    do an acid test, not sure which acid you’ll need to look it up on the net to see what they use and then go and buy a small bottle as you only need a few drops.

    aside from the 9.999, which would be it’s purity, al gold bars are stamped with other markings, to identify the year and the person resonsible for turning it into the bar. If it only has 9.999 it could be another metal which is almost pure.
    an easy way would be to weigh the thing, then calculate it’s volume (length x width x height ) and look up gold’s density.
    density is mass x volume, and so you would be able to see if it is close to the expected weight, given it’s size.

    ok this what you do and still afford to keep whatever it is you have
    Density of an object is specific for each type of thing
    Density is found like so
    Density= MASS/VOLUME
    take the bar and find its weight in grams ok
    then get a beaker or something that you can measure mL in and find the volume of the object
    Once you’ve done this plug the two numbers into the formula
    the answer you get should be close to 19.30 which is the density of gold.
    hope that helps

    I would dip it in a vessel containing water up to the rim and collect all the water that overflows. Measure the cubic capacity of this water and it should also be the weight of water. You can then use Archimedes principle to find ou if you really have a bar of gold.
    Eureka!!!!

    Where do you live in Brigadoon my wee pal? .

    I’m not sure why you wouldn’t want to take it to a ‘shop’ but that is probably the best thing you can do. An expert jeweler can tell you if it is real.

    I concur that the easiest way is to measure the density as accurately as you can.
    I haven’t the slightest idea how big a gold bar you are talking about – it could be anywhere from 1 oz to 100 lbs. You’ll need to find a scale that is appropriate for the weight you have.
    As for the volume, a straight-up displacement is probably best. Add the bar to a container of water with a clearly marked water level. Then after the bar is added either take note of the new level and find out the difference in volume, or pour out water (keeping it) to return to the old level, and measure the quantity of water you poured out.
    If the density works out to close to 19.3 g/cc, you are in luck, it sounds like.

    Bite it. If chocolat comes out then its not gold. Other than that you may be rich. Got any more?

    Give it to me. I’ll find out for you.

  10. Away With The Fairies says:

    Gold is made into a large number of different bars of different weights. The most well known are the large ‘London Good Delivery Bars’ which are traded internationally. These weigh about 400 Troy Ounces, i.e. 12.5 kg/ 27 lbs. Each. Others are denominated in kilogrammes, grammes, troy ounces, etc. In grammes, bars range from 1 g up to 10 kg. In troy oz, from 1/10 tr.oz. up to 400 tr.oz.. Other bars include tola bars and Tael bars.
    Hope that helps.

    Check the volume in cm3, and weigh it accurately. Gold weighs 19.3 gm per cu cm.

    It is so heavy, that just holding it in your hand, you can tell it is different (weighs 2 1/2 times as much as iron or steel).
    Also, a jeweler can probably tell you easily.
    Also, American gold bars are usually cast in troy ounce sizes. A troy ounce is about 31.103 gm. Look for multiples of that

    You will probably find it is worthless base metal.

    Hello,
    (ANS) The only way you will know for certain if the bar you have IS definately gold is to take it too a jewellers or jewellery shop. I wouldnt be at all worried or embrarrased in doing this, a good competant jewellery wont blink an eye at this even if its 100% real gold and worth thousands of pounds in value. Just remember a good jewellery will have seen & handled many such gold bars in their time.
    **People only tend to buy Gold Bars for investment purposes anyway. ie. Gold soveriegns, 1/4 oz bars, 1/2oz bars, 1oz bars.
    **Dont forget that gold is classified in terms of how many carrots the gold item contains. 9 carrot, 24 carrot,etc. This gives you an idea of the bars purity of gold content. The gold bricks/bars held by the bank of England are 100% pure gold as far as I recall.
    **The UK Governement & the Bank of England have many many millions of £ all in the form of gold bars. But in that case its a massive room from floor to ceiling with the stuff. Its called the gold reserve!!.
    **Otherwise I cannot see how you can prove the vaildity of the bar as gold without an expert seing it.

    I would first check the density of the bar. It should exactly match that of gold. weigh the bar on a very accurate scale.
    Dip the bar in a bowl that is completely full of water.
    Capture the water that flows over the edge of the bowl. measure how much water is displaced by the bar.
    The density of water is exactly 1.
    If you measure the weight in grams and the water in milliliters
    the arithmetic should be easier.

    if it turned green, its copper. the statue of liberty is copper and it turned green, plus its a reaction to the oxygen in the air. it is not likely to be gold, it could be fools gold or brass. brass dosent turn color. or it could be painted iron.
