Origins and development are often difficult to decipher. The resultant end will often be influenced by man. –Irv CigarBroker
¶Deckle edge is the feathered edge of a page. Traditionally and historically, this was a side effect of the process of making paper. At the semi-liquid stage of paper making, a form called a deckle was used to create the size and shape of the sheet. Some of the paper seeping below the edge of the deckle would form an uneven edge on the outside. When the final sheet was then cut, the outside edges would form the fore edge of the book, leaving a slightly uneven edge. ¶Modern publishers will sometimes use paper that creates that same effect as a decorative device. Contemporary book buyers may at times mistake that uneven page edge for a manufacturing defect, as the page edge looks somewhat like paper that has been ripped, rather than cut, but the effect is intended to be a reference to the history of publishing, and thus is often considered to be aesthetically more refined than uniformly machine-cut edges.(Biblio.com) ¶A deckle is a removable wooden frame or “fence” used in manual papermaking. In a related sense, it can also mean deckle edge paper—a type of paper with rough edges used in the book trade. (Wiki) ¶The irregular, untrimmed edge of the handmade paper, often used for ornamental effect in fine books and stationery, now often produced artificially on machine-made paper. (Dictionary)
¶A microchip is a small piece of semiconductor material carrying many integrated circuits. Note further: The basic component of modern miniaturized electronics. The “chip” is a series of electrical circuits built into a tiny wafer of silicon or another semiconductor. (Note that these circuits may be made by exposing the chip to a high-temperature vapor of controlled composition. The vapor deposits a thin layer (sometimes only a few atoms thick) on the silicon. In this way complex layers of materials, such as those found in transistors can be built up in a very small area. (both Dictionary.com) ¶Microchip or, according to Merriam-Webster Dictionary – an integrated circuit – is a tiny complex of electronic components and their connections that are produced in or on a small slice of material (as silicon).
¶In a commercial glass plant, sand is mixed with waste glass (from recycling collections), soda ash (sodium carbonate), and limestone (calcium carbonate) and heated in a furnace. The soda reduces the sand’s melting point, which helps to save energy during manufacture, but it has an unfortunate drawback: it produces a kind of glass that would dissolve in water! The limestone is added to stop that happening. The end-product is called soda-lime-silica glass. It’s the ordinary glass we can see all around us.¶Once the sand is melted, it is either poured into molds to make bottles, glasses, and other containers or “floated” (poured on top of a big vat of molten tin metal) to make perfectly flat sheets of glass for windows. Unusual glass containers are still sometimes made by “blowing” them. A “gob” (lump) of molten glass is wrapped around an open pipe, which is slowly rotated. Air is blown through the pipe’s open end, causing the glass to blow up like a balloon. With skillful blowing and turning, all kinds of amazing shapes can be made.¶Glass makers use a slightly different process depending on the type of glass they want to make. Usually, other chemicals are added to change the appearance or properties of the finished glass. For example, iron and chromium based chemicals are added to the molten sand to make green-tinted glass. Oven-proof borosilicate glass (widely sold under the trademark PYREX®) is made by adding boron oxide to the molten mixture. Adding lead oxide makes a fine crystal glass that can be cut more easily; highly prized cut lead crystal sparkles with color as it refracts (bends) the light passing through it. Some special types of glass are made by a different manufacturing process. Bulletproof glass is made from a sandwich or laminate of multiple layers of glass and plastic bonded together. Toughened glass used in car windshields is made by cooling molten glass very quickly to make it much harder. Stained (colored) glass is made by adding metallic compounds to glass while it is molten; different metals give the separate segments of glass their different colors. (explainthatstuff.com)
Tobacco leaves are harvested and aged using a process that combines use of heat and shade to reduce sugar and water content without causing the bigger leaves to rot. This first part of the process, called curing, takes between 25 and 45 days and varies substantially based upon climatic conditions as well as the construction of sheds or barns used to store harvested tobacco. The curing process is manipulated based upon the type of tobacco, and the desired color of the leaf. The second part of the process, called fermentation, is carried out under conditions designed to help the leaf dry slowly. Temperature and humidity are controlled to ensure that the leaf continues to ferment, without rotting or disintegrating. This is where the flavor, burning, and aroma characteristics are primarily brought out in the leaf.¶Once the leaves have aged properly, they are sorted for use as filler or wrapper based upon their appearance and overall quality. During this process, the leaves are continually moistened and handled carefully to ensure each leaf is best used according to its individual qualities. The leaf will continue to be baled, inspected, un-baled, re-inspected, and then re-baled again repeatedly as it continues the aging cycle. When the leaf has matured according to the manufacturer’s specifications, it will be used in the production of a cigar.¶Quality cigars are still handmade. An experienced cigar-roller can produce hundreds of very good, nearly identical, cigars per day. The rollers keep the tobacco moist — especially the wrapper — and use specially designed crescent-shaped knives, called chavetas, to form the filler and wrapper leaves quickly and accurately. Once rolled, the cigars are stored in wooden forms as they dry, in which their uncapped ends are cut to a uniform size. From this stage, the cigar is a complete product that can be “laid down” and aged for decades if kept as close to 21 °C (70 °F), and 70% relative humidity, as the environment will allow. Once cigars have been purchased, proper storage is usually accomplished by keeping the cigars in a specialized wooden box, or humidor, where conditions can be carefully controlled for long periods of time. Even if a cigar becomes dry, it can be successfully re-humidified so long as it has not been handled carelessly and done so gradually. The loss of original tobacco oils, however, will greatly affect the taste.¶Some cigars, especially premium brands, use different varieties of tobacco for the filler and the wrapper. Long filler cigars are a far higher quality of cigar, using long leaves throughout. These cigars also use a third variety of tobacco leaf, called a “binder”, between the filler and the outer wrapper. This permits the makers to use more delicate and attractive leaves as a wrapper. These high-quality cigars almost always blend varieties of tobacco. Even Cuban long-filler cigars will combine tobaccos from different parts of the island to incorporate several different flavors. (Wiki)
¶”Development of the embryo begins at Stage 1 when a sperm fertilizes an oocyte and together they form a zygote.”
[England, Marjorie A. Life Before Birth. 2nd ed. England: Mosby-Wolfe, 1996, p.31]
¶“Human development begins after the union of male and female gametes or germ cells during a process known as fertilization (conception).
“Fertilization is a sequence of events that begins with the contact of a sperm (spermatozoon) with a secondary oocyte (ovum) and ends with the fusion of their pronuclei (the haploid nuclei of the sperm and ovum) and the mingling of their chromosomes to form a new cell. This fertilized ovum, known as a zygote, is a large diploid cell that is the beginning, or primordium, of a human being.”
[Moore, Keith L. Essentials of Human Embryology. Toronto: B.C. Decker Inc, 1988, p.2]
