How clay works?
 |
All clays have basically the same physical properties that vary in intensity depending on the molecular composition and structure. The molecular composition, more speciffically the mineral components, will also give a specific color to the clay (See our different clay colors). Some clays will appear more interesting for therapeutic purposes when others will have properties more appreciated in construction (bentonite for concrete), potery, porcelaine, etc...
When we study clay powder samples under a microscope, each grains looks like layers stacked up one on to the other (like a pile of plates). This layered structure gives the plastic properties of clay and its ability to cover a surface. Layers, when hydrated, can slide one on to the others, allowing them to expend or retract themselves. This plastic ability stops as soon as the clay dries.
The mineral composition of the layers will create the specific polarity to the clay. (positive or negative charge). Basically, to make things simple and understanble, the charge of the layers themselves is negative when the charge in the space between each layer is positive.
This specific polarity, a balance between negative and positive charges, gives the binding (fixing) properties of the clay, that are also known as ABsorption and ADsorption properties. The ABsorption property is comparable to a sponge; clay can capture in its own cellullar structure molecules and substances. This explains its power in absorbing liquids and grease, and neutralizing odors. Clay can also attract molecules or organisms just like a magnet (ADsorption property). The substances in this case will stick outside of the structure. This property explains its capacity in neutralizing microbes, bacteria, viruses, dead cells and other substances like chemicals for example.
Depending on the size of the molecule, the attraction will be done on 3 different levels:
1) Simple ions will be captured inside the layers themselves
3) Macromolecules (big molecules and substances) will stay at the periphery of the layers.
Remember that the ionic charge of clay is very fragile and is easily neutralized by any artificial treatments (heat, washing, irradition, aseptization, etc). Without this specific ionic charge, clay looses its basic properties. This the reason why you should choose a living clay (raw, virgin, sun-dried).
This is the fixing properties that make clays interesting on the therapeutic level. But as we have mentioned earlier, not all clays can be used for this purpose since, depending on their mineral composition and structure, some clays are very toxic for the body. For more safetiness, look for pharmaceutical grade and food grade certified. To benefit from the optimal properties of clay, always look for living clay - raw, sun-dried, non ionized, unprocessed and free of any additives,which is the quality that Argiletz provides for over 50 years. << back to top
