Sample of biotite Schist, from the shear zone in the Beitbridge Complex in South Africa. Schist is metamorphic rock caused by pressure during medium grade metamorphism.

A molecular model of Bisphenol A or BPA. It is a common building block in the production of many epoxy resins and plastics including polycarbonate plastic. As such it is present in a huge range of food packaging and household products. There are now concerns about its health effects, particularly its effect on children, infants and fetuses. Isolated on white.

Navat is a special sugar that crystallizes in a special way. It is served for tea, sometimes it is replaced by simple sugar or caramel candy. Navat is made from condensed sugar syrup or from grape juice. Special spices are added to it. The boiling syrup is poured into huge cauldrons with strands stretched horizontally. Around these threads the crystals of sugar are formed. Navat can be of different colors: from whitish to saturated brown. This Uzbek sweet product is added to tea or simply sucked in the mouth.

Agate is a microcrystalline variety of quartz, chiefly chalcedony, cryptocrystalline form of silica. Although agates may be found in various kinds of rock, they are classically associated with volcanic rocks but can be common in certain metamorphic rocks. Most agates occur as nodules in volcanic rocks or ancient lavas where they represent cavities originally produced by the disengagement of volatiles in the molten mass which were then filled, wholly by siliceous matter deposited in regular layers upon the walls.
