The Mummy

The test is performed at atmospheric venues, located outdoors on the roof of a building or on the ground. Types of pigments. The most widely used inorganic pigments, they are divided into natural and artificial. Natural relatively few, they are extracted from the earth and in its natural form ready for consumption. They are inferior to the artificial brightness and color, but cheap, harmless and very resistant to weathering. Natural mineral pigments. Chalk – white powder. Consists mainly of calcium carbonate (CCO3).

It is used in water based paints and putty. The Mummy – red, with brown tint pigment. Is an aluminosilicate, colored with iron oxides. Applies to all forms of communication. Minium iron – brownish-red color, represents a floured into a fine powder and iron ore in the main mass consists of iron oxide (78 – 85%). Different light – and atmosferotoykostyu. Ochre – yellow pigment, consisting of clay, painted 10-25% solution of Fe2O3.

Cheap and durable pigment. Umbra – brown, green-tinged color, contains 50% iron oxide and MnO. Siena – temnozhelty, the composition of aluminosilicate containing 45-70% iron oxide. Burnt Sienna has a brown color. Cinnabar – mercury sulphide. It occurs as the mineral red. Bauxite (from white to red) consists mainly of aluminum hydroxide. Characterized by a high weather resistance, lightfastness and covering power. Pyrolusite (black to steel-gray) consists of peroxide of manganese. Water used for production of dye formulations. Graphite – dark gray mineral consisting of carbon. Used to cover oryachih metal surfaces. Synthetic mineral pigments. White pigments. Zinc white – to represent the composition of zinc oxide with small amounts of impurities. These white apply for both domestic and for exterior. They have good light – and weather. Spreading rate – no more than 100-110 g / sq.m., Koeffetsient reflection – 99.7%. Lithopone white – a fine powder – a product of deposition from a solution mixture of ZnSO4 and BSO4.
