Anthony,

To my knowledge no specific scientific study has been accomplished or published on the composite character of the coffer granite compared to the chamber granite. However there are plenty of photographs (old and new) of the coffer in the chamber, close ups of the coffer granite and the wall granite to support the claim visually. The best example can be seen in the photo of the Edgar party sitting on the back edge of the coffer, there you can see the grain shift is not mistaken. Additionally, I spent more than hour or so last year personally examining and comparing the coffer granite (its color, grain and composition) to the granite used in the chamber. Overall the coffer has more and deeper black color stone within its composite than the wall stones and the lighter color (red-flake) particles are significantly larger than those found in the wall stone. The overall grain of the stone used for the coffer is compositely looser than the granite used in the chamber.

Best Regards,
