If you like to buy some real hand painted egypt pictures on real papyrus I recommend Queen of Egypt Papyrus. They have a large collection of paintings and they also use to have demonstrations on how to create the papyrus. This shop you will find at: Abu El Houl St. Nazlet El Samman. I'm the one with a dark blue t-shirt and black cap at the photo listening carefully about how papyrus was made. I still have two beautiful paintings on my wall at home from this shop. I don't regret that I bought them.
The Papyrus Museum is usually rather forgotten in favor of the major museums, though it is a really interesting place, explaining everything about this ancient form of paper: how it was created, how it was written upon etc. You can also see some impressive examples of old papyrus documents - in a rather nice state of preservation.
Go to the Papyrus Institute and watch how they made the papyrus. First the plant is stripped.
The Papyrus Institue is a government approved shop making and selling authentic papyrus.
HOW IT IS MADE
First the outer covering of the papyrus stalk is removed and the interior is cut into thin stips. The strips are then hammered to remove the water. they are then soaked in water to reduce the sugar content from 20% to 10%. They are then arranged vertically and horizontally interlocking and kept pressed for 6 days under heavy iron presses. Periodically it is taken out to remove excess water.
Here you see the finished product. All of this took place at the Papyrus Institute. You can buy Egyptian art on papyrus at the Papyrus Institute.
