Granular cast
Urinary casts are cylindrical structures produced by the kidney and present in the urine in certain disease states. They form in the distal convoluted tubule and collecting ducts of nephrons, then dislodge and pass into the urine, where they can be detected by microscopy.
They form via precipitation of Tamm-Horsfall mucoprotein which is secreted by renal tubule cells, and sometimes also by albumin in conditions of proteinuria. Cast formation is pronounced in environments favoring protein denaturation and precipitation (low flow, concentrated salts, low pH). Tamm-Horsfall protein is particularly susceptible to precipitation in these conditions.
Casts were first described by Henry Bence Jones (1813-1873).
As reflected in their cylindrical form, casts are generated in the small distal convoluted tubules and collecting ducts of the kidney, and generally maintain their shape and composition as they pass through the urinary system. Although the most common forms are benign, others indicate disease. All rely on the inclusion or adhesion of various elements on a mucoprotein base—the hyaline cast. "Cast" itself merely describes the shape, so an adjective is added to describe the composition of the cast. Various casts found in urine sediment may be classified as follows.

Granular casts are the second-most common type of cast and they are the result either from the breakdown of cellular casts or the inclusion of aggregates of plasma proteins or immunoglobulin light chains. Depending on the size of inclusions, Granular casts can be classified as fine or coarse, though the distinction has no diagnostic significance.

Another Fake Casting (mouthpiece)
http://cgi.ebay.com/B-D-Dukoff-Hollywood-tenor-mouthpiece-/180526421936?cmd=ViewItem&pt=LH_DefaultDomain_146&hash=item2a083697b0 ..And here is another fake casting of a B.D. Hollywood tenor piece. It is called an "oddball" DUkoff, and has been refaced by BP, but is actually a fake, probably sandcasting and not at all an original blank. Notice the little holes all over the surface metal. In this case this is not pitting from age, but original due to the Granular casting surface.
