Pack of 6 Silver Testing Acids

Testing acids come in sturdy plastic bottles with an internal baffle to prevent leaks and maximize safety. Plus, it allows the user to precisely drop the amount needed. Only a small drop is needed, so you will get hundreds of tests out of each bottle! Each bottle contains 12 grams of solution (include six bottles). Avoid ingestion, and contact with skin and eyes.

While testing items that are said to be silver:

• Scratch or rub the metal you are testing onto the stone; hard enough to make a visible streak or mark onto the stone. The silver will change colors based on purity!

• 90%-100% = Dark Red

• 80%-90% = Light Red or Brown

• 65%-75% = Light Green

• Creamy white results will indicate that the item is sterling silver. Green results indicate that the item is silver-plated.
