I was there to study a casing stone from the pyramids of Giza in Egypt. The casing stones have an angled front face that formed the outer surface of the pyramid. The front is triangular in form when viewed from the side, as opposed to the inner blocks which were left roughly hewn and were approximately cuboid.ur Edinburgh casing stone, therefore, is probably not just a Great Pyramid casing stone, it is probably an upper level Great Pyramid casing stone, from up near the summit of this incredible monument, 146 meters high when completed.
Because the sand mold must be destroyed in order to remove the part, called the casting, sand casting typically has a low production rate. The sand casting process involves the use of a furnace, metal, pattern, and sand mold.The metal is melted in the furnace and then ladled and poured into the cavity of the sand mold, which is formed by the pattern. The sand mold separates along a parting line and the solidified casting can be removed.ecause the sand mold must be destroyed in order to remove the part, called the casting, sand casting typically has a low production rate.
