Impression seal

Imagine you have a stamp that you can use to make a picture on paper. You press the stamp onto an ink pad to get some ink on it, and then you press the stamp firmly onto the paper to make the picture.

Now, imagine a special kind of stamp called an impression seal. Instead of making a picture, the impression seal makes a special mark or design on something called a seal surface. The seal surface is usually made of materials like clay or wax.

To use an impression seal, you first have to prepare the seal surface. This means you may need to heat up the wax or soften the clay so that it is easy to make a mark on it. Once the seal surface is ready, you take the impression seal and press it firmly onto the surface. Just like with a regular stamp, the seal leaves a mark, but this mark is unique to the impression seal you used.

Impression seals are often used to make important marks or signatures on documents or letters. Back in the olden days, people used them to show that a letter or document was genuine or to show that it belonged to someone important, like a king or queen.

Impression seals can have different designs, like a noble family crest or the initials of a person. These designs make the seal unique to a specific person or group, so when the mark is made, people know who it came from.

So, imagine you have a special stamp that can make a special mark on clay or wax. You press it onto the soft stuff to make the mark, and this mark shows who the important person is or that the letter is real.
