Paint decorative white

The oil is extracted from the seed by expelling and solvent extraction. Cold pressed oil, light yellow in colour, is used for edible purposes without refining. The oil is a semi-drying oil and is also used in artists paints, in white paint in conjunction with boiled poppy seed oil and in soap after hydrogenation. Poppy seeds are used for decorating baked goods and as bird seed. 

Each painter had his own technique the binding medium was thus prepared using different additives, giving rise to a variety of recipes for each technique. For example, it is believed that fig latex (a white liquid exuded by the fig tree) was commonly added to the egg tempera, and that animal or plant resins were added to oil- and wax-based binders. On account of their adhesive properties, these materials were used not only as paint binders, but also as consolidants in restorations, as ingredients in varnishes used to finish paintings, and as ingredients of mordants to apply metallic leaf decorations. 

The ancient Egyptians were adept at creating water paints, which were used to decorate the interiors of their pyramids, temples, and palaces. Much like the cave painters paints, their colors were earth tones—yellow ochre, sienna, red, black, and white—but two new colors were added blue and green. Later, between A.D. 117 and 161, the early Christians in Egypt made paints of pigment particles suspended in hot beeswax. Their works, called encaustic paintings, are still well preserved and brilliant in color. In the eighth century, the Phoenicians obtained a vibrant purple dye from a particular kind of oyster. 

Figure 51 shows a nineteenth-century Japanese fan (in black and white rather than the actual color) decorated with a watercolor painting of the phoenix. The figure bears a striking resemblance to a twentieth-century cultural icon—Rodan, the subject of a modern Japanese film genre that 1 will dub Plos-tique Monstresque. Indeed, Rodan rises from the ashes of nuclear tests to menace the earth and teach us all a good lesson. It is a phoenix born on the funeral pyre of the atomic bomb. 

The main disadvantage of phenolic resins is their intrinsic yellow to brown color. As a result they cannot be used for colored and white paints. They can only be used for decorative coatings in a few cases (e.g., gold lacquers). Phenolic resins have favourable mechanical properties and a high chemical resistance. Paint systems that are optimally adjusted to the requirement profile can be developed by suitable formulations. 

The main application technique in the decorative area is still by hand (brush). Hence, future trends continue to reflect attention on worker exposure and environmental issues. This is already seen in the move to low aromatic content white spirits and isoparaffin solvents in conventional systems. High solids and waterborne technologies are being developed and both possess certain advantages and disadvantages, mainly relating to appearance and ease of use. Water-based systems bring, in principle, increased potential for water pollution, as consumers continue to rinse their brushes and paint rollers under the tap and transfer the water-soluble components such as amines and biocides to the aqueous environment. The consequence of diffuse water emissions of this type is still under debate.
