In one sentence, describe what the following article is about: Get a dropper and fill it up with white vinegar. Hold your metal object firmly in your hand or set it on a table. Place a few drops of vinegar onto the object. If the drops change the color of the metal, then it is not pure gold. If the color stays the same, then it is pure gold. Position a black jeweler's stone on a table. Hold your gold piece firmly in your hand. Wipe it across the stone firmly enough to leave a mark. If the mark that you've left on the stone is solid and gold in color, then the piece is pure. If there is no line or only a faint one, then the piece is likely plated or not gold at all. Be careful with this method as you run the risk of damaging your jewelry. You also have to use the right type of stone or the marks will be meaningless. You can get a jeweler's stone through a jewelry supply store online or by talking with your local jeweler. Set an unglazed ceramic plate firmly on a countertop or table. Hold your gold item in your hand. Scrape the item against the plate. Watch to see if a streak or line of any type appears. A black line indicates that the item is not gold or is plated. Coat the top of your hand with a thin layer of liquid foundation. Wait until the foundation is dry. Press your metal item against the foundation and rub. Authentic pure gold will leave a line in the makeup. If you do not see a line, then the object is plated or another metal. This is a small hand-held device with a probe at the end that you can buy online or through a jewelry supply store. To analyze a metal, you rub a conductive "tester" gel on to the metal item. This gel is usually available for purchase from the same places that sell testing devices. After you've applied the gel, rub the probe against the item. How the metal responds to the electricity will indicate whether or not it is pure metal. Use the instructions that come with your tester to determine the exact results. Gold is a conductive metal, so a pure gold piece will have higher readings than a plated one. This is a machine that many jewelers use to instantly determine the quality of a metal sample. Because of its cost this method may not be suitable for home use, unless you plan on using it regularly. To use an XRF scanner, place the piece of metal inside, activate the machine, and wait for the read out. If you keep getting mixed results or if you'd like to verify your finding, talk to your jeweler about getting another professional opinion. An assayer will perform a deep analysis of the content of the metal. This can be a costly option, so only use it if you believe your item may be worthwhile.
Summary: Apply some vinegar to the surface and look for a color change. Rub your gold against a jeweler's stone. Rub your gold across a ceramic plate. Test your gold against liquid foundation makeup. Use an electronic gold tester. Insert your gold into an XRF machine. Take your gold to an assayer.

Problem: Article: The root of your anger may be internal or external. Internal sources of anger include perceived failures, injustices, and frustrations. External sources of anger could be losses, teasing, or humiliation. It can be very easy to become mad at someone needlessly if you have a tendency to displace your anger or your bad mood. Taking your displaced anger out on other people is not a healthy way to manage your emotions or your relationships. To avoid displaced anger, try the following: Ask yourself, "what is really bothering me?" Then ask yourself, "what is the worst thing about that?" This will help you pinpoint exactly why you feel bothered. Think about why you feel like you need to redirect your anger (for example, if you feel powerless to address a difficult work situation, you may take your anger out on someone at home). Write down the different things that are causing you to feel negatively or stressed. Try to deal with each stressor or annoyance separately, rather than rolling them together all into one big stressor. Apologize to someone if you have been short with or rude to her through no fault of her own. You might say something like, "I'm really sorry that I snapped at you about dinner. I am a bit overwhelmed at work and I'm having trouble dealing with the stress, but that's not your fault. How can I make it up to you?" Holding onto resentments for things that happened in the past is a common reason for feeling mad at someone. Resentment is not healthy, and letting go of those feelings is the best way to move on. To move on from resentment, try the following: Acknowledge that your feelings of resentment don't serve a productive purpose. Realize that feeling resentment cannot actually change the past. Accept that you cannot control the actions or feelings of other people. Forgive if you can forgive or try to forget if you feel that you cannot forgive. You might feel mad at another person for doing or not doing something that you expect them to do. However, she may have no idea that you expect her to do that thing! If you feel like someone is not meeting your expectations, try voicing those expectations and having a conversation about whether they are reasonable. For example, you may feel mad at a coworker who never contributes to the daily coffee fund but drinks coffee every day. She may not realize that she is expected to pay into the fund or you might find out that she has a sick child and many medical bills. Having a conversation about your expectations instead of letting yourself feel mad can help strengthen your relationship with her. One of the best ways to avoid getting mad at someone is to truly understand where she is coming from through understanding. Getting to know someone better and digging deeper into why she may act a certain way can help you feel empathetic towards her. Compassion will usually override feelings of anger or annoyance. Particularly if the person you're trying not to be mad at is a loved one, try to picture your life without that person in it. Think about all of the things that she contributes to your life and allow yourself to feel grateful for all that she does. Keeping a gratitude journal is a great way to make a habit of practicing gratitude. The acronym HALT stands for "Hungry, Angry, Lonely, Tired." It is a common recommendation in 12-step programs to tell yourself to halt (stop) and evaluate whether you feel any of those things before you lash out at another person. For example, if your husband gets home late and you feel mad at him, before you express that anger, think about yourself first. Realize if you feel hungry, angry, lonely, or tired and think about whether those factors are influencing your feelings towards your husband. Eat something, relax on the couch for a few minutes, then ask him about why he is late.
Summary:
Be mindful of the real source of your annoyance. Let go of resentments. Consider whether you have unexpressed expectations. Develop empathy. Practice gratitude. Remember to HALT before you speak.
