Anyone remember this famous case? What do you think of this article below? Im not sure it answers all the questions and perhaps disinfo?
Our expert Ean Harrison is a retired steel foundry quality control supervisor who worked in the Seattle area. Not only can he explain the origin of Bob White’s strange object, he once owned several of them and used them as garden ornaments. Harrison writes:
The object in question is made of accreted grinding residue. It forms in a manner similar to a common stalagmite when metal castings are “cleaned” on large stationary grinders. Rough castings need to have the parting line fins and gates smoothed to facilitate machining and reduce tool breakage. A typical stationary grinder in a foundry cleaning room used to hand clean castings up to 40 pounds may have a composite wheel 3 feet in diameter and 4 inches wide or larger. The casting is placed on a work guard just like the small grinder found in home workshops, and the piece is fed against the surface of the wheel, grinding off parting line fins, weld repairs, and gate bosses. The grinding dust is spewed downward into the wheel guard at a temperature near the melting point of the parent metal. When the metal dust and grinding wheel abrasive hit the bottom of the guard, the melted epoxy wheel binder glues the mixture together. Over time a stalagmite is slowly created from the bottom up, that fuses the parent metals into the characteristic form. Depending on the size of the machine, a stalagmite can easily grow to a length of 2 feet or more. Also, depending on the castings being ground, the composition of the stalagmite could be an exotic mix of stainless steel, manganese, mild steel, aluminum—in other words, a very puzzling metallurgical mix all combined in a seemingly impossible compound. But in reality it is merely a product of the melted grinding wheel binder. eventually the stalagmite grows high enough to block the opening at the base of the grinding guard. The housing must be opened, the stalagmite broken off, thrown away, recycled, used as a yard ornament, or reported as something tossed out of a UFO.
