Question: Question: how were letters sealed in the 1800s I found the following answer on Google: If the impression is made purely as a relief resulting from the greater pressure on the paper where the high parts of the matrix touch, the seal is known as a dry seal; in all other cases a liquid or liquified medium (such as ink or wax) is used, usually in another color than the paper. Is that a correct answer? Yes or no.
Answer:
No
