Zinc nitrate appears as colorless lumps or crystals with a slight nitric acid odor. It is soluble in water and alcohol and loses water of crystallization between 105 and 131°C. It is highly deliquescent, i.e., it tends to absorb water from the air and dissolve in it.
Zinc nitrate is typically used to create white to cream colored patinas on brass and bronze. It is also added to cupric nitrate patina formulas to aid in prevention of unwanted copper oxides, which appear as reddish patches in an otherwise blue or green patina.
Zinc nitrate is a strong oxidizing agent and corrosive. Avoid contact with skin and eyes. Wear proper protection such as a respirator to avoid breathing zinc fumes.
