Yellow “Silt” Clay – This Yellow Clay derives its earthy yellow color from iron oxides naturally present in the clay. Because of its color, the clay may stain fabric. This clay is fantastic as a mask base or in a cleansing paste. In CP soap, it is a lovely yellow (though as it is a clay, tends to absorb the water in your CP recipe so don’t use any clay for color if discounting your water).
