Loop & Dart Glass Pattern
Loop & Dart with Round Ornament was the second major pattern introduced by the Portland Glass Co. (Maine), having been patented by Plant Superintendent William O. Davis in 1869. The company had a very short life, 1864 to 1874, so this pattern is relatively rare. Loop & Dart with Round Ornament features a row of spear points alternating with oval loops suspended from a rim band with raised round knobs, and a stippled background below the rim band. At least two other glassworks produced similar Loop & Dart pattern pressed glass, possibly Boston & Sandwich Glass Co. and an unidentified Pittsburgh, PA glassmaker.
