This research aimed (1) to study the main element of thousand year old mud and types of color-giving substances from marigold flowers and (2) to study the causes of silk color change from dark yellow to dark green at Bankhokmuang, Chorakhemark Sub-district, Prakhonchai District, Buriram Province. Firstly, the researcher studied the element of the mud from Barai Prasat Muang Tam and Barai Kuti Ruesi, using EDXRF. Secondly, the researcher studied types of phytochemicals in marigold extract using HCl solution and NaOH solution. Finally, the researcher dyed the silk with marigold flower extract mixed with alum and dyed it with iron ion solution and the mud solution from both sources. The results showed that both muds had the highest amount of Fe2O3, 64.03% of Barai Prasat Muang Tam mud and 44.22% of Barai Kuti Ruesi mud. The coloring substance of marigold extract was flavonoids and had good water solubility. Then the researcher dyed the silk with marigold flower extract mixed with alum because alum contained Al3+ions. The silk was dark yellow. The silk was divided into three groups to be dyed again. The first group was dyed with 1,000 ppm iron ion solution. The second group was dyed with a solution of Barai Prasat Muang Tam mud. The third group was dyed with a solution of Barai Kuti Ruesi mud. All group color changed from dark yellow to dark green. Thus, iron ion solution and both of Barai mud solution were rich in iron ion. This complex compound could form with flavonoids which made golden yellow color turns dark green and sticks to silk threads. It was also water insolubility. The color was not faded. All groups had different shade values at the significance level of 0.05. GRAPHICAL ABSTRACT HIGHLIGHTS Study the main element of thousand year old mud Study area at at Bankhokmuang, Chorakhemark Sub-district, Prakhonchai District, Buriram Province. Causes the color of the silk thread to change from yellow to dark green
