Answer:
The walls of King Tutankhamun's tomb are primarily made of limestone, a sedimentary rock composed of calcium carbonate.
However, the walls aren't just bare limestone. They're decorated with several layers, including:
A plaster layer: This smooth layer provided a canvas for the artists to paint on. It was made from a mixture of mud, straw, and gypsum.
Paintings: These vibrant murals depict scenes from Tutankhamun's life, religious rituals,and mythology. They were created using mineral pigments mixed with a binding agent.
Reliefs: These raised sculptures portray important figures and events in the king's life.They were carved directly into the limestone.
