Sealing wax is a type of wax used to create a seal on letters, documents, or packages. Traditionally, it is melted and then stamped with a seal, often made of metal, to leave an impression. This practice dates back to ancient times and was commonly used to ensure the authenticity and confidentiality of correspondence. The wax is typically made from a blend of natural and synthetic materials, including resins and dyes, which give it color and durability. Sealing wax can come in various forms, such as sticks or beads, and is often used in crafts, invitations, and formal correspondence to add a decorative touch.
