Underseals

Underseals are a type of seal used in maritime and naval contexts, primarily for securing documents and ensuring their authenticity. They are typically made of metal, such as brass or bronze, and are designed to be impressed onto paper or other materials. The process of applying an underseal involves pressing the seal onto the document with a specific amount of force, creating an impression that can be verified by experts.

Underseals are commonly used in naval and maritime environments due to their durability and resistance to wear and tear. They are often used to authenticate official documents, such as orders, reports, and correspondence, ensuring that the documents have not been tampered with. Underseals are also used to authenticate personal documents, such as letters and certificates, in maritime and naval contexts.

The use of underseals in maritime and naval environments has a long history, dating back to the 17th century. They were originally used by naval officers to authenticate their orders and reports, ensuring that they were legitimate and had not been altered. Over time, the use of underseals has become more widespread, and they are now used in a variety of maritime and naval contexts.

Underseals are typically made by skilled artisans, who create the seal using a mold and a casting process. The mold is designed to create a specific impression, which is then cast into the metal. The resulting seal is then polished and finished to create a smooth, durable surface.

In recent years, the use of underseals has declined in favor of digital signatures and other electronic authentication methods. However, they remain an important tool in maritime and naval contexts, and are still used in a variety of applications.
