Grain Wood

Grain Wood is a product manufactured in a Sawmill. Cut Wood is the material required to make it. It can be used as material for other products.
==History==
The first man who succeeded in extracting wood pulp was the French chemist Anselme Payen. He produced cellulose by breaking coniferous wood down chemically. To do so, Payen used nitric acid to seperate the lignin from the raw material which had been cut into pieces. Lignin is responsible for wood's stability. After this procedure, which took place at a temperature of 125 to 145° C, he washed the pulp and bleached it with chlorine. Soon after this, the substance gained industrial importance as a primary material.\nGrain wood was perfectly suitable for the production of paper, cardboard and viscose fibers. It was also perfect as a filling and insulating material.
==Did You Know That?==
An increasing amount of wrapping material and office equipment is required these days. Therefore, the need for paper and grain wood has been constantly rising. The circular saw has been in use since 1840, especially in the USA. It consumes a relatively high percentage of wood while cutting, though grain wood urgently needed for paper manufacture is left over. Sawmills have been driven by water wheels (turbines) since the early 19th century.
