Thinking of Buying Gold Chains? 3 Quick Steps to Test the Gold Karat.

With gold prices climbing to all time highs , it’s critical to make sure that the jewelry you are considering purchasing is made of real gold. And this task can be even more complicated when inspecting white gold jewelry. Taking your gold jewelry to a reputable jeweler is the most convenient way to ensure your gold is legit. Luckily, there are a few ways of checking yourself that the jewelry is solid gold.

The first way of checking is by using acid. When a jeweler tests gold, they use very specific acids of certain strength, and the stronger the acid is, the better it’s able to dissolve away at the higher karat grades of gold. Since you aren’t able to measure something that precise, you can merely use nitric acid. First make a small scratch on the jewelry with a file in an area won’t be too visible. Then using a dropper , apply a couple drops of nitric acid. If the jewelry is simply plated, the base metal underneath will change color or bubble as it’s dissolved by the acid. If it’s made of gold, there will be no chemical reaction . For gold chains, it’s often easier to test on the clasp at the end of the chain.

The second approach is by visual and weight inspection. Simply hold it in your hand and feel it’s weight. If it feels heavy, there’s a good chance it’s gold. Silver alloys weigh approximately 70% that of gold, so if it’s gold plated silver, it will be a noticeable difference.  14 karat gold and tungsten do have the same density and weight feel, however tungsten is a darker grey metal .

The last method is to check the jewelry to see if it is stamped and hallmarked. Gold Jewelry is required by law to be stamped either in it’s purity form, or it’s karat grade. Common karat grades are 10K, 14K, 18K, etc. Purity is a 3-digit number calculated by the karat divided by 24, since pure gold is 24 karat gold . And then you just multiply by 100. So 14K is 14 divided by 24 times 100, which is 583 (or sometimes written as 585). Likewise , 18 karat gold is 750.

Tips: Be careful when buying from Craigslist . If you decide to buy something from a stranger, ask them to meet you at a jewelry store so the jeweler can inspect the item in question. Also look for a second stamp on the jewelry next to the karat grade. This is from the actual producerof the jewelry, also called a hallmark. Nicer pieces of jewelry tend to have the manufacturers logo which would allow you to trace back the origin of the jewelry. Therefore you can feel more confident you’re purchasing an item that was stamped correctly .

4 Benefits of Cars Running on Water

Arthur Maxwell asked:


Maintaining a car can be expensive. One of the largest expenses motorists have to content with is their gas bills. This expense has grown considerably as the price of oil increases to all-time highs. More car owners are exploring ways to save money on gas. One of the most popular methods of saving gas is by installing a hydrogen generator in your car. This method is so popular, that there are many cars running on water in the US.

Given the pervasive influence of hydrogen generators in the automotive community, let’s examine 4 benefits of installing a hydrogen generator in your vehicle.

Benefit No. 1 Cheap Installation

Hydrogen generators can be affordable, especially if you build one and install it yourself. There are several step-by-step guides available on the internet that will show you how to build and install a hydrogen generator in your vehicle. These guides are cheap, with some of the most expensive guides costing under $100. The raw materials required for the hydrogen generator cost about $150.

Alternatively, you could hire a professional to install the hydrogen generator for you. There are several companies that offer this service, but the cost of professional installation can run into the thousands.

Benefit No. 2 Works on Existing Vehicles

Hydrogen generators can be installed on most vehicles. There’s no need to purchase a new ‘hydrogen generator compatible’ vehicle in order to perform the conversion. Hydrogen generators have a high compatibility rate with most modern, petrol-operated cars.

Installing a hydrogen generator will reduce your dependency on gas without having to buy an entirely new hybrid car.

Benefit No. 3 Increased Mileage

One of the most compelling benefits of a hydrogen generator is its ability to increase your vehicle’s mileage. A hydrogen generator turns water into a gaseous state and pumps it into your engine during petrol combustion. This reduces the amount of petrol used while increasing the mileage your vehicle receives with the petrol used.

There are a large number of factors that come into play when determining the amount of petrol you can save with a hydrogen generator. However, some consumers have claimed that their vehicle mileage has increased by up to 50% after installing a hydrogen generator.

Benefit No. 4 Environmentally Friendly

Hydrogen generators, in their entirety, are eco-friendly. Producing hydrogen generators is a simple affair that requires relatively common materials and resources. This is in stark contrast to hydrogen fuel cells that are used in hydrogen cars. Hydrogen fuel cells currently use rare materials, such as platinum, as a catalyst.

Hydrogen generators also use water to increase the efficiency of petrol combustion. Water ‘burns’ cleanly, and by increasing combustion efficiency, hydrogen generators reduce the amount of petrol used, thus conserving this expensive resource.

In the US, there are many cars running on water. With the price of oil rising to astronomical levels, there has never been a better time to cut down on your gas bills. The next time you decide to purchase a car powered by hydrogen fuel cells or electricity, stop to consider the amazing benefits a hydrogen generator can give you.
