Introduction

Natural Timber Task 1; Hard Woods Ash (Oak Stain) An oak is a tree or shrub in the genus Quercus of which about 400 species exist. The genus is native to the northern hemisphere, and includes deciduous and evergreen species extending from cold latitudes to tropical Asia and the Americas. Oaks have spirally arranged leaves, with a lobed margin in many species; some have serrated leaves or entire leaves with a smooth margin. The flowers are catkins, for being evergreen, but are not actually a distinct group and instead dispersed across the genus. Oak wood has a density of about 0.75 g/cm�, great strength and hardness, and is very resistant to insect and fungal attack because of its high tannin content. It also has very attractive grain markingsproduced in spring. The fruit is a nut called an acorn, borne in a cup-like structure known as cupules. ...read more.

The flowers are produced in loose inflorescences when the tree is leafless, each flower about 5 mm diameter, with five yellowish petals. The fruit is a pendulous capsule about 10 cm long and 4 cm broad; when mature it splits into five sections to release the 15-20 seeds. Soft Woods Pitch Pine The Pitch Pine is a small-to-medium sized tree, which grows irregularly. This pine occasionally hybridizes with other pine species such as Loblolly Pine. The Pitch Pine is found mainly in the northeastern United States, from Maine and Ohio to Kentucky and northern Georgia. This pine occupies a variety of habitats from dry, acidic sandy uplands to swampy lowlands, and can survive in very poor conditions; it is the primary tree of the New Jersey Pine Barrens. The needles are in fascicles of three, about 6-13 cm in length, and are stout (over 1 mm broad) ...read more.

Conclusion

Part 2 This Wooden Box Was Made Out Of Ash Wood. This Bench Was Made Out Of Pine Wood. This Table Was Made Out Of Sapele Wood. This Table Was Made Out Of Pitch Pine Wood. This Table Was Made Out Of Sitka Spruce Wood. Task 3 Tree Rings Tree-ring is the method of scientific dating based on the analysis of tree-ring growth patterns. This technique was developed during the first half of the 20th century originally by the astronomer A. E. Douglass, the founder of the Laboratory of Tree-Ring Research at the University of Arizona. Growth rings also referred to as tree rings or annual rings, can be seen in a horizontal cross section cut through the trunk of a tree. The inner portion of a growth ring is formed early in the growing season, when growth is comparatively rapid and is known as "early wood" or "spring wood" or "late-spring wood". The outer portion is the "late wood, often being produced in the summer, though sometimes in the autumn and is denser. ...read more.

Many of them are copolymers, i.e., polymers consisting of more than one monomer making a compound.

    From about 8000BC humans in the middle-east, crafted locally found gold and copper to make decorative items. By about 4000BC they had learned how to smelt copper from ore. Around 2000BC it was found that another soft metal, tin, could be added to copper to produce an alloy which possessed some of the features of both parent metals.
