Swollen Breasts And Period Cramp At 49




accumulate When samples preserve the issue of safety is of paramount importance if you do not want to end up with a lot of dust rather than a superb rock. Moreover, as the minerals represent something aesthetically beautiful to see it is important for us to show the public how they can be evaluated from different angles, something that in a box for example, is very difficult.


So how do I maintain a collection of minerals
of how to keep safe in addition to displaying the best way possible?

The question in a sense does not require further analysis, because as they say "everyone likes" because there are both forms of storage such as minerals on Earth, but there are some that are much safer than others, all depends on the combination of creativity, security and basic resources. in principle, to save our minerals in a box (cardboard, wood, etc ...) will only achieve that, due to friction that occurs between them, damaged and in some cases to break, either a falling glass or a simple transformation of precious sample into a coarse powder. Despite this, there are ways to ensure the integrity of our signs in the boxes. The first thing is to wrap the pieces with a paper (towel nova) to avoid friction, but if you choose this form must be very cautious because sometimes unwrap and wrap to show whether parts or working with them.

can also take the simple and easy egg cartons to store our samples and offering safety at minimal cost.


Another form of storage of these organizers are plastic. They are sold in most stores dedicated to home and construction area. While not designed for the storage of minerals, are a practical alternative, low-cost . There are various sizes and capacities, on which we should be fine tuned as well could buy about 5 boxes to our collection soon realize that, in our 100 minerals for example, only about 20 fit in it.


Together with the organizers, there are individual cases in this case, are designed for the storage of minerals and that have a protective padding material (cotton or foam) and a space for a label for the basic data of the sample. A disadvantage of such cases is that only allow the storage of minerals small (approx 5x5) so if you have a giant quartz on your shelf, you could hardly keep it in one of these boxes.

The other way is for mineralogists with race. Consists of sample storage in an acrylic base, which also includes basic data recorded mineral, transforming the piece into a sample with elegance and formality. The problem is that the sample to be affixed to the acrylic (with silicone or other adhesives) loses mobility and an important observation angle, depending on the part used as support.


There is an alternative if you want to set the sample by an adhesive. There methacrylate pedestals designed to support the sample (set to measure the mineral) and do not need glue to secure. In Chile, so far, I've only found these bases in "Hobbyteca of Santiago at a price of 10 x $ 10,000

Finally, the best and most complete way to preserve our minerals are being kept in a glass case through which to assess their main characteristics. Also you can add lights to observe them better. If a window is also closed, is guaranteed to be free of dust and aesthetically speaking, I consider it the best way to keep a collection of this kind, though of course, requires a major investment to carry it out.

Some General Considerations:

must be very care when storing minerals of different chemical composition each other because their components can react when in contact with others. Some minerals react strongly to moisture, such as the Halite in wet traps water and then return it causing a puddle of water around it.

There are also radioactive minerals whose conservation requires an appropriate management to prevent contamination. So it is very necessary to know what we want to make up our shelves.

is not advisable to leave the minerals in the open since the elements of climate can cause changes in them (I still remember a chalcopyrite after rain almost becomes a chrysocolla) ____________________________________________________________________

One of the world's largest diamond



start a new section in Mineraland. Giving

news or reviews to draw attention in relation to minerals and rocks, so we continued with encouragement and support to continue the blog.

The

mine workers in Lesotho found one of the world's largest diamonds, a near-perfect white gem close to 500 carats, said Sunday the mining group Gem Diamonds. The diamond was discovered in the Letseng September 8, the company said in a statement, after being analyzed by experts in Antwerp, its value was estimated at 478 carats, with very few inclusions and of outstanding color and clarity.

Letseng is one of the most productive mines in history, where they have found four of the 20 largest diamonds in the world, including the three largest found this century. Before it is cut into gems it is hard to value a diamond, but a spokesman Gem Diamonds said a similar weight stone with lesser-quality color and clarity had recently sold $ 12 million.

"Preliminary examination of this remarkable diamond indicates it will produce a polished stone of the best color and clarity that will break all records, held through a statement Clifford Elphick, CEO of Gem Diamonds. The Minister of Natural Resources of Lesotho, a country located in the mountains in eastern South Africa, praised the productivity of the mine, one of the highest in the world, located over 3,000 meters. Letseng is owned 70 percent by Gem Diamonds and 30 percent the Government of Lesotho.

The world's largest diamond is the Cullinan, discovered in South Africa in 1905. Had a value of more than 3,100 carats before being cut in more than 100 gems, many of which are part of the British crown jewels.

Minerals & Egg Cartons



At the time of collecting minerals and rocks, we need to know that we are dealing with materials that were created over millions of years and by human carelessness of 1 second can damage or tear apart a fall or punch, so that their operation is one of the most important responsibilities of the mineralogist.

addition, in boxes minerals rub together, causing destruction of crystals and for example, your beautiful quartz is transformed into dust after a couple of months so this is not the best way to save, as well as in open a window or on TV since dust can bury forever the spectacular brightness of a pyrite or quartz.

While it is best to expose them in a thin case, there is a simple, free and elegant for the mineralogist newbie, these are: egg cartons. Yes, as it turns out that thanks to its design get a sturdy support for our most precious samples.

Take an egg carton (it costs nothing to ask them on poultry or stores) and put the minerals, pure and simple. Now, to give them more security you can place the egg carton with minerals and put inside another box (shoe for example) making it fit within it, just cut the "egg cup" to serve as a floor for container box .
