Identify The Real Gold Jewelry at your Door Step

By performing some simple experiments at home one can easily identify the fake and real gold jewelry like checking for stamp markings, attraction towards the magnet, density test, nitric acid test. Further, scratching of gold jewelry against the ceramic surface is another method for testing real jewelry.

Marking Test Most of the gold jewelers mark their stamps (by denoting the karatage of gold) on the gold jewelry designed by them.

Magnetic Test It is another method for identification of gold purity. If the jewelry sticks to the magnet, then the jewelry is not real because real gold has no magnetic attraction and does not stick to the magnet.

Density Test This test can be performed by placing the jewelry in a beaker of water, if it sinks, then, the jewelry is of real gold because gold has greater density than any other metal.

Acid Test For, performing this test, nitric acid is used. By putting some drops of nitric acid on the gold jewelry shows no reaction as, gold is a non reactive metal whereas, fake jewelry changes its colour.

Scratch Test On scratching the real gold jewelry against a ceramic plate or tiles leaves a golden streak, however, dark or black coloured streak observed in case of fake jewelry. Discoloration occurs in the false jewelry on wearing this.

The most accurate tests for testing the purity of gold are performed by using fluorescence spectrometers (XRF). Such type of instruments sends X-rays through the tested sample. The atoms of the tested material become excited and move into a higher energy state and release energy in the form of radiation while returning into their ground state. XRF detects as well as read the radiation. By observing the radiation, we can easily find out the material by which the jewelry is made of.

We can also clean the gold jewelry at home by adopting simple and small process of cleaning with the household articles like dish detergent, water and tooth brush. Take small amount of dishwashing detergent or soap into a bowl containing water; soak the gold jewelry into the solution for at least 15 minutes. Now, take out the jewelry from the soap solution and gently clean the surface of jewelry with the help of a soft bristled tooth brush. Finally, rinsing is done with warm water and then, dries it with a muslin cloth. The gold jewelry leads to shinier as well as brighter.

Are you Experiencing Cactus Like Feeling with Woollens?

Wool is derived from sheep and contains lanolin, a kind of natural oil, which is responsible for causing allergies to several people.  The most common wool allergy symptoms in the people include irritation, itching, rashes, and hives on the skin. It affects the eyes and leads to puffiness, itching as well as redness. It also causes nasal problems like running nose, sneezing, nausea, congestion and other problems related to respiratory tract. However, the people who are allergic to lanolin of wool also show the similar allergic reactions when exposed to the other products which contain lanolin such as wool wax, cosmetics and other personal products. However, only wool alone cannot be the actual cause of allergic reactions such as lumps and red bumps all over the skin, but due to the direct contact of wool with the skin generally causes itching and irritation because of the nature of the woollen garments.

In the process of manufacturing of woollen garments like sweaters, scarves, socks, jackets and gloves synthetic chemicals and colours are required. Both the chemicals and colours can be the reason for different allergic reactions to the people who are not familiar about the allergic reactions caused by synthetic chemicals and dyes used in the making process of woollens but do complain about wool allergies. These only trigger or accelerate the allergic reactions.

A person who is allergic to wool has the same kind of allergic response just like in the persons having an allergy due to pollens, dust and pets such as rashes on the body including face, arms, hands, feet, etc. This may appear immediately or may occur in a couple of days just after coming in the direct contact of wool.

Till date, there is no particular treatment for the allergic reactions of wool; however, some antihistamines and allergy shots can also be given to the patients at the onset of allergic symptoms. Further, persons should stop using those products which consist of wool if possible.  So, to avoid such kind of allergy one should put cotton clothing in between the skin and the woollen garments and really it is enough to solve the itching problem.
