Abstract
The purpose of this study was to investigate main ingredients of Hwangtoh (Korean yellow ochre), especially ferric oxide $(Fe_{2}O_{3})$ content. In this study, X-ray fluorescence spectrophotometry was employed to analyze the ingredients of Hwangtoh. The ferric oxide $(Fe_{2}O_{3})$ contents of Hwangtoh from Hwa Sun, Ham An, Chil Gok, Sun Chun, Ha Dong, San Chung, Go Chang, Kim Che and Jeong Eup were 1.5, 5.66, 11.76, 6.63, 2.74, 11.4, 4.84, 7.21 and 6.23%, respectively. Based on the above results, any Hwangtoh sample didn't meet the ferric oxide $(Fe_{2}O_{3})$ content criterion.
