Thursday, November 6th, 2008

When your circumstances require that you suddenly have to take out life insuance you sometimes have to decide quickly.  Deciding over what type of insurance policy is best for your situation, is no laughing matter.  It is something that can have a huge finacial impact on your family and your liquidity in the long run.

Just knowing the basics of life cover is not all that important.  Finding out which life cover option is the best life insurance policy for you to take, given your current situation – that is the question!

If you wanted a quick short term solution that will not sink you financially, you should look at the fact that if you are from Canada you can get Canadian whole life insurance

The risk of the term life insurance policy paying out is small and therefor your premium is small too.  The fact is that once the term has passed your life is no longer covered, must be considered too.

In the long-run it ordinarily is better to have a whole life insurance which is built onto a term that only expires when you die.  That way you do not have to worry about renewing your life insurance policy.  In fact your family can be assured that your life is covered and stay being covered as long as your life insurance premiums are paid up to date.

Something else you you wish to consider is the fact that the whole life insurance policy ordinarily have a built in sum of money that is invested on your behalf by the insurance underwriter. Even with the sometimes slightly higher insurance premium of the whole life insurance policies, it may still be giving the best return for your money.

So if you decided to go for a whole life insurance policy I would suggest looking at an insurance policy with a cash value..

Bronze Casting Information and Bronze Metal History

Thursday, November 6th, 2008

Metal Casting

Metal Casting has been practiced for centuries. Many civilizations have used this alloy for weapons, sculptures, and general pieces of hardware. The popular way to cast bronze is the Lost Wax Casting process which was first used sometime in the 3000 BC near ancient Sumeria. The Lost Wax process is still used to this day and its modern equivalent Investment Casting is very popular with jewelry makers.

Bronze is the preferred alloy for metal working artists as it’s relatively easy to work with and resistant to corrosion. The properties of bronze tend to be stronger than most other alloys, except of course for steel, and lends itself easily to the molding and casting process. Many small foundries like the kind that can be found in a backyard or workshop find that bronze is a great material to work with and with a melting point of 1,700 Fahrenheit or about 925 Celsius many homemade furnaces are able to melt down the bronze quickly and efficiently.

Many modern day artists create their own furnaces with the metal casting in mind. These metal casters employ the Lost Wax Casting method which proves to be the best when dealing with the alloy. The Lost Wax Casting is making an original of the sculpture from wax and then creating a mold using this original. Often times the original is lost during the mold making process so keep that in mind if you want to hang on to the original for whatever reason. Molten wax is poured into the mold which is chased or smoothed of imperfections. During this point, any other pieces are attached and small wax tubes are placed into the piece. These tubes will be how the molten bronze is going to travel into the piece replacing wax with the alloy.  When this is complete the artist will create a ceramic shell around the wax model. What really does the trick on helping to melt the wax is the shell which helps form the molten bronze which in turn melts the wax. When the molten bronze is poured the bronze takes place of the wax. Afterwards, the artist will crack the shell and reveal the bronze piece. If you are looking for a method that transfers every single detail from the wax onto the bronze, this method is going to give you more detail than any other.

Really its up to the artist to add patina or a top coat to the sculpture. The Patina is a chemical that when applied to bronze creates colors and makes the bronze take an aged look. The Patrina compounds used depends on the type of color desired. Ferric Nitrate will make the bronze take on a red or brown color while Sulphurated Potash will make black and Cupric Nitrate will create blue and green. Modern day artists choose to go with a very high polished bronze instead of using these compounds. This step depends solely on the artist’s taste and the look they are going for.

Bronze Casting will remain a popular medium until another alloy is developed that exhibits properties that are easier to manage and are more resistant to corrosion. Casting the alloy is easily done so metal casters that want to experiment are encouraged to do so. Making anything from small figurines, large sculptures, and even cabinet handles can be accomplished with the use of bronze. The only limitations in Metal Casting are with the caster himself.

All About Brass Casting

Thursday, November 6th, 2008

Casting

Brass is a great metal to cast with as it can provide some really great looking results.  Many believe that brass, an alloy of zinc and copper, has been around since our prehistoric ancestors. Today brass is used for a multitude of products from coins to trumpets not to mention a whole bunch of other musical instruments.

The low melting point makes brass a really great material for metal casting since even the smaller home grown furnaces can be used. By adding and subtracting alloys from bronze one can successfully make hard or soft bronzes. Aluminum and tin are sometimes added to bronze to create a layer that is not corrosive and very durable. Whats nice about DIY Brass Home Foundries is that you can use the scrap you have lying around and it will be perfectly acceptable. Locating scrap pieces of brass should be sufficient enough for whatever project you have in mind. Due to brass’ gleam and yellow shine, many artists will use the alloy for sculptures, jewelry, and other decorative items. Other metal casters may choose to use brass for general hardware needs or vintage car restoration, and of course, whatever else they may choose.

Generally there are three casting methods that prove to be suitable for Metal Casting . The nice thing about metal casting is that there are so many methods to experiment with and that casters don’t have to be locked into one method or technique.

Brass Casting casting is usually associated with bronze casting but can also be used for brass and for really any other metal. By using a wax model and covering it with a ceramic shell, artisans are able to inject the molten alloy which replaces the wax. Chipping away the shell will reveal the brass piece. Lost wax casting is used when a high attention to detail is needed. Artists or metal casters looking to create decorative brass pieces or sculptures will find that the lost wax casting technique will meet their needs far better than other techniques and methods.

Die casting is yet another method used for Metal Casting . Die casting is normally used in commercial foundries since the initial start up cost is undesirable for the smaller home foundries. By using a reusable mold created from steel, the caster will be able to create scores of identical products. Die casting with brass should be used if the caster or artists is planning to make multiples of one product and can find a viable market for those pieces.

A very popular method for small foundries today is a type of casting that has been around the longest called Sand Casting. The brass is poured into sand molds and can create a unique look which may be preferred for the artisans. Sand casting tends to be the most economically sensible for small foundries and if the casting does not have to be incredibly attractive then this method is preferable for many.

Whichever casting method is used for casting the brass really depends on the individual. Many find that casting brass to be fun and easy since it does melt rather easily. A large expensive furnace is not a requirement when casting brass so first timers using small home made furnaces will find this alloy attractive. Many have even been able to melt brass in small ceramic pots using charcoal!

Some ideas of what to make with brass include candle holders, plumbing fixtures, and even musical instruments
