What did the ancient Egyptians write on?

The ancient Egyptians wrote on papyri.
Papyrus is a writing material that was widespread in Ancient Egypt from the 3rd millennium BC. For the manufacture of papyrus, the plant of the same name was used, which grew along the banks of the Nile. The oldest samples of papyri found during excavations in Egypt date from the period of the 1st dynasty. The technology of making papyrus was reconstructed in the 20th century; today papyri are used in the tourism sector as souvenirs.
