Construction paper, commonly referred to as sugar paper, is a type of colored cardstock paper. It is manufactured by applying dyes to cellulose fibers. The most common types are blue construction paper and white construction paper.
Blue construction paper is used for modeling in art classes or craft projects where the color blue is needed. It can also be used for painting on black backgrounds. The blue dye is mixed with water and applied to the paper while it is wet. The color will not run when the paper is dry.
White construction paper is used for creating artwork where the background needs to be white. The white dye is mixed with water and applied to the paper while it is wet. Like blue construction paper, white construction paper can be painted over when dry.
There are many other colors of construction paper available including red, yellow, green, orange, purple, and various shades of blue. These papers are used in similar ways to blue and white construction paper.
Colored paper refers to any paper that is not plain white or simply colored; e.g., colored pencil drawings, paintings, etc.
People often ask me what kind of paint to use for coloring construction paper.
The textbook Manufacture of Pulp and Paper (Brassington 1929) defines construction paper or "poster paper" as a "colored newsprint" that is softly sized and made up of 50–75 percent groundwood and the rest unbleached sulphite pulp. It is used for craft and decorative purposes.
In fact, construction paper is any paper with thin strips of fiberboard or plastic sandwiched between two sheets of paper. The material is used for making models, art projects, and other items. It is available in many colors and styles. The term "construction paper" may also be applied to papers that are not actually made from construction materials; for example, an office pad that is used for drawing on. Such papers are usually less expensive than true construction papers but are still durable enough for most uses.
Construction paper gets its name because you can use it to build things. It's commonly used for craft and art projects where you need lightweight material that's easy to work with. You can find different types of construction paper available at home improvement stores, art supply stores, and online. There is regular old white construction paper as well as colored paper for creating designs of all kinds.
You will often see blue, red, and yellow construction paper. These colors are called primary colors because they are used together to create every other color.
Bamboo pulp paper, bleached for offset printing paper, typing paper, and other sophisticated cultural materials, unbleached for wrapping paper, and so on. The pulp and paper business accounts for a sizable and rising share of the global economy. In 2017, it was estimated that the world production of wood pulp and paper was about 29 billion kilo-tons, with China accounting for nearly one fifth of this quantity.
Bamboo is a grass that grows throughout Asia and some parts of North America. It is believed that bamboo has been used for writing papers since at least A.D. 1. Bamboo leaves are very flexible and can be used to make sheets that can be printed upon with colored inks, used for books, manuscripts, and documents.
The first recorded use of bamboo for papermaking was in Japan during the Heian period (794-1185). By the Muromachi period (1337-1573), bamboo had replaced oak as the main source of timber for papermakers in Japan. Bamboo's advantages as a raw material over oak included its abundance and low cost; it could also be harvested seasonally.
In China, bamboo has been used for writing papers since at least A.D. 1.
A concrete shape composed of hefty paper material. These forms are usually used for molding buildings or other structures before the mold is cast in plaster or another material. The form is removed after it has served its purpose.
What kind of paper can be used to make forms? Any kind of paper can be used as long as it is not too thick or too thin (usually no more than half an inch). Paper that is not strong enough to support themselves will need to be reinforced with fiberglass or plastic wire. Forms can also be made from wood, but they must be painted to prevent the moisture from getting to the ground board.
How do you use forms? First, mark out where each piece is going to go on the form by either cutting around the form or using tape. Make sure there is at least 1/4" gap between pieces. Next, pour a small amount of cement into the form and press the pieces into place. Don't worry about making everything perfect; you will be removing the form soon after it is set up. Let the cement dry completely before moving onto the next step.
The vast majority (about 95 percent) of the raw resources required to create paper, on the other hand, originate from trees. Depending on the intended type of paper, the pulp combination may need to be bleached to produce whiter paper. Papermakers bleach pulp with a range of chemicals to get the desired hue. The bleaching process can also reduce the amount of lignin and cellulose in the pulp, allowing for higher yields when recycling the material.
About 5 percent of paper comes from non-forest sources such as cotton and flax. Some counterfeit bills are now being made from recycled paper because it is so cheap to produce. However, since most papers used in currency are derived from wood, this method does not overcome the problem of deforestation.
After processing, paper products become waste that must be disposed of some how. Disposing of paper products properly is important because they can contain harmful substances such as chlorine from pools or bleach from clothes dryers. Disposing of these materials incorrectly could lead to environmental damage.
Paper comes from trees, therefore it is natural for it to cause concern for the environment. Deforestation, erosion, water pollution, and global warming are just some of the problems associated with paper production. However, these problems can be reduced if more sustainable forestry practices are used during tree harvesting and paper manufacturing processes.
Litmus paper is a form of pH paper that is manufactured by dying the paper with natural lichen colours. Litmus paper is often either red or blue. When the pH is alkaline, red paper turns blue; when the pH is acidic, blue paper turns red. The color change occurs because different chemicals are present in the paper at these two extremes of pH.
When litmus paper is exposed to an acid solution, it becomes colored in the same way as a litmus test. This makes litmus paper useful for checking the acidity of solutions.
Litmus paper is used in laboratory experiments to detect acids because it changes color when acid is added to it. The paper can also be used to check the basicity of solutions by adding bases to it to see if it turns yellow.
Litmus paper was first made in 1816 by Johann Wilhelm Wolf who obtained his colors from the lichens that grew on rocks near his factory in Germany. He sold the paper under the name "Litmus" which means "little stone".
In 1885, Edward Frankland modified the process by using chemical salts instead of natural lichen dyes. This made litmus paper affordable for laboratories worldwide. In 1955, Lee Talley invented plastic litmus paper which is now the standard form sold today.
