Conservation And Restoration Of Waterlogged Wood
The conservation and restoration of waterlogged wood is the process undertaken by conservator-restorers of caring for and maintaining waterlogged Conservation and restoration of wooden artifacts, wooden artefacts to preserve their form, and the information they contain. It covers the processes that can be taken by conservators, archaeologists, and other museum professionals to conserve waterlogged wood. This practice includes understanding the composition and agents of deterioration of waterlogged wood, as well as the preventive conservation and interventive conservation measures that can be taken. History Waterlogged wood is a wooden object that has been submerged or partially submerged in water and has affected the original intended purpose or look of the object. Waterlogged wood objects can also include wood found within moist soil from archaeological sites, underwater archaeology, maritime debris, or damaged wood objects. Conservation of waterlogged wood has changed througho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conservator-restorer
A conservator-restorer is a professional responsible for the Conservation-restoration of cultural heritage, preservation of artistic and cultural artifacts, also known as cultural heritage. Conservators possess the expertise to preserve cultural heritage in a way that retains the integrity of the object, building or site, including its historical significance, context and aesthetic or visual aspects.Defining the Conservator: Essential Competencies. (2003). Retrieved from http://www.conservation-us.org/docs/default-source/governance/defining-the-conservator-essential-competencies.pdf. This kind of preservation is done by analyzing and assessing the condition of cultural property, understanding processes and evidence of deterioration, planning collections care or site management strategies that prevent damage, carrying out conservation treatments, and conducting research.Careers in Conservation.

Sublimation (phase Transition)
Sublimation is the Phase transition, transition of a substance directly from the solid to the gas state, without passing through the liquid state. The verb form of sublimation is ''sublime'', or less preferably, ''sublimate''. ''Sublimate'' also refers to the product obtained by sublimation. The point at which sublimation occurs rapidly (for further details, see #False correspondence with vaporization, below) is called critical sublimation point, or simply sublimation point. Notable examples include sublimation of dry ice at room temperature and atmospheric pressure, and that of solid iodine with heating. The reverse process of sublimation is deposition (phase transition), ''deposition'' (also called ''desublimation''), in which a substance passes directly from a gas to a solid phase, without passing through the liquid state. Technically, all solids may sublime, though most sublime at extremely low rates that are hardly detectable under usual conditions. At standard condi ...

Conservation And Restoration Of Cultural Heritage
conservation and restoration of cultural property focuses on protection and care of cultural property (tangible cultural heritage), including artworks, architecture, archaeology, and museum collections. Conservation activities include preventive conservation, examination, documentation, research, treatment, and education. This field is closely allied with conservation science, curators and registrars. Definition Conservation of cultural property involves protection and restoration using "any methods that prove effective in keeping that property in as close to its original condition as possible for as long as possible." Conservation of cultural heritage is often associated with art collections and museums and involves collection care and management through tracking, examination, documentation, exhibition, storage, preventive conservation, and restoration. The scope has widened from art conservation, involving protection and care of artwork and architecture, to conservat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wood Preservation
Wood preservation refers to any method or process, or even technique, used to protect the wood and extend its service life. Most wood species are susceptible to both biological (''biotic'') and non-biological (''abiotic'') factors that cause decay and/or deterioration. Only a limited number of wood species possess natural durability, and even those may not be suitable for all environments. In general, wood benefits from appropriate preservation measures. In addition to structural design considerations, a variety of chemical preservatives and treatment processes — commonly known as timber treatment, lumber treatment, pressure treatment or modification treatment — are used to enhance the durability of wood and wood-based products, including engineered wood. These treatments may involve physical, chemical, thermal, and/or biological methodology aimed at protecting wood from degradation. They increase its resistance to biological agents such as fungi, termites, and insects, as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bremen Cog
The Bremen cog is a well-preserved wreck of a cog dated to 1380, found in 1962 in Bremen. Today, it is displayed at the German Maritime Museum in Bremerhaven as one of the main features. Three nearly identical replicas of this cog have been built: ''Ubena von Bremen'', ''Hansekogge'', and ''Roland von Bremen''. The discovery On 8 October 1962, wooden fragments of a ship were found in the Weser River during dredging operations. They turned out to be remnants of a cog that seems to have sunk during a storm flood after drifting away from a shipyard before completion. Until then, cogs had mostly been known from medieval documents and seals; there was only one earlier find in the Noordoostpolder (the Netherlands). Based on the dendrochronological analysis of the oak timber from which the cog was built, the ship was dated to about 1380 AD. Salvage and reconstruction The large parts were measured, registered, and stored in water basins in a pier shed in Bremen to prevent the wood ...

Mary Rose
The ''Mary Rose'' was a carrack in the English Tudor navy of Henry VIII of England, King Henry VIII. She was launched in 1511 and served for 34 years in several wars against France, Scotland, and Brittany. After being substantially rebuilt in 1536, she saw her last action on 1545. She led the attack on the galleys of a French invasion fleet, but sank off Spithead in the Solent, the strait north of the Isle of Wight. The wreck of the ''Mary Rose'' was located in 1971 and was raised on 11 October 1982 by the Mary Rose Trust in one of the most complex and expensive maritime salvage projects in history. The surviving section of the ship and thousands of recovered artefacts are of great value as a Tudor period time capsule. The excavation and raising of the ''Mary Rose'' was a milestone in the field of maritime archaeology, comparable in complexity and cost to the raising of the 17th-century Swedish warship ''Vasa (ship), Vasa'' in 1961. The ''Mary Rose'' site is designated under ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vasa (ship)
''Vasa'' (previously ''Wasa'') () is a Swedish warship built between 1626 and 1628. The ship sank after sailing roughly into her maiden voyage on 10 August 1628. She fell into obscurity after most of her valuable bronze cannons were salvaged in the 17th century, until she was located again in the late 1950s in a busy shipping area in Stockholm harbor. The ship was salvaged with a largely intact hull in 1961. She was housed in a temporary museum called Wasavarvet ("The Vasa Shipyard") until 1988 and then moved permanently to the Vasa Museum in the Royal National City Park in Stockholm. Between her recovery in 1961 and the beginning of 2025, ''Vasa'' has been seen by over 45 million visitors. The ship was built on the orders of the King of Sweden Gustavus Adolphus as part of the military expansion he initiated in a war with Polish–Lithuanian Commonwealth, Poland-Lithuania (1621–1629). She was constructed at the navy yard in Stockholm under a contract with private entreprene ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Freeze Drying
Freeze drying, also known as lyophilization or cryodesiccation, is a low temperature dehydration process that involves freezing the product and lowering pressure, thereby removing the ice by sublimation. This is in contrast to dehydration by most conventional methods that evaporate water using heat. Because of the low temperature used in processing, the rehydrated product retains many of its original qualities. When solid objects like strawberries are freeze dried the original shape of the product is maintained. If the product to be dried is a liquid, as often seen in pharmaceutical applications, the properties of the final product are optimized by the combination of excipients (i.e., inactive ingredients). Primary applications of freeze drying include biological (e.g., bacteria and yeasts), biomedical (e.g., surgical transplants), food processing (e.g., coffee), and preservation. History The Inca were freeze drying potatoes into chuño since the 13th century. The process ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conservation And Restoration Of Wooden Artifacts
The conservation and restoration of wooden artifacts refers to the preservation of art and artifacts made of wood. Conservation and restoration in regards to cultural heritage is completed by a conservator-restorer. See also Conservation and restoration of wooden furniture Nature of the material Wood is a vascular material that comes from the trunk, roots, or stems of over 3,000 varieties of plants. It is a cellular tissue and therefore can be understood by looking into the biological structure. Cell structure Wood is porous and its growth is directional. This is due to the cellular structure of the material. Cellular structure determines factors such as grain, texture, and color. Identification of wood types is undertaken by a conservation scientist. Grain Wood grain is created by the variations in number and arrangement of cells. It specifically refers to the longitudinal alignment of cells, or the direction in which the fibers are going. The six types of grain are: straight, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polyethylene Glycol
Polyethylene glycol (PEG; ) is a polyether compound derived from petroleum with many applications, from industrial manufacturing to medicine. PEG is also known as polyethylene oxide (PEO) or polyoxyethylene (POE), depending on its molecular weight. The structure of PEG is commonly expressed as H−(O−CH2−CH2)n−OH. PEG is commonly incorporated into hydrogels which present a functional form for further use. Uses Medical uses * Pharmaceutical-grade PEG is used as an excipient in many pharmaceutical products, in oral, topical, and parenteral dosage forms. * PEG is the basis of a number of laxatives (as ''MiraLax, RestoraLAX, MoviPrep, etc.''). Whole bowel irrigation with polyethylene glycol and added electrolytes is used for bowel preparation before surgery or colonoscopy or for children with constipation. Macrogol (with brand names such as Laxido, Movicol and Miralax) is the generic name for polyethylene glycol used as a laxative. The name may be followed by a number th ...
