1. Uvitic acid is obtained by oxidizing mesitylene or by condensing pyruvic acid with baryta water. 2. The second layer is the baryta , a white opaque coating made primarily from gelatin and barium sulfate. 3. Barium hydroxide ( " baryta " ) was known to alchemists, who produced it by heating barium carbonate. 4. Uvitic acid, 5-methylisophthalic acid, is obtained by oxidizing mesitylene or by condensing pyroracemic acid with baryta water. 5. Matting agents, textured papers, and thin baryta layers that were not heavily calendered produced a low-gloss and textured appearance. 6. Davy, by analogy with calcium, named " barium " after baryta , with the "-ium " ending signifying a metallic element. 7. A gelatin silver print is composed of four layers : paper base, baryta , gelatin binder, and a protective gelatin layer or overcoat. 8. The monohydrate ( x = 1 ) is known as baryta , or baryta-water, it is one of the principal compounds of barium. 9. The monohydrate ( x = 1 ) is known as baryta, or baryta -water, it is one of the principal compounds of barium. 10. Oxidized barium was at first called " barote " by Guyton de Morveau, a name that was changed by Antoine Lavoisier to " baryta ."
