Different metals January 08, 2007 2:38 AM

From about.com
Gold----------Folklore and Facts Gold is believed to have the powers of healing, protection, wisdom, money, and success. When worn, it elevates your personal power. In ancient Mexico, it was linked to the powers of the Sun. In the middle ages, gold tools were used while collecting herbs to make their powers stronger.

Pure gold is too soft to use for most items, especially jewelry which receives a lot of wear and tear. So, it is often combined with other metals, such as copper, to give it added strength. Pure gold is called 24kt, while most gold jewelry is in either 18kt, 14kt, or 10kt gold. If you have a gold chain that is considered 18kt gold, then this means the gold is 18 parts gold and six part of another metal. The melting point of gold ranges from 1380 degrees F to 2732 degrees F.
Jewelers like working with gold because, though it is a heavy metal, it is easy to form.
There also isn’t much to polishing this metal because it does not oxidize. Usually a quick rub with a polishing cloth is all that is necessary.

Often jewelry is also gold-filled or gold-plated. Gold-filled is a gold plating that is either soldered, brazed, or welded onto another metal. To be considered gold-filled, a plating must constitute at least 1/20th of the metal in the article. Gold-plated or overlay, also called vermeil, is most often 10kt or 14kt gold bonded onto either sterling silver or a base metal. This overlay only needs to be about 120 micro inches of gold over the metal.

Silver-------some silver tidbits
Silver was once thought more precious than gold. It is referred to as the metal of the moon and some believe it has power over emotions, the psychic mind, love, and healing.
This is a very soft metal, so it is often mixed with an alloy like copper. Sterling silver originally was created in an area in Germany called Easterling. So that’s where the word sterling came from. To be sterling sliver, the metal is made up of 92.5 percent silver and 7.5 percent copper.
Pure silver, aka Fine Silver (.999), will melt at 1761 degrees F (961 degrees C), while sterling melts at 1434 degrees F (779 degreees C) and the flow point is 1655 degrees F (902 degrees C).
Coin silver melts at a slightly lower temperature than sterling because it has more copper alloy in it; usually any where for 10 to 20 percent of it is an alloy.

Platinum

Symbol: Pt
Melting Point: 1774 degrees C & 3225 degrees F
Specific Gravity: 21.4
Hardness: 4-4.5
Originally, platinum was discovered by the Spanish explorers in Columbia, South America in 1538. They called it platina because it looked similar to silver (called Plata). Believe it or not, at one time, people didn’t know what to do with platinum. They used it for pots and pans. It didn’t become a popular jewelry metal until the early 1900s. Then during World War II, the U.S. government banned the use of platinum in jewelry making, and white gold was used instead. However, it has become popular again for a number of reasons. First, it is a very dense white metal that resists tarnishing. Platinum jewelry has little alloy in it, usually only 10%, so it is considered hypoallergenic.
There are six metals which belong to the platinum family:
platinum
palladium
rhodium
ruthenium
iridium
osmium
All these metals require oxygen to be mixed with the fuel when melting since they have such a high melting point. They resist tarnishing and do not require flux when soldering. Metals in this group can also be cast, but because of their high melting point, a special investment must be used.
Today, most platinum used in jewelry in mined in Russia which controls the amount minded (much like the diamond industry). A large percentage of platinum is used in jewelry making. However, it is also used in other industries such as the medical industry and the automotive industry.

Metal Working Tool August 20, 2007 1:57 AM

From about.com   By Tammy Powley      Two-Hole Metal Punch

How many times have you found yourself in a situation while making jewelry where you need to punch a hole or maybe a few holes in some metal? Even if you don't normally work with metal, this can happen now and then when you are working with pre-fabricated jewelry components.

There are a number of ways to make a hole in apiece of metal. You can use a drill, such as a hand-held drill or drill press. In fact, I'm a big fan of drill presses.

However, sometimes you just need one little hole and it's not that convenient to drag out a lot of equipment, so that's when a little tool like this Two-Hole Metal Punch can really come in handy.

I purchased the tool pictured from jewelry tool suppliers.

According to the information on the Dick Blick web site, this tool can "cut3/32" or 1/16" holes in silver, copper, plastic, or any soft metal up to 14 gauge.

I like these because they are easy to use and small enough to fit inside a tool box. I've seen them range in price from $12 - $20.

Soldering and fusing February 23, 2008 6:08 AM

From about.com
Have you been thinking of picking up the torch and adding soldering to your list of jewelry skills? Here are some resources to help you get started.

Silver Wire Fusing
This is a new book review of a technique that I've heard about before but honestly, until now, have read very little about. I think it has some major potential for metal clay folks as well as wire workers.
Fusing is a technique which involves heating the metal to the point of almost melting, so that the metal sort of melts together. In this article, it talks only about fusing fine silver, but I've used fusing for copper and for sterling silver as well.

Learn to Solder
Follow these step by step procedures to teach yourself how to solder metal jewelry.

What Type of Soldering Torch?
In this article, I discuss the use of the proper type of torch for soldering jewelry, explaining metal temperatures and fuel requirements. I also offer lots of excellent resources to help beginners learn to solder.
The melting temperature of solder is lower than the melting temperature of metal, which this article doesn't really talk about.
It also doesn't talk about all the different fuels available. For example, at my school, we all have a torch at our bench, and it is fueled by natural gas and oxygen (which I prefer).
At school, we also use acetelene, but this should be avoided if possible, as it is a very dirty gas. However, it is good for casting, because it gets alot hotter than our bench torches, so we can melt metal at a much faster rate

Diamonds are usually found in a type of rock called kimberlite. This type of rock is usually found under compounds such as sand, soil or glaciers. Once diamonds are detected, there are different methods used to extract them depending on the environment in which they are found. The majority of diamonds are removed by ope pit mining (excavation to reach diamonds on the surface of the ground)
