Blue or Green: Minimized iron oxide, aka ferrous oxide, turns clay blue or eco-friendly. This coloration may possibly happen additional below waterlogged disorders.
A 23,five hundred periods magnified electron micrograph of smectite clay The defining mechanical house of clay is its plasticity when moist and its ability to harden when dried or fired. Clays exhibit a wide choice of drinking water content material in just which These are hugely plastic, from a minimum amount drinking water content (known as the plastic limit) where by the clay is simply moist sufficient to mould, to the greatest water information (called the liquid Restrict) where by the moulded clay is just dry enough to carry its shape.
Weathering of the same form of rock beneath alkaline conditions makes illite. Smectite kinds by weathering of igneous rock under alkaline ailments, although gibbsite sorts by powerful weathering of other clay minerals.[18]

describes soil’s capacity to stretch and maintain shapes with out breaking. Clays are more plastic—and so improved at Keeping their form—than other soils. That’s why they’re valuable for producing building materials like bricks and tiles.
