A simulated granite and its preparations are provided. The granite comprises (A) about 35 to 95% by volume of a matrix consisting essentially of (1) at least 34% by volume of polymer, preferably predominantly an acrylic polymer, having a refractive index (n.sub.D) between 1.4 and 1.65 and (2) about 1 to 50% by volume of at least one microscopic filler having an amorphous or mean crystalline axial refractive index between 1.4 and 1.65, (B) about 0.1 to 50% by volume of macroscopic opaque particle...

A wall bracket for the support of a shelf, a table or a bench is fastened to a lipped box channel that is vertically positioned with its open slit towards the shelf; it is held in the channel by friction forces only and can be readily moved up and down and held at any desired height of the channel. The bracket end which is inserted into the channel through its slit has a horizontal rectangular top portion smaller than the channel inside, but wider than the slit, and is connected to the bracket b...

A chromium or chromium alloy plating system and material are disclosed. The chromium is supplied by an aqueous equilibrated solution of a chromium (III) thiocyanate complex. A buffer material which also supplies one of the ligands to the chromium complex is provided. The buffer material is selected from amino acids, peptides, formates, acetates and hypophosphites.
