There follows the book's longest chapter, "Less Common Species," which offers nearly a hundred pages of short accounts of minerals ranging from adamite and algodonite (a copper arsenide) through weloganite, whewellite, wulfenite, xonotlite, yugawaralite, zincite, zunyite (and many others even within the sequence WXYZ)--all considered in light of their potentials as ornamental materials.
Previous research results show that the red mud (Bauxsol[TM]) consisted of a mixture of minerals dominated by hematite, with abundant quartz, boehmite, gibbsite, brucite, calcite, sodalite, para-aluminohydrocalcite, hydrotalcite, and whewellite (McConchie and Clark 2000).
