Paper

Paper is a thin sheet of matted cellulose fibers. Largely derived from lignocellulose, paper is created from a pulp dissolved into a slurry that is drained and dried into sheets. Different types of paper are defined by constituent fiber, paper pulp, sizing, coating, paper size, paper density and grammage.

While any object, such as a stone, can serve as a paperweight, decorative paperweights of metal, glass, jade or other material are also produced, either by individual artisans or factories.

Invented in 1844 by Charles Fenerty of Nova Scotia, Canada, it usually has an off white cast and distinctive feel. It is designed for use in printing presses that employ a long web of paper (web offset, letterpress and flexographic), rather than individual sheets of paper.

paper size

Grammage and basis weight, in the pulp and paper industry, are measures of the area density of a paper product, that is, its mass per unit of area. Two common ways of expressing the area density of a paper product are used: Expressed in grams (g) per square metre (g/m2), regardless of its thickness (caliper) (known as grammage). This is the measure used in most parts of the world. It is often notated as gsm on paper product labels and spec sheets. Expressed in terms of the mass per number of sheets of a specific paper size (known as basis weight). The convention used in the United States and

Filigranology is the study of watermarks. It is usually pursued in order to discover information about the date and origin for a paper-based piece of writing or a piece of art. There are several catalogues of watermarks – most notably C. M. Briquet's, Les Filigranes (1907), which dealt mainly with the period up to 1600, and Edward Heawood's Watermarks, Mainly of the 17th and 18th Centuries (1950), both of which include illustrations of many watermarks from dated documents. These catalogues form an important resource for researchers.
