Metallographic microscopy, scanning electron microscopy, and x-ray energy dispersive microanalysis were used for analyzing 12 bronze objects, dating to ca. 1700-1400 BC, from Nizná Mysl'a, Slovak Republic, Czechoslovakia. The objects studied were made of tin bronze; the content of tin decreased during the period 1700-1400 BC. Bronze objects made during the period 1500-1400 BC contained arsenic and sulfur. Tin was found in 11 objects and its content varied from 5.0 to 39.9 percent mass. The content of arsenic found in four objects varied from 0.6 to 2.0 percent mass. Sulfur found in seven objects varied from 0.1 to 1.3 percent mass.
