Wax seal stamp

Wax seals are marks of authenticity and identity used for millennia on documents and correspondence.

About this subject

Wax seals originated in antiquity as a way to ensure the integrity of confidential documents. Civilizations such as the Egyptians, Greeks, and Romans used clay or wax seals to close important messages, often with engraved rings or signets. In medieval Europe, the practice became entrenched: nobles, clergy, and merchants stamped letters with coats of arms or initials in molten wax, making the seal a symbol of authority and authentication. The practice peaked between the 12th and 19th centuries, especially in official documents, wills, and personal correspondence.

Making a wax seal involves heating wax (traditionally beeswax mixed with resins and pigments) and applying it to paper, followed by pressing a metal stamp. Each seal is unique and difficult to forge, as it carries individual marks, coats of arms, monograms, or designs. The color of the wax also held meaning: red was used by royalty and ecclesiastical institutions, black for mourning, green for commercial documents, and gold for special occasions.

With the advent of adhesive postage stamps and envelopes in the 19th century, the use of wax seals declined but never disappeared. Today, it is valued in ceremonies, weddings, formal invitations, and handcrafted stationery. Collectors seek antique and modern signets, and the technique is preserved by enthusiasts of lettering and fine paper. In Brazil, the use of wax seals dates back to the colonial period, when official documents were sealed with the Portuguese coat of arms.

Interestingly, the word 'signet' (from Latin signetum) refers to the instrument that stamps the seal, while 'lacquer' or 'sealing wax' refers to the wax itself. The act of breaking a seal to read a letter still evokes a sense of mystery and privacy, keeping the tradition alive in a digital world.
