What is mining?

Two -mass are the growth of buildings in which many offices were located, long before the air conditioning was available, and also long before some of the larger skyscrapers began to have windows that did not open. If you wanted to cool your office down, whether on the ground floor or a few floors up, you opened a window. This could mean that strong designs could blow out papers or at least on the floor. In order to face such designs, in the mid -19th century several companies began to produce mining: severe, often polosphere, glass object that would prevent the papers when exposed to designs. The US and the United Kingdom soon followed to create other companies to make perfect mining. These early representation, especially if they are free of defects, are often highly valuable. Some of the earliest papers can be sold for several hundred thousand US dollars (USD) and there are many collectors of different styles. This is:

• rong> lampwork : papers built around central objects such as flowers, animals or fruit.
• Millifiori : glass technology that produces different glass patterns, often looks like small flowers
• portrait or advertisement : Two -mass is built around someone's picture or around an ad for the company
• Commemorative : Weights are built on a plaque reminiscent of an event or success
• California : Weights can be painted in different colors and colors can be decorated with tools to demonstrate different styles.

Although most of today's heavy weight today is glass, you will find those made of hard materials such as Marble, and there are many made of plastic. They usually have less value if they are not one of the species and are made by craftsmen. In modern times some of these craftsmen increased the podoBU production of mining for fine arts. In particular, it is incredibly realistic that many believed that everything that closed in weights is real. Stankard's weights are part of the collections in many of the most famous museums in the world.

If you are not a collector, and if you have air conditioning, the principle for buying paper today is that it is recalled. There are many to choose, especially from the style of lamp or commemorative style. They are definitely elegant to look, even if their function is now unnecessary. Many believe that the table would not be official without the necessary attractive mining.
