Marble how is it made




















That being said, it still takes quite a lot of work to quarry. Marble deposits can often be enormous, and explosives are needed in order to begin breaking up the rock. Machines then help create grooves in the stone, which are leveraged to split it from the rock face. Marble is still used extensively in building today and can be seen in churches, city halls, and historic buildings alike.

However, it can also be found in the humble home. Marble countertops are beloved by homeowners for their beauty, and especially by those who love to bake. Because the surface always stays cool, it prevents buttery doughs from getting too soft and helps temper chocolate to the perfect consistency to make truffles, bonbons, and other treats. Although marble countertops need frequent sealing and care must be taken to prevent staining and acid erosion, the effort is worth it for the suite elegance the stone will give your kitchen.

Of course, you can use marble elsewhere in your home. Marble floor tiles can look stunning in an entryway, and can also be used to create decorative backsplashes in the kitchen or in the bathroom.

Most marble is white, consisting of pure calcite, but the presence of other minerals can cause it to change color. For example, the influence of iron will turn marble into a salmon pink, a deep red or green is the cause of serpentine, and limestone that was loaded with graphite-rich fossils will become a marble that is dark and gleaming like gunmetal.

Once the marble is extracted from the earth, it can either be crushed into stone or maintained in large slabs that display the time and hard work involved in its creation. Each stone is individual and tells its own story of how it came to be. It can then be highly polished to reveal the depth of its colors and patterns.

When a slab of marble is selected for use, as a countertop for example, a template is laid against it to select the area that best showcases the personality of the natural stone. The stone is then cut and shaped before being installed as a beautiful new centerpiece to be admired and enjoyed.

Marble is a stunning and strong material , but it requires a little loving attention to maintain. On the Mohs scale, marble is rated a three, so it is relatively easy to scratch with another hard, sharp surface like a knife or a pan. Marbles and marble games for children continued to be a popular form of entertainment well through the Middle Ages. Unfortunately, youngsters playing marble games came to be seen as delinquents, and efforts were made to restrict their marble-playing activities.

Most of the marbles used in medieval and Elizabethan times were made from clay. Around , water-powered stone mills in Germany began producing more polished versions from the marble and alabaster quarries nearby, especially in the regions near Coburg and Oberstein. The word marble is derived from the German term "for the rock," and has come to mean any small, round sphere used as such. Soon the mills began grinding out versions from agate, limestone, brass, and gemstone, and these large operations could grind a marble into shape at the rate of about an hour.

This made Germany the center of marble manufacturing for several centuries. Glass marbles, the most common version of the object today, only came into existence relatively recently in the history of the object. It is debated whether they originated in Venice, where glassblowing had become a well-developed industry since the ninth century, or back in Germany.

Historians point to as the invention of marbelschere marble scissors by a glass factory employee in Germany. This tool resembled a pair of tongs with a small cup on one end and a slicing device on the other. A molten glass rod would be forcefully inserted into the cup, and the worker would then twist the cup, which would help form the sphere of the marble.

Squeezing the tongs shut sliced off the rest of the glass. Such marbles can be identified by their pontil marks, the two tiny tags at each end of the sphere where the cooling glass was severed from the rest of the rod. The objects were further cooled inside a wooden barrel and then taken up with an iron spoon and inserted into an annealing oven, a process which yielded a tougher piece of process which yielded a tougher piece of glass not likely to break or become brittle.

Marble manufacturing migrated to American shores in the later decades of the 19th century.
