This study intended to identify the ratio of alloy, metallographic examination and hardness on the bronze mirrors excavated in Korea and made the distribution chart of the main components according to each artifact and then tried to compare the ratio of artifacts with that of 鑑燧之齊of Zhouli Kaogongji(周禮, 考工記). Through this research, the components distribution of bronze covered a wide rage but it can be divided into 2~3 groups. When it is categorized into 3 groups, one is the bronze mirror with 70-80% of copper, 15-20% of tin and less than 5% of lead. Another is the bronze mirror with 20%-30% of tin which gives the white luster on metal and the high hardness. The other is the bronze mirror with 60-70% of copper and 15-20% of tin but it has more than 10-15% of lead which causes less luster and the low hardness. It contains less tin than 33%(50%) of tin from 鑑燧之齊 according to the old record Zhouli Kaogongji(周禮, 考工記) of Zhou Dynasty. In Korea the bronze mirror with tin of 鑑燧之齊was never found yet except the case of artifacts analyzed by non-destructive analysis.
