If you want to make a seal, place an iron mold on an iron plate to seal the characters densely. The iron mold is covered with a plate and held up to the fire. When the medicine is slightly melted, press a flat plate on its surface, and the characters will be as flat as a stone.

If you want to print, put an iron frame on the iron plate, and then arrange the characters densely in the iron frame. Once the iron frame is full, it becomes a printing plate, and bake it on the fire; when the iron plate is The medicine on it is slightly melted, and a flat plate is used to press it on top of the characters.
