Calcium carbonate 胡粉(gofun): A white powder that can occur in three crystalline forms: Calcite (hexagonal-rhombohedral), Aragonite (orthorhombic) and vaterite. Calcium carbonate occurs naturally in many forms such as Chalk, Limestone, Marble and sea shells. In Japan, the source is sea shells. (Before the 15c., the term gofun has been used to also indicate lead white but today it is exclusively used for calcium carbonate.-not relevant?)

Analysis
Excitation Emission Matrix (EEM) spectroscopy can easily identify the organic reds: safflower, madder, and sappanwood. Madder fluoresces brightly under UVA radiation and produces a unique EEM pattern that helps differentiate it from safflower, which also fluoresces.
