How to Test Silver with Nitric Acid

Do you have a piece of old vintage jewelry? Check to see if it real silver using the Nitric Acid Test. Simply use a drop the acid, and if your piece of silver turns green than unfortunately it’s impure and mixed with either nickel or copper. If it turns white then your piece of jewelry is sterling!

Caution: Nitric Acid is an acid, and will harm skin if contacted or lungs if inhaled. Please use all precautions necessary, using gloves, safety goggles, and an well ventilated area to be safe.
