   The other is with the incorporation of water molecules directly into the crystalline structure of a new mineral, [1] as with the hydration of feldspars to clay minerals, garnet to chlorite, or kyanite to muscovite. [citation needed] Mineral hydration is also a process in the regolith that results in conversion of silicate minerals into clay ...

3. Vitrified clay pipe - Wikipedia

   en.wikipedia.org/wiki/Vitrified_clay_pipe

   Vitrified clay pipe (VCP) is pipe made from a blend of clay and shale that has been subjected to high temperature to achieve vitrification, which results in a hard, inert ceramic. VCP is commonly used in gravity sewer collection mains because of its long life and resistance to almost all domestic and industrial sewage , particularly the ...

   When sucrose is cooled slowly it results in crystal sugar (or rock candy), but when cooled rapidly it can form syrupy cotton candy (candyfloss).. Vitrification can also occur in a liquid such as water, usually through very rapid cooling or the introduction of agents that suppress the formation of ice crystals.

   The earliest type consisted of a "u" shaped trough onto which a flat lid was placed. Later the extruded clay pipe was developed. These are still used. These can be laid in an excavated trench, or a horizontal hole is formed in the ground using a mole plough and the pipes are forced in by means of a hand or mechanical press. By this means, heavy ...
