What was the material for writing in Egypt and Mesopotamia?

Cuneiform was used in Mesopotamia. On a clay tablet, when it was damp, the necessary signs were applied with a wooden stick. The wand was sharpened in the shape of a wedge. Clay impressions were wedge-shaped. Such a plate was dried in the sun and kept a record. If necessary, the clay was moistened and the record was corrected. The corrections often concerned the amount owed by the debtor slaves. They worked and the amount of debt decreased.

In Egypt, writing on clay tablets was also used. This was due to the difficulty of making papyrus. It is papyrus that is considered characteristic of Ancient Egypt. For its manufacture, they took parts of the stem of a certain plant and laid them tightly on a plane along. We applied glue and laid the next layer across. The sheet was beaten off and sanded. They wrote with a reed stick. The paint was made from carbon black or minerals.
