Tungsten carbide provides a durable, lasting option for your jewelry purchase. Because of its ability to sustain wear and tear, tungsten carbide has become a popular metal for wedding rings.

What is Tungsten Carbide?
Tungsten carbide is a durable metal that can be permanently polished to maintain a new appearance for years to come.

Cost
Tungsten carbide is typically a much less expensive alternative than other metals such as platinum and gold.

Shaping
Because the hardness of tungsten carbide, jewelry made from this metal will not bend or lose its shape.

Shine and Luster
Tungsten carbide jewelry has, and maintains, as much shine and luster as other popular jewelry metals.

Care
Water and a mild soap can be used to clean your tungsten carbide jewelry. Do not use chemicals or a jewelry-cleaning machine, as this may cause damage or discoloration.

For many years, sport anglers relied on lead weights to carry their lures to the bottom of a lake or river. However, biologists discovered that the toxic nature of lead posed a threat to aquatic life. Lost lead weights had begun to pollute the lakes and rivers. Fortunately, a safer alternative was found and, today, lead weights have been largely replaced by tungsten. If you are using a tungsten weight, you should paint it to camouflage the shiny surface before casting your line in the water.

Instructions

1
Clean the tungsten weight with a cloth and some rubbing alcohol. Allow it to dry.

2
Paint the weight in the color you've selected. Use enamel metal paint and a small paintbrush or strong nail polish and a nail polish brush. Let dry thoroughly. Apply a second coat.

3
Inspect your collection of tungsten weights before each fishing trip. Over time, the paint will begin to flake with repeated use. When this happens, sand off the flaking paint and reapply a new coat of paint, following the steps described above.

Tips & Warnings
Tungsten is a very dense and strong metal. Because the surface of a tungsten weight is so strong and smooth, the surface cannot be roughed up using normal tools and the paint will not adhere to the surface as well as it would to other metals.

A tungsten light bulb refers generally to incandescent light bulbs, which are lights that generate light by heating a metal wire or filament with electricity until it becomes white hot and glows.

Definition
Tungsten light bulbs are named for the metal tungsten, a gray material that has an extremely high melting point. Because of its high melting point and its strength, it makes for a good filament in light bulbs. A filament is a metal wire that glows when electricity is channeled into it. Light bulbs that use this method to generate light with heat are called incandescent lights.

Popular in Photography
Tungsten light bulbs and other incandescent bulbs are often used in photography as an alternative to flash lights because the continuous light they provide allows photographers to see shadows. They pose some challenges, however. When used in a studio, the bulbs can make the room extremely warm. Since the light given off by tungsten bulbs is of a lower temperature than the sun, outdoor film is unsuitable for use with the lighting. Instead, photographers use special tungsten film or use a tungsten filter on the light or camera lens to make the colors in photographs appear more natural.

History
The history of tungsten light bulbs dates back more than 100 years. Modern tungsten light bulbs were developed by General Electric around 1906. Before that, inventors experimented with many other kinds of light bulbs with alternative filaments. However, other materials had lower melting points and did not last as long as tungsten bulbs.

Burning Out
Over time, tungsten filaments can wear out. The repeated heating of the metal causes it to slowly evaporate. The wire slowly gets thinner and more fragile until it breaks, either spontaneously or by jostling. If you drop a bulb and the glass doesn't break, shake it. If you hear a rattling sound, that means the tungsten filament wire has snapped and the two ends are slapping against each other.

Tungsten film is used for studio photography. The color temperature of average daylight is 5,000 degrees Kelvin. The term "tungsten" refers to a color temperature of 3,200 degrees Kelvin. Therefore, tungsten film is designed to be used under studio lights of the same color temperature, called tungsten lights. If you use tungsten film outdoors instead of under tungsten lights, your photos will have a blue cast. Similarly, if you use a different type of film under tungsten lights, your photos will have a gold cast.

Instructions

1
Store your tungsten film in a dark location so it is not damaged by light.

2
Open the back of your camera and, while still in a dark location, place the tungsten film into the cylinder hub so it clicks in place and pull the leader of the film until it wraps slightly around the hub on the other end of the camera.

3
Close the back of the camera, turn the camera on and listen to the film load. If you do not hear a loading noise, you may have to open the camera and pull the leader a bit farther. Once the film is loaded, turn your camera off until you are ready to use it.

4
Situate your subject or props in the area where you plan to take photographs in your studio.

5
Set up your three tungsten lights on stands so your subject or props are evenly lit. You may have to move around the lights and raise and lower the stands until you reach the perfect lighting. Use light umbrellas if the lights are too bright for your space.

6
Turn on your camera and take photos as you normally would. When your film roll is complete, store it in a dark location and follow Steps 2-3 to reload your camera with another roll.

Tips & Warnings
Tungsten film can be purchased in most photography supply stores and is developed in the same way as any other type of film.
