I want to know the answer to the following question:
What did Egyptian artists grind to use to paint on the walls of tombs or on papyrus?
All the background I'm provided with is that "For painting on the walls of tombs or on papyrus, Egyptian artists used finely-ground malachite, mined in the west Sinai and the eastern desert- A paintbox with malachite pigment was found inside the tomb of King Tutankhamun.". Is that enough to answer the question?
Answer: yes
