Both anatase and brookite belong to the oxide minerals of titanium, which are two homogenous and polymorphic variants of rutile minerals. Anatase is a very rare mineral. Its composition often contains impurities such as ferric oxide and tantalum, niobium, tin, and manganese. It belongs to the tetragonal crystal system. Transparent to opaque, hardness is 5.5-6.0. […]
Realgar, also known as cockscomb stone, the English name is Realgar; orpiment, the English name is Orpiment or Auripigment, are two minerals that often coexist, algemeen bekend as “mandarin duck minerals.” Realgar is a short columnar crystal, a wedge-shaped pointed head, and a rhombus cross-section. It is also common in dense massive and granular aggregates, […]
