Agate is a banded stone and belongs to the group of chalcedony quartz. He is one of the mineral classes of oxides. It is formed by successively deposited quartz layers in rock cavities in which even cavities can remain. The individual layers are formed by different quartz variants and foreign inclusions such as iron, chromium and manganese.

Get PriceThe superfluidity of water at 20–80°C in capillaries formed by quartz activated by grinding arises from quartz dissolution and from the interaction of the solution with the activated capillary surface. Superfluidity can be caused either by a decrease in the solution viscosity or by the sliding of the liquid along the capillary surface.
