Seth Thomas marble mantel clock, ca. 1888.  Seth Thomas made a number of Belgian slate (black marble) mantel clocks, many shown on pages 581-588 of Ly’s Vol. 2 of Seth Thomas Clocks & Movements.  This one is not shown.  It is 13 inches tall and 20.5 inches wide.  There are some chips to the slate, particularly at the upper left corner, but the glossy polish makes them nearly invisible.  The gold paint in the incised patterns is very good, and there are two marbled accents on the front.  The two-part porcelain dial with ST logo has some chips but they aren’t terribly noticeable; it sits behind a beveled glass in a brass rococo sash.  The visible escapement has steel pallets.  The 8-day, time and half-hour strike is signed and running, striking on a cathedral gong.  Seth Thomas marble mantel clocks are surprisingly uncommon, and this one deserves a second look.  $150-$300.
