イエロー鉄鉱石：ワサッチ山脈、ユタ州（ダスト・トゥ・ダスト）（卸売）

Ground it in a little water and the color really blooms—much richer than the dry powder suggests. I've been using it for a small earth pigment project and the fine grind saves me hours of prep time.

This stuff is surprisingly vibrant once you mix it with a binder—the natural yellow from the Wasatch Mountains gives a warm, earthy tone I didn’t expect. The fine grind from the mortar and pestle makes it blend easily into oil without clumping.

I love how fine the mortar and pestle grind gets this pigment—it blends so smoothly into my cold-process soap batter. The rich yellow from the Wasatch Mountains gives a natural, earthy color that’s exactly what I wanted.
