Greasepaint
Foundation is a liquid, cream, or powder makeup applied to the face and neck to create an even, uniform color to the complexion, cover flaws and sometimes change the natural skin tone. Some foundations also function as a moisturizer, sunscreen, astringent or base layer for more complex cosmetics. Foundation applied to the body is generally referred to as "body painting" or "body makeup". History The use of cosmetics to enhance complexion reaches back into antiquity. "Face painting" is mentioned in the Old Testament (Ezekiel 23:40). Ancient Egyptians used foundation. In 200 BC, ancient Greek women applied white lead powder and chalk to lighten their skin. It was considered fashionable for Greek women to have a pale complexion. Roman women also favoured a pale complexion. Wealthy Romans favoured white lead paste, which could lead to disfigurement and death. Men also wore makeup to lighten their skin tone, using white lead powder, chalk, and creams. The cream was made from animal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Elizabethan Era
The Elizabethan era is the epoch in the Tudor period of the history of England during the reign of Queen Elizabeth I (1558–1603). Historians often depict it as the golden age in English history. The Roman symbol of Britannia (a female personification of Great Britain) was revived in 1572, and often thereafter, to mark the Elizabethan age as a renaissance that inspired national pride through classical ideals, international expansion, and naval triumph over Spain. This "golden age" represented the apogee of the English Renaissance and saw the flowering of poetry, music, and literature. The era is most famous for its theatre, as William Shakespeare and many others composed plays that broke free of England's past style of theatre. It was an age of exploration and expansion abroad, while back at home, the Protestant Reformation became more acceptable to the people, most certainly after the Spanish Armada was repelled. It was also the end of the period when England was a sep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zinc White
Zinc white is an inorganic pigment composed of zinc oxide that has been used by painters since the late eighteenth century. Alongside lead and titanium white, it is among the three most prominent white pigments that are commercially available today. Its primary advantages are its low toxicity (particularly in contrast with lead white) and the cool clarity of its color. It was initially developed in the 1780s by the French chemist and magistrate Louis-Bernard Guyton de Morveau, who struggled to popularize its use. The French Academy of Sciences approved of the invention in 1782, but artists from the French Royal Academy of Painting and Sculpture expressed skepticism. Initially, zinc white pigment was more costly to produce than lead white, but its price diminished as production methods improved over the course of the nineteenth century. While the superior safety of zinc white had been established by the end of the eighteenth century, manufacturers of lead white downplayed these d ...

Edwardian Era
In the United Kingdom, the Edwardian era was a period in the early 20th century that spanned the reign of King Edward VII from 1901 to 1910. It is commonly extended to the start of the First World War in 1914, during the early reign of King George V. The era is dated from the death of Queen Victoria in January 1901, which marked the end of the Victorian era. Her son and successor, Edward VII, was already the leader of a fashionable elite that set a style influenced by the art and fashions of continental Europe. Samuel Hynes described the Edwardian era as a "leisurely time when women wore picture hats and did not vote, when the rich were not ashamed to live conspicuously, and the sun never set on the British flag." The Liberals returned to power in 1906 and made significant reforms. Below the upper class, the era was marked by significant shifts in politics among sections of society that had largely been excluded from power, such as labourers, servants, and the industri ...

Iodine
Iodine is a chemical element; it has symbol I and atomic number 53. The heaviest of the stable halogens, it exists at standard conditions as a semi-lustrous, non-metallic solid that melts to form a deep violet liquid at , and boils to a violet gas at . The element was discovered by the French chemist Bernard Courtois in 1811 and was named two years later by Joseph Louis Gay-Lussac, after the Ancient Greek , meaning 'violet'. Iodine occurs in many oxidation states, including iodide (I−), iodate (), and the various periodate anions. As the heaviest essential mineral nutrient, iodine is required for the synthesis of thyroid hormones. Iodine deficiency affects about two billion people and is the leading preventable cause of intellectual disabilities. The dominant producers of iodine today are Chile and Japan. Due to its high atomic number and ease of attachment to organic compounds, it has also found favour as a non-toxic radiocontrast material. Because of the spec ...

Chalk
Chalk is a soft, white, porous, sedimentary carbonate rock. It is a form of limestone composed of the mineral calcite and originally formed deep under the sea by the compression of microscopic plankton that had settled to the sea floor. Chalk is common throughout Western Europe, where deposits underlie parts of France, and steep cliffs are often seen where they meet the sea in places such as the Dover cliffs on the Kent coast of the English Channel. Chalk is mined for use in industry, such as for quicklime, bricks and builder's putty, and in agriculture, for raising pH in soils with high acidity. It is also used for " blackboard chalk" for writing and drawing on various types of surfaces, although these can also be manufactured from other carbonate-based minerals, or gypsum. Description Chalk is a fine-textured, earthy type of limestone distinguished by its light colour, softness, and high porosity. It is composed mostly of tiny fragments of the calcite shells or sk ...

Acids
An acid is a molecule or ion capable of either donating a proton (i.e. hydrogen cation, H+), known as a Brønsted–Lowry acid, or forming a covalent bond with an electron pair, known as a Lewis acid. The first category of acids are the proton donors, or Brønsted–Lowry acids. In the special case of aqueous solutions, proton donors form the hydronium ion H3O+ and are known as Arrhenius acids. Brønsted and Lowry generalized the Arrhenius theory to include non-aqueous solvents. A Brønsted–Lowry or Arrhenius acid usually contains a hydrogen atom bonded to a chemical structure that is still energetically favorable after loss of H+. Aqueous Arrhenius acids have characteristic properties that provide a practical description of an acid. Acids form aqueous solutions with a sour taste, can turn blue litmus red, and react with bases and certain metals (like calcium) to form salts. The word ''acid'' is derived from the Latin , meaning 'sour'. An aqueous solution of an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nitrate Of Silver
Silver nitrate is an inorganic compound with chemical formula . It is a versatile precursor to many other silver compounds, such as those used in photography. It is far less sensitive to light than the halides. It was once called ''lunar caustic'' because silver was called ''luna'' by ancient alchemists who associated silver with the moon. In solid silver nitrate, the silver ions are three- coordinated in a trigonal planar arrangement. Synthesis and structure Albertus Magnus, in the 13th century, documented the ability of nitric acid to separate gold and silver by dissolving the silver. Indeed silver nitrate can be prepared by dissolving silver in nitric acid followed by evaporation of the solution. The stoichiometry of the reaction depends upon the concentration of nitric acid used. :3 Ag + 4 HNO3 (cold and diluted) → 3 AgNO3 + 2 H2O + NO :Ag + 2 HNO3 (hot and concentrated) → AgNO3 + H2O + NO2 The structure of silver nitrate has been examined by X-ray crystallography seve ...

Mercury (element)
Mercury is a chemical element; it has Symbol (chemistry), symbol Hg and atomic number 80. It is commonly known as quicksilver. A Heavy metal element, heavy, silvery d-block element, mercury is the only metallic element that is known to be liquid at standard temperature and pressure; the only other element that is liquid under these conditions is the halogen bromine, though metals such as caesium, gallium, and rubidium melt just above room temperature. Mercury occurs in deposits throughout the world mostly as cinnabar (mercuric sulfide). The red pigment vermilion is obtained by Mill (grinding), grinding natural cinnabar or synthetic mercuric sulfide. Exposure to mercury and mercury-containing organic compounds is toxic to the nervous system, immune system and kidneys of humans and other animals; mercury poisoning can result from exposure to water-soluble forms of mercury (such as mercuric chloride or methylmercury) either directly or through mechanisms of biomagnification. Mercu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zinc Oxide
Zinc oxide is an inorganic compound with the Chemical formula, formula . It is a white powder which is insoluble in water. ZnO is used as an additive in numerous materials and products including cosmetics, Zinc metabolism, food supplements, rubbers, plastics, ceramics, glass, cement, lubricants, paints, sunscreens, ointments, adhesives, sealants, pigments, foods, batteries, ferrites, fire retardants, semi conductors, and first-aid tapes. Although it occurs naturally as the mineral zincite, most zinc oxide is produced synthetically. History Early humans probably used zinc compounds in processed and unprocessed forms, as paint or medicinal ointment; however, their composition is uncertain. The use of ''pushpanjan'', probably zinc oxide, as a salve for eyes and open wounds is mentioned in the Indian medical text the Charaka Samhita, thought to date from 500 BC or before. Zinc oxide ointment is also mentioned by the Greek physician Dioscorides (1st century AD). Galen suggested treatin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Queen Victoria
Victoria (Alexandrina Victoria; 24 May 1819 – 22 January 1901) was Queen of the United Kingdom of Great Britain and Ireland from 20 June 1837 until Death and state funeral of Queen Victoria, her death in January 1901. Her reign of 63 years and 216 days, which was List of monarchs in Britain by length of reign, longer than those of any of her predecessors, constituted the Victorian era. It was a period of industrial, political, scientific, and military change within the United Kingdom of Great Britain and Ireland, United Kingdom, and was marked by a great expansion of the British Empire. In 1876, the British parliament voted to grant her the additional title of Empress of India. Victoria was the daughter of Prince Edward, Duke of Kent and Strathearn (the fourth son of King George III), and Princess Victoria of Saxe-Coburg-Saalfeld.

Victorian Era
In the history of the United Kingdom and the British Empire, the Victorian era was the reign of Queen Victoria, from 20 June 1837 until her death on 22 January 1901. Slightly different definitions are sometimes used. The era followed the Georgian era and preceded the Edwardian era, and its later half overlaps with the first part of the ''Belle Époque'' era of continental Europe. Various liberalising political reforms took place in the UK, including expanding the electoral franchise. The Great Famine (Ireland), Great Famine caused mass death in Ireland early in the period. The British Empire had relatively peaceful relations with the other great powers. It participated in various military conflicts mainly against minor powers. The British Empire expanded during this period and was the predominant power in the world. Victorian society valued a high standard of personal conduct across all sections of society. The Victorian morality, emphasis on morality gave impetus to soc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
