 note = {About AMS dating for pottery samples, we reported that hard samples provided enough carbon for dating on last annual report. This study we analyzed ^<14>C ages for those hard samples. Organic materials sealed in the pottery when the pottery was formed will give the age when the pottery was manufactured. Pottery samples were ground and treated with AAA (acid-alkali-acid) to remove humic and fluvic soil acids. ^<14>C ages for the black pottery from the Philippines and fiber pottery from Japan; both contain organic carbon from grass inside. Carbon contents depend on preservation condition of the pottery samples, and we succeeded in obtaining reasonable ^<14>C ages using well-preserved samples. The ages of two pottery samples were from 2350 cal BP to 2095 cal BP, which showed that they are belonging to the Black Pottery I phase. The ages of five fiber pottery samples showed serially matched with archaeological chronology., タンデトロン加速器質量分析計業績報告 Summaries of Researches Using AMS 2003 (平成15)年度},
