   DH> Excellent question - turns out that the process was sort

   DH> ..patent leather is a fine grain leather that is treated   
   DH> to  give  it  a glossy appearance. An early reference to   
   DH> patent leather is in the  1793  British  periodical  The   
   DH> Bee,  or  Literary Weekly Intelligencer, which notes, in   
   DH> an article entitled "Hand's  patent  leather",  that  "a   
   DH> gentleman  of  the name of Hand" in Birmingham, England,   
   DH> obtained a patent for preparing flexible leather  having   
   DH> a  glaze  and polish that renders it impervious to water   
   DH> and need only be wiped with a sponge to  restore  it  to   
   DH> its original luster.   
      
   By  the  way,  when  I  treated  one pair of my shoes with a   
   solution  of  beeswax  and  propolis  in  turpentine,   they   
   acquired  the  properties  patent leather.  This solution is   
   made in Crimea as a universal  protective  impregnation  and   
   coating  for metal, wood, and leather.  The turpentine draws   
   the components deep (0.5-1.0 mm) into the  material  through   
   its pores, leaving a matte-glossy coat on the surface.
