Where was the first billiards table made?
A core phenolic center is made that is not of high tolerance. Then, at least 2 additional layers are built up over the core, each of better tolerance. In most cases, only the outer layer has the color and design. The exact material, method and number of layers varies from type to type. There is a reason one set may cost $160 and another only $60, and it generally is assocaited with the effort and tolerance.

What is the resale value of pool balls not made of Bakelite?
Unless the balls are made of ivory used pool balls have very little value. Balls go out of round as a result of normal play, and therefore a new set of cheaply made $30 balls is almost certainly superior for play than set that has had a lot of use. Ivory pool balls have sold for more than $200 apiece. If the pool balls are not collectible, such as ivory, they have little collectible value.
What do poachers use elephant tusk for?
Elephant ivory (as well as the ivory of other animals) has been used as a medium for artists for thousands of years. Some of the most intricate carving has come out of the East, and specimens in museums today might cost tens or even hundreds of thousands of dollars to purchase if they were for sale. The tusks continue to be displayed as a whole in a number of places. Ivory was also adapted for use to create billiard balls and to put on piano keys. It has always been used to make chop sticks, the handles of many items (like knives and guns), combs, brooches and other jewelry, and was inlaid in many, many different things. Use the link below to see a couple of pictures are learn more. What is arguably the best use of ivory is to let the elephant keep it for the length of its natural life. Elephants use their tusks in a number of ways that are useful to them in gathering food, defending themselves from enemies and in displays among themselves. That is exactly why the elephant developed its tusks, why it evolved them.

What is inside of the ping pong ball?
Ping pong balls are made of celluloid, a lightweight, flexible plastic. An American inventor, John Wesley Hyatt, discovered this material in the late 1860s after he experimented with a mixture of cellulose nitrate and camphor. Although it is a tough, inexpensive product, celluloid is also extremely flammable because of unstable properties. Originally Hyatt wanted to use celluloid to replace the pricey ivory in billiard balls, but he discovered this fiery danger when billiard balls made with celluloid exploded upon colliding. Celluloid was later used for a variety of products, including combs, collars, photography film, and toys, but it was slowly replaced by newer synthetic polymers. Today, celluloid is mainly used in the manufacture of ping pong balls, and because it is much lighter than other materials and has great tensile strength (causing the surface to remain stiff upon impact), it allows the balls to soar upon impact.
Basic skills in billiards?
Pool is one of the safest sports in the world. According to research conducted a few years back, billiard champions have the highest average age of any sport, 35.6 years. In 1586, the castle of Mary, Queen of Scots, was invaded and captured. The Invaders made a note of forbidding her the use of her billiard table. They then killed her, and used the covering of the table to cover her body. The first coin-operated billiard table was patented in 1903. The cost of a game on the first pay-for-play table: one penny. Before the invention of celluloid and other new-age plastics, billiard balls were made out of ivory. Billiard balls had to be cut from the dead centre of a tusk. The average tusk provided only 3 to 4 balls. Throughout most of the 1800's, the chalk used on the new leather cue tips was carbonate of lime, better known as blackboard chalk. Most chalk used today is comprised of fine abrasives and does not contain a speck of chalk. Billiards was the first sport to have a world championship (1873). No one knows exactly who, when or where the first billiard table was built. The earliest documented record of a billiard table was made in 1470. In an inventory of the possessions of King Louis XI of France, his table was said to have contained the following: a bed of stone, a cloth covering, and a hole in the middle of the playing field, into which balls could be driven. What is billiard cloth made of? Amazingly, the main component of billiard cloth has remained unchanged for over 400 years. Wool was used in the 1500's, and remains the fabric of choice today. It has, of course, undergone some perfecting (and some wool/nylon blends are also produced). Tables originally had flat vertical walls for rails and their only function was to keep the balls from falling off. They resembled riverbanks and even used to be called "banks". Players discovered that balls could bounce off the rails and began deliberately aiming at them. Thus a "bank shot" is one in which a ball is made to rebound from a cushion as part of the shot. The first woman who won in World Billiard Champion was actually a man. The billiard game was outlawed for many years and in different countries: still at the early days of billiard, the game was accused of being immoral. Therefore, this faulty activity and its devoted players were chased by the Church. On the early history of American billiards, when the term "pool room" was still a synonym for horse betting parlour, the game was illegal in many states.
