Associated minerals are quartz, limonite, azurite, malachite, cuprite, and other secondary copper minerals. Some of these minerals include cuprite, aragonite, wulfenite, malachite, azurite, and galena. Minerals include chalcocite, bornite and chalcopyrite, with associated malachite, azurite and cuprite. Blue pigments were made from minerals, especially lapis lazuli and azurite (. Copper may be precipitated as malachite Cu(CO)(OH) or azurite Cu(CO)(OH). Green eyeshadow came from malachite, while blue came from azurite. Notable examples include azurite, malachite, antlerite, and brochantite. Chalcopyrite can be oxidized to form malachite, azurite, and cuprite. Examples of such minerals are malachite (green) and azurite (blue). They also used less expensive green earth pigment, or mixed yellow ochre and blue azurite. The analysis identified lead white, azurite, lead-tin yellow, vermilion and yellow ochre. He painted the triptych with ochres, lead-tin-yellow, vermilion, carmine and azurite. Bosch's palette was rather limited with pigments including azurite, lead-tin yellow, vermilion and ochres. Pseudomorphs after more tabular or blocky azurite crystals also occur. He also painted with ochres, bone black and azurite.
