Nubian Pyramid - Special Water Prep

[DoctorWho]

Ra makes note of how the pyramid needs to be correctly proportioned and not made of base metal.

also these are cool. Ra describes how the pyramidions were made of gold which is a metal but not base metal. I recently read some Egyptian books indicating what Ra said about pyramid capstones being plated with gold was correct.

That's right! thanks for replying. 

There is certainly something special about gold.
