So This Is Christmas

Merry Christmas is such an infectious feeling I like to feel that way all year around.

So if you are visiting just before Christmas, just after Christmas or even here on Christmas day I am sure you will find something of interest for you and in the spirit of Christmas.

It may be said that Christmas is no longer a celebration but this must be spoken by people that have never had trouble closing their eyes on Christmas Eve in an expectation of what maybe left for them on the carpet under the tree.

I continue to look forward to the surprise on my Grandchild's faces to this day at Christmas events.

Merry Christmas - Merry Christmas - Merry Christmas

The Amazing Selection of Tungsten

By Glenda Michael


Some tungsten rings may have different types of edges such as round edges or ridges for a cool look. You can even choose a tungsten ring in different levels of color ranging from dark gray to light gray. Tungsten carbide rings and jewelry will not show flaws and will resist wear better than other types of metals.

To care for tungsten in the proper way, you can clean it with a mild cleaner and wipe to dry with a smooth, soft rag. You should not store your ring next to diamonds, as diamonds are the only thing that can scratch or do any kind of serious damage to this type of ring. (It is actually a good rule of thumb to store diamond jewelry separate from all other pieces, even other diamonds.)

If a piece of jewelry, such as a ring, is sold strictly as tungsten only, then it is basically just a steel ring. Tungsten without carbon added to create tungsten carbide can actually be scratched quite easily. Rings and other jewelry made with the right formula should not scratch because the element of carbon is present. If you purchase what you believe to be a tungsten carbide ring but the ring has been carved then it isn't a true tungsten carbide ring. (Do not confuse this with designs that look carved but were actually molded when the ring was made, or laser engraving-- both of these processes work exceptionally well with tungsten carbide.)

Tungsten was discovered in the late 1700's and was known back then as wolfram. After a bit of work and some very tedious experiments for several years scientists concluded that this new substance could be used to make a new metal. In 1783 two brothers, Jose and Fausto Elhuyar found an acid in wolframite that was similar to the one found in tungstic acid and were thus able to isolate the tungsten by reducing the acid in it with charcoal. The brothers are recognized as the ones who discovered the element of tungsten.

During the Second World War, tungsten was very important. Portugal had a lot of wolframite ores that were used to make tungsten. Due to these ores Portugal had pressure put on it from both sides of fighting. These ores were beneficial in making tungsten for materials used for weapons.
