namely‚ pigments (titanium dioxide‚ zinc oxide etc.)‚ solvents (mineral turpentine) and resins and additives. Pigments are finely ground solids of different shades to give colour‚ durability‚ consistency and other properties to paint. It is also one of the major raw materials‚ accounting for one-third of the total raw materials cost. Amongst the vital pigments used in the process of paint manufacture is Titanium dioxide (TiO2) and the industry consumes around 60% of TiO2. This pigment is available

Case study Red pigment samples were collected from the early Christian necropolis of El-Bagawt at Kharga Oasis‚ Egypt. El-Bagawat necropolis is dating back to the 4th century AD. Two of the most outstanding and best preserved of the decorated chapels are named ‘Chapel

High electrons are carried from one molecule to another by electron carriers. Also there is a another carrier called NADP+ (Nicotinamide Adenine Dinucleotide Phosphate)‚ it turns into NADPH when it holds two high energy electrons with a hydrogen

Encyclopædia Britannica Paper chromatography is used to separate "dissolved chemical substances". An example of dissolved chemical substances could be the pigments that make up a specific color‚ for example in a marker. When a chromatography paper experiment is done on a black marker‚ the experiment tends to separate all the different pigments that make up the color. In this experiment‚ the substance investigated was a black water soluble Giotto marker pen. Paper chromatography has two phases

While researching the Pompeian styles of wall painting‚ I discovered how incredible the Second Pompeian style truly is. There are four Pompeian styles of wall paintings‚ which have been divided based upon the fundamental differences in the way the artist treated the wall and created space. The first two styles began during the Republican period‚ and were derived from Greek wall paintings. The First Pompeian style in the second century B.C. was common in many homes. This style was a simple way of
