Marble HISTORY! Marbles are small, hard balls made from clay, stone, wood, glass, steel or any other suitable material. They have been made for thousands of years and games with marbles are popular in countries around the world.

DEVELOPMENT AND HISTORY The earliest marbles were made of flint and stone and baked clay. Examples have been found in archaeological sites around the world and some of these, from Rome and ancient Egypt, can be found at the British Museum.

There are frequent references to marbles in Roman literature and it is probably fair to assume that the Romans took this popular form of entertainment with them to all parts of their empire.

For centuries thereafter the marbles were made of common stone or in some cases, real marble. China and crockery marbles were introduced around the year 1800 and before that glass marbles had been made in Venice. However, it was only when a German glassblower invented a tool called the marble scissors in 1846 that production became quick enough to make the sale of glass marbles to the public an economic proposition. These marbles became increasingly popular throughout Europe and America. An enormous variety of colors were used and intricate patterns were created within the glass.

Clay marbles began to be produced in bulk from about 1870 onwards on both sides of the Atlantic. In the 1890's the first machines for the manufacture of glass marbles were, introduced. However, machine production remained low until the 1914-18 war in Europe cut off supplies of marbles to North America. This stimulated the machine production of glass marbles in the U.S.A. This production technique and the machines themselves are now found in many countries, east and west.

At the time of writing, there are only thought to be three people in the world making glass marbles by hand. One of these modern, handmade ranges is available through the House of Marbles and one can still sometimes find early examples in antique shops. However they are much sought after as collectors' items and are becoming increasingly scarce. A marble made of pure, ground marble, or other suitable stone, is highly prized and regarded as being the most accurate for shooting. They are expensive and therefore they are rare. Conversely, clay marbles are very inexpensive, but they tend to be inaccurate in dimensions and dull in appearance and, although they were once the most common of marbles, lack of demand has made them hard to find. These days, marbles are made from all sorts of materials, but glass remains by far the most popular. Glass lends itself to machine production and provides an article which is appealing to the eye and the touch.

MACHINE MANUFACTURE The actual manufacturing process seems easy, although technically it is quite difficult. The glass is melted in a furnace and poured out. Different colored glasses are injected into the flowing glass if inserts are required in the marble. As the glass descends from the furnace, shears cut it into small cylinders of a regular size. These drop into moving, mechanical rollers which round them off and leave them to cool

you do no longer say no count if it used to have a shine to it or no longer. If no longer, the only way you are able to appropriate get it polished is thru somebody with a sprucing wheel and the nicely suited supplies - expert in the sphere. If it has in basic terms gotten somewhat boring, then attempt a thick cotton cloth (like a bathtub flannel), somewhat dampened and dipped into talcum powder oftentimes(even flour from the kitchen) and using a great variety of elbow grease, firmly rub in around motions, doing a small section at a time. Will take extremely a whilst although - reckoning on the marble as stated. you additionally can use toothpaste - this is a comfortable abrasive - and could start to polish it. in case you will hit upon some funds, get some moist and dry sandpaper - around 1800 to 2000 or larger grit. despite if this is going to take an quite long term. Failing each and all the stressful artwork for effects which won't be as much as scratch, why no longer purely the two gently spray the object with some sparkling laquer. or maybe purely some cooking oil, then buff it. this is all I used on exceedingly rocks and shells that my babies accrued whilst youthful to deliver out the colour and supply them an incredible sheen. could ought to do it each and each couple of weeks or so, yet they oftentimes outgrew them in the previous it grew to alter right into a chore. My youngest kd (in basic terms approximately 23) those days moved out lower back. whilst cleansing up his room, i got here across a colourful rock he has had with the aid of fact he exchange into approximately 6 or 7. It exchange into one I had gently sprayed with a much less high priced can of laquer - It nevertheless seems great - i exchange into going to toss it, yet then desperate to maintain it afterall!

They were originally (hence the name). Nowadays they are usually made from glass or agate. I'm sure you can find ones made of marble too.

Marbels have been made out of glass since the 20's. The Great Depression years.

Marble is made of polished stone, I presume.
