I have watched Bien Foerster videos for several years now as his guide Yousef takes him a lot of interesting places off the beaten path and explains things about famous places not generally known.
In this video he explores the wondrous place called The Serepeum with amaing huge stone boxes.
In this episode he goes into detail about one particular box that displays different level of workmanship on the outside.
At the 10:00 minute mark he points out a clear liquid that has dried that apparently was used to polish the granite.
During one of Briens livestreams I asked him if they had ever had that clear liquid analyzed.
He replied 'it is Bitumen'.
I found that a bit odd because Bitumen is always found as a black viscous liquid. After pondering it for a while the only thing I could conclude was this has to be a very concentrated version of it.
