adsorbed on the fibers from infiltrating the gelatin layer.

A gelatin silver print is composed of four layers: paper base, baryta, gelatin binder, and a protective gelatin layer or overcoat.

Davy, by analogy with calcium named "barium" after baryta, with the "-ium" ending signifying a metallic element.

Tints are sometimes added to the baryta to add subtle color to the final print; however most modern papers use optical brighteners to extend the paper's tonal range.

The baryta coating limits the penetration of the emulsion into the fibers of the paper and makes the emulsion more even, resulting in more uniform blacks.

Hydrolysis with baryta, or decomposition by the ferment myrosin, gives glucose, allyl mustard oil and potassium hydrogen sulfate.

Matting agents, textured papers, and thin baryta layers that were not heavily calendered produced a low-gloss and textured appearance.

The alkaline earth metals are named after their oxides, the alkaline earths, whose old-fashioned names were beryllia, magnesia, lime, strontia and baryta.

Uvitic acid, 5-methylisophthalic acid, is obtained by oxidizing mesitylene or by condensing pyroracemic acid with baryta water.

Fiber-based (FB or Baryta) photographic papers consist of a paper base coated with baryta.

This gelatin image layer is only one of the four layers found in a typical gelatin silver print, which typically include the overcoat, image layer, baryta, and paper support.
