I am a great fan of Fayence. I will cover this in my next article in detail. The colors vary from green to blue in thousand different shades. So fascinating.
Yes, you are right - they had special tools to remove the brain through the nose or through a small hole in the backside of the head (near the neck). Tutankhamun, for example, had this hole in his skull, so the scientists first thought he suffered and died from a injury caused by murder or accident, until they found out that this was the "valve" to suck off the brain... brrrr :D
