Mysterious Mortar

One of the biggest mysteries surrounding the Great Pyramid is the mortar that was used to “glue” the blocks together. The truth is that to this day, no archeologist has been able to trace the origins of this mortar or the material that was used to make it. The only thing that researchers do know about it is its chemical composition. However, they have been unable to reproduce the composition. However, it is believed to be harder than the actual stone.
