Lead white paint dries relatively quickly to form a strong, flexible paint film. Lead-based white is one of the oldest manufactured pigments. It was the only white pigment available to artists in appreciable quantities until the twentieth century, when zinc white and titanium white became available. [42]
White lead is the basic lead carbonate 2PbCO 3 ·Pb (OH) 2. [ 1] It is a complex salt, containing both carbonate and hydroxide ions. White lead occurs naturally as a mineral, in which context it is known as hydrocerussite, [ 1] a hydrate of cerussite. [ 2] It was formerly used as an ingredient for lead paint and a cosmetic called Venetian ...
Primer reduces the number of paint coats needed for good coverage and even color. A thin layer of paint may still be permeable to water. Water can permeate into the wood and cause warping, mildew, or dry rot. Primer improves the waterproofing of the finish. [4] Primers are not used as part of a wood stain treatment because they obscure the wood ...
Whitewash. Whitewash, calcimine, kalsomine, calsomine, or lime paint is a type of paint made from slaked lime ( calcium hydroxide, Ca (OH) 2) or chalk ( calcium carbonate, CaCO 3 ), sometimes known as "whiting". Various other additives are sometimes used.
Lead white is a thick, opaque, and heavy white pigment composed primarily of basic lead carbonate, 2PbCO 3 ·Pb(OH) 2, with a crystalline molecular structure. [1]: 67 [2]: 43 It was the most widely produced and used white pigment in different parts of the world from antiquity until the nineteenth century, when it was displaced by zinc white and later by titanium white.
Infobox references. Zinc chromate, Zn Cr O 4, is a chemical compound, a salt containing the chromate anion, appearing as odorless yellow powder or yellow-green crystals, but, when used for coatings, pigments are often added. [ 2][ 3][ 4] It is used industrially in chromate conversion coatings, having been developed by the Ford Motor Company in ...
Primary color. The emission spectra of the three phosphors that define the additive primary colors of a CRT color video display. Other electronic color display technologies ( LCD, Plasma display, OLED) have analogous sets of primaries with different emission spectra. A set of primary colors or primary colours (see spelling differences) consists ...
Zinc white. Johann Georg von Dills, Triva Castle, 1797. An early example of zinc white's use in painting [ 1]: 183. Zinc white is an inorganic pigment composed of zinc oxide that has been used by painters since the late eighteenth century. [ 1] Alongside lead and titanium white, it is among the three most prominent white pigments that are ...
