Silver products can be cleaned with a pencil eraser. Thus, to test a product whether it is made from pure silver, just use a soft eraser. If the item is made from silver, after using the eraser the item should be fine and no extra steps are necessary to clean it.

How do you find silver?
silver can be tested by putting a small drop of nitric acid on the item.If the spot being tested turns a ugly green color,it is not silver (or at least not sterling). if the test spot turns a creamy color, it is silver. Testing solution (acid) may be obtained from jewelry supply companies. Sterling Silver or Silver Plated: 3 Simple Tests! 1. Silver Markings or "Hallmarks" Surely, the simplest way to determine the grade of your silver is to look for silver markings left by the manufacturer. One of the most common markings is the imprint of the numbers ".925" (900 and 800 are also common). This indicates that your piece is 92.5% pure silver. Silver is often blended with 7.5% copper alloy. This gives the silver more strength than 100% pure, or /fine /silver. 2. The Magnet Test This is another fairly common way to test the purity of your silver -- although I do not recommend using this method alone. Silver is a nonferrous material, meaning that it is not magnetic. For this test, the best tool to use is a rare-earth magnet which is also stronger than most magnets and won't lose strength over time. 3. The Acid Test This is an effective test, however if you are dealing with a piece that you think may be particularly valuable, you may want to try other methods of testing you silver first, as this may damage your silver slightly.

What is better pure platinum or sterling silver?
There's no way i could compare the sterling silver to the test pure platinum. But what i can tell you is that i have tested with test pure platinum and holy smokes! It worked! Now i am set. I could not believe the anxiety i had taking/after the drug screen. I was like "oh man oh man what if". But it worked out for me. Just follow the instructions on the bottle and keep clean a little time prior to taking the test, and it should be smooth sailing. Everyone's different so i wouldn't know the results but i can say that i do believe in test pure platinum!

Multiple choice tests are often considered the least authentic mode of assessment as they generally do not require deep critical thinking or creativity. They tend to focus on rote memorization and do not effectively assess a student's understanding or application of knowledge.
How can you determine that a is not pure silver if you know the mass and volume of the coin?
Divide the mass by the volume to calculate its density. If its density isn't the same as an equal amount of pure silver, the coin has some other metal in it.The density test can be fooled if the coin was adulterated with other metals that average out to the same density as silver, however.
