Making Paper from Trees
Making Paper from Trees Forest Service U.S. Department of Agriculture FS-2 MAKING PAPER FROM TREES Paper has been a key factor in the progress of civilization, especially during the past 100 years. Paper is indispensable in our daily life for many purposes. It conveys a fantastic variety and volume of messages and information of all kinds via its use in printing and writing-personal and business letters, newspapers, pamphlets, posters, magazines, mail order catalogs, telephone directories, comic books, school books, novels, etc. It is difficult to imagine the modern world without paper. Paper is used to wrap packages. It is also used to make containers for shipping goods ranging from food and drugs to clothing and machinery. We use it as wrappers or containers for milk, ice cream, bread, butter, meat, fruits, cereals, vegetables, potato chips, and candy; to carry our food and department store purchases home in; for paper towels, cellophane, paper handkerchiefs and sanitary tissues; for our notebooks, coloring books, blotting paper, memo pads, holiday greeting and other “special occasion’’ cards, playing cards, library index cards; for the toy hats, crepe paper decorations, paper napkins, paper cups, plates, spoons, and forks for our parties. Paper is used in building our homes and schools-in the form of roofing paper, and as paperboard- heavy, compressed product made from wood pulp-which is used for walls and partitions, and in such products as furniture. Paper is also used in linerboard, “cardboard,” and similar containers. Wood pulp is the principal fibrous raw material from which paper is made, and over half of the wood cut in this country winds up in some form of paper products. -

The Renaissance Spreads Outside of Italy
5/9/2019 Big Idea The Renaissance Spreads Outside of Italy Essential Question How did the Renaissance spread to the rest of Europe? 1 5/9/2019 Words To Know Renaissance - “rebirth” in French, the Renaissance was a cultural movement in the 14th-17th centuries during which European artists, scientists, and scholars, were inspired by the achievements of the Greeks and Romans. Let’s Set The Stage… As the Renaissance began to grow in Italy, northern Europe was still recovering from the ravages of the Black Death. But by the 1400s, the cities of the north began to enjoy the economic growth—and the wealth—needed to develop their own Renaissance. 2 5/9/2019 The Spread of Wealth Through Trade Trade routes that existed since the Roman Empire were infused by new wealth and products when trade between the Italian city-states and the Ottoman Empire increased. The Spread of Wealth Through Trade As a result, cities like Cologne, Bruges, Paris, London, and Lisbon became centers of trade and banking. Like in Italian cities, trade led to the establishment of a wealthy class of traders and bankers who supported architects and paid for work from artists. 3 5/9/2019 Papermaking By 1300, papermaking and printing technology reached Europe from China and the Middle East. Papermaking Paper making had contributed to golden ages in China and the Middle East, and to the preservation (saving) of Greek and Roman learning that had been “lost” in Europe and preserved (saved) by scholars (students) in the Ottoman Empire. 4 5/9/2019 The Earliest Books The earliest books were written on scrolls. -

Four Great Inventions of China Many of the Greatest Inventions in Human History Were First Made in China
History Topic of the Month Four Great Inventions of China Many of the greatest inventions in human history were first made in China. By the 13th century, China was an innovative and exciting place to live. Travellers from Europe discovered things there that were beyond imagination in Europe. When the explorer Marco Polo arrived in China, he encountered a Contributer: © Patrick Guenette / 123rf country vastly different from his home of Venice. In his book, The Travels of Marco Polo, Polo describes cities Cai Lun (AD c.57 – 121), was a Chinese courtier official. He is believed to with broad, straight and clean streets (very different from his be the inventor of paper and the home in Venice) where even the poorest people could wash papermaking process, discovering in great bath houses at least three time a week (again very techniques that created paper as we different from hygiene in Europe). would recognise it today. China celebrates four particular innovations as “the Four Great Inventions” — they were even featured as a part of the opening ceremony for the 2008 Beijing Olympic Games. So, what were these four great inventions? Writing it all down: Paper The first of the great inventions was something we all use almost every day: paper. Many different materials had been used for writing things down, like bamboo, wood (both hard to store and write on) or silk and cloth (much more expensive). Types of paper have been found in archaeological records dating back thousands of years, but it was very difficult to make. It wasn’t until AD c.105 that a quick and easy way of making paper was invented. -

The Fine Art Trade Guild Standards for Mountboard (Mat Board) and Other Boards Used in Framing
The Fine Art Trade Guild Standards for Mountboard (Mat Board) and other boards used in framing. Amended 10th June 2004 Copyright C Sumner, Fine Art Trade Guild Introduction These standards are directed to the composition, combinations, and characteristics of papers and paper-boards used in the framing of artwork, keepsakes and memorabilia. They help to give material categorisation of these to fit into the five levels of framing specified by the Fine Art Trade Guild. The objective of each level of framing is stated, with examples of the kinds of things for which that level is suitable. At present, all board that does not meet either the Cotton Museum Board standard or the Conservation Board standard will be deemed to be Standard Board and suitable for Commended, Budget and Minimum levels of framing only. The specifications for Standard Board may be further refined in due course as the quality of boards in this category vary greatly. Conservation Board is deemed to be acceptable for all levels except Museum level framing. Museum Board is deemed to be acceptable for all levels of framing. It is a prerequisite that the type of surface and texture must be specified relating to any board purporting to meet Guild Standards. If the surface is designed to accept decoration and embellishments, as in the case of Mountboard unless otherwise stipulated, it should be fit for the purpose. (FACTS Institute, USA, Test No. 6-97). International – Note that in some markets no distinction is made between Museum and Conservation Framing. In others, the terminology is reversed, i.e.
