Wax dipping is the process of immersing an item in wax. It's often used as another term for bottle sealing. Wax adheres to the item, cools down and creates a coating on the item. In the past this technique was used with spirits and wine bottles to protect the corks, as well as providing tamper proof evidence. Today, bottle caps and corks are more effective and secure than in the past. Bottle sealing wax is mainly used for marketing reasons.
