How do you tell the difference between brass and gold?
Brass is an alloy of copper and zinc, giving it a more yellow appearance with slight red tones. Gold, on the other hand, is a precious metal with a distinct bright yellow color and is much softer compared to brass. One way to differentiate them is through a magnet, as brass is not magnetic but gold is not magnetic.
How can you tell the difference between gold and gold plated brass?
1. Gold is denser than brass: weigh the object, and determine its volume (e.g. by measuring the displacement when it is sunk into water in a graduated cylinder). Calculate the density. Gold will come out near 19.4 grams/cubic centimetre; brass near 8.6 g/cm3. 2. Rub against the unglazed ceramic object, real gold leave gold streak brass plated will leave brass streak.
How do tell the difference between brass and nickel?
Brass is a yellow-colored alloy made from copper and zinc, while nickel is a silver-colored metal with a slight blue tint. Brass tends to have a warmer tone and is less shiny than nickel. You can differentiate between the two by comparing their color, shine, and possibly using a magnet (nickel is magnetic, while brass is not).
Can you tell the difference between brass and bronze by sound?
No, you cannot differentiate between brass and bronze solely based on sound. Brass is an alloy of copper and zinc, while bronze is an alloy of copper and tin. The compositions of the two alloys affect their physical properties, such as color and hardness.
How do you tell difference in 9ct or gold plated gold?
One way to tell the difference between 9ct gold and gold-plated jewelry is to look for hallmark stamps on the piece. 9ct gold will have a specific hallmark indicating its purity level, while gold-plated jewelry may not have any such stamp. Additionally, you can also do a simple acid test or consult with a jeweler to determine the material's composition.

How do you tell the difference between brass and copper?
The brass has much lighter color (yellowish to light reddish), then the copper (reddish brown). The brass is copper mixed with zinc. The more copper in the mix, the darker the color.
How did a miner tell the difference between real gold and fools gold in the great horn spoon?
They would smash it with a rock.
How do they make 28k gold jewelry?
Well, first they take brass, then they stamp "28k gold" on it, knowing that anyone who thinks you can go higher than 24k (pure gold) is probably unfamiliar enough with gold to be able to tell the difference between brass and gold.You don't see even 24k gold jewelry often; it's too soft and doesn't wear well. Jewelry is usually made of a lower gold content alloy (with, usually, copper, silver, and/or nickel) that's substantially more durable than pure gold is.
What mineral is sometimes confused with gold?
Iron Oxide. Pyrite is known also as "Fool's Gold"

What metals are used for a ship's porthole and how do you tell what metal it is?
Special types of brass and are used. Brass looks like gold but is slightly duller, steel is a darker iron grey.
What happens when you combine brass with ethanol?
Hard to tell- regular ethanol is about 10% and E85 is about 15% so maybe 5% difference between the two in or normal fuel supply as of 2014. Brass and E85 ethanol are very reactive with each other
