Bath Sponge
A sponge is a cleaning aid made of soft, porous material. Typically used for cleaning impervious surfaces, sponges are especially good at absorbing water and water-based solutions. Originally made from natural sea sponges, they are most commonly made from synthetic materials today. Etymology The word comes from the Ancient Greek term (), which in turn is probably derived from a Mediterranean Pre-Indo European substrate. History The first reference of sponges used for hygiene dates from Ancient Greece. Competitors of the Olympic Games bathed themselves with sea sponges soaked in olive oil or perfume before competing. In the book '' Odyssey'' by the Greek poet Homer, the god Hephaestus cleans his hands, face, and chest with a sea sponge, and the servants in the Odysseus palace also used sea sponges to clean the tables after the meals the suitors of Penelope had there. The Greek philosophers Aristotle and Plato also mentioned sea sponges in both scientific and hist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Xylospongium
The xylospongium or tersorium, also known as ''sponge on a stick'', was a hygienic utensil used by ancient Romans to Anal hygiene, wipe their anus after defecating, consisting of a wooden stick (Ancient Greek, Greek: , ''xylon'') with a sea sponge (Greek: , ''spongos'') fixed at one end. The tersorium was shared by people using public latrines. To clean the Sponge (tool), sponge, they simply washed it in a bucket with water and salt or vinegar. This became a breeding ground for bacteria, causing the spread of disease in the latrine. In classical antiquity a ''xylospongium'' might be used as a toilet brush. In the baths of the seven sages in Ostia (Rome), Ostia, a fresco from the 2nd century contains the Inscription ''(u)taris xylosphongio'' which is the first known mention of the term. Also in the early second century a papyrus letter of Claudius Terentianus to his father Claudius Tiberianus uses the term ''xylespongium'' in a phrase. In the middle of the first century Seneca ...

Wood Fiber
Wood fibres (also spelled wood fibers, see spelling differences) are usually cellulosic elements that are extracted from trees and used to make materials including paper. The end paper product (paper, paperboard, tissue, cardboard, etc.) dictates the species, or species blend, that is best suited to provide the desirable sheet characteristics, and also dictates the required fibre processing (chemical treatment, heat treatment, mechanical "brushing" or refining, etc.). In North America, virgin (non-recycled) wood fibre is primarily extracted from hardwood (deciduous) trees and softwood (coniferous) trees. The wood fibre can be extracted as a primary product, or collected during the milling of lumber. Wood fibres can also be recycled from used paper materials. Paper Wood fibres are treated by combining them with other additives which break down the fibres into a spongy mass called pulp. The pulp is then processed, and the network of tiny fibres is pressed flat, becoming paper. C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nanoplastics
Microplastics are fragments of any type of plastic less than in length, according to the U.S. National Oceanic and Atmospheric Administration (NOAA) and the European Chemicals Agency. They cause pollution by entering natural ecosystems from a variety of sources, including cosmetics, clothing, food packaging, and industrial processes. The term ''macroplastics'' is used to differentiate microplastics from larger plastic waste, such as plastic bottles. Two classifications of microplastics are currently recognized. Primary microplastics include any plastic fragments or particles that are already 5.0 mm in size or less before entering the environment. These include microfibers from clothing, microbeads, and plastic pellets (also known as nurdles). Secondary microplastics arise from the degradation (breakdown) of larger plastic products through natural weathering processes after entering the environment. Such sources of secondary microplastics include water and soda bottles, fis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Scouring Pad
A scouring pad or scourer is a small pad of metal or plastic mesh used for scouring a surface. Some scouring pads have one side made of a soft sponge-like material and the other is the aforementioned mesh. History The scouring pad has been reincarnated in several forms over the years. In 1928, R. B. Kingman patented the scouring ball, which was one of the first scouring pads made of a metal mesh. On 30 September 1941United States patent 2,257,456was issued to Joseph R. Crockford of Chicago, IL for a scouring device of the type employed for "cleansing and scouring pots, pans and other household implements." The invention provided for a "plate of non-corrosive metal, arched or curved to fit the fingers." In 1942, David J. Kelman patented a toroidal metal scouring pad. This was, and still is, used as an abrasive scrubbing pad, however, it is becoming less common, as it removes non-stick surfaces off pans. On June 19, 1962, Alfred Benjamin patented the stainless-steel scouring p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polyurethane Foam
Polyurethane products have many uses. Over three quarters of the global consumption of polyurethane products is in the form of foams, with flexible and rigid types being roughly equal in market size. In both cases, the foam is usually behind other materials: flexible foams are behind upholstery fabrics in commercial and domestic furniture; rigid foams are between metal, or plastic walls/sheets of most refrigerators and freezers, or other surface materials in the case of thermal insulation panels in the construction sector. Its use in garments is growing: for example, in lining the cups of brassieres. Polyurethane is also used for moldings which include door frames, columns, balusters, window headers, pediments, medallions and rosettes. Polyurethane formulations cover an extremely wide range of stiffness, hardness, and densities. These materials include: * Low-density flexible foam used in upholstery, bedding, automotive and truck seating, and novel inorganic plant substrates fo ...

Polyester
Polyester is a category of polymers that contain the ester functional group in every repeat unit of their main chain. As a specific material, it most commonly refers to a type called polyethylene terephthalate (PET). Polyesters include naturally occurring chemicals, such as in plants and insects, as well as synthetics such as polybutyrate. Natural polyesters and a few synthetic ones are biodegradable, but most synthetic polyesters are not. Synthetic polyesters are used extensively in clothing. Polyester fibers are sometimes spun together with natural fibers to produce a cloth with blended properties. Cotton-polyester blends can be strong, wrinkle- and tear-resistant, and reduce shrinking. Synthetic fibers using polyester have high water, wind and environmental resistance compared to plant-derived fibers. They are less Fireproofing, fire-resistant and can melt when ignited. Liquid crystalline polyesters are among the first industrially used liquid crystal polymers. They are use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crucifixion Of Jesus
The crucifixion and death of Jesus occurred in 1st-century Judea, most likely in AD 30 or AD 33. It is described in the four canonical gospels, referred to in the New Testament epistles, attested to by other ancient sources, and considered an established historical event. There is no consensus among historians on the details. Christopher M. Tuckett in ''The Cambridge companion to Jesus'' edited by Markus N. A. Bockmuehl 2001 Cambridge Univ Press pp. 123–124 In the canonical gospels, Jesus is arrested and tried by the Sanhedrin, and then by Pontius Pilate, who sentences him to flagellation and finally crucifixion by the Roman Empire.''The Cradle, the Cross, and the Crown: An Introduction to the New Testament'' by Andreas J. Köstenberger, L. Scott Kellum 2009 pp. 104–108Evans, Craig A. (2001).

Holy Sponge
The Holy Sponge is one of the Instruments of the Passion of Jesus. It was dipped in vinegar (; in some translations sour wine), most likely posca, a regular beverage of Roman soldiers, and offered to Jesus to drink from during the Crucifixion, according to Matthew 27:48, Mark 15:36, and John 19:29. History Jerusalem An object thought to be the Holy Sponge was venerated in Israel, in the Upper Room of the Constantinian basilica, where Sophronius of Jerusalem spoke of it : Rome In the Basilica di San Giovanni in Laterano in Rome, a brown sponge is venerated. Other pieces of sponge are present at the following: * the Basilica di Santa Maria Maggiore * the Basilica di Santa Maria in Trastevere * St. Mary in Campitelli Gerusalemme The Chapel of the Relics at Santa Croce in Gerusalemme houses another sponge: Constantinople and France In the 7th century, Nicetas took part in the conquest of Egypt from Phocas. He was famed for bringing items he claimed were the Holy Sponge and the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jesus Christ
Jesus, likely from he, יֵשׁוּעַ, translit=Yēšūaʿ, label=Hebrew/Aramaic ( AD 30 or 33), also referred to as Jesus Christ or Jesus of Nazareth (among other names and titles), was a first-century Jewish preacher and religious leader; he is the central figure of Christianity, the world's largest religion. Most Christians believe he is the incarnation of God the Son and the awaited Messiah (the Christ) prophesied in the Hebrew Bible. Virtually all modern scholars of antiquity agree that Jesus existed historically. Research into the historical Jesus has yielded some uncertainty on the historical reliability of the Gospels and on how closely the Jesus portrayed in the New Testament reflects the historical Jesus, as the only detailed records of Jesus' life are contained in the Gospels. Jesus was a Galilean Jew who was circumcised, was baptized by John the Baptist, began his own ministry and was often referred to as "rabbi". Jesus debated with fellow Jews on ho ...
