Pure gold is quite soft and you can leave teeth marks in it if you bite it. This method was often used in the past to test gold coins. Silver is added to gold to make it harder and the more silver which is added then lower the carat that the gold is assigned. In Britain 24 carat gold is pure, 22 carat is very high grade, 18 carat has much more silver and less gold and 9 carat has the least amount of gold.
Bite it. Real gold is heavy but malleable, and when you bite it, it will leave an impression.
To check if it's gold
You mostly see them bite the gold medals because real gold is very soft and malleable. If you bite it, it will leave teeth marks on the medal. It apparently just took with the silver and bronze, too.
To show fhat they are real medala
That is testing the hardness.
why not take the watch to a gold store and have them check it out for you Gold is usually soft so you could use the old bite method to check if its real.
Because gold is soft, your tooth should leave a visible dent.
Type your answer here... TO VARIFY ITS REAL GOLD
Look at the item and see if it is stamped. Check to see if there is discoloration. Bite on the gold. Gold will have an indention. There's a density test and a nitric acid test.
Bite it...well you could find the density of it by this equation density=mass/volume and compare it to the density of gold on the periodic table
