= China Clays = China Clays - What are the Differences?Ceramics? Stoneware? China? Bone China? The properties of clays include plasticity, shrinkage under firing and under air drying, fineness of grain, color after firing, hardness, cohesion, and capacity of the surface to take decoration. From these properties clays are divided into classes or groups; products are generally made from mixtures of clays and other substances. The purest clays are the china clays or kaolins. "Ball clay" is a name for a group of plastic, high-temperature clays used with other clays to improve their plasticity and to increase their strength.* http://www.he-and-she.com/english-china/china-clay.html
There is a wide variety of modelling clays: Mineral clays, are refined forms of the clay you may find in the ground, and are dense over two kg/lPolymer clays are much lighter, about 1 kg/land paper based clays can be very light, depending on their dryness.If you have an actual sample the best thing to do would be to measure it.
Once fired and hardened neither polymer clays (Fimo, Sculpey) or natural clays are biodegradable, as witness the many pottery remains still solid after thousands of years.
Yes, certain types of clay can dissolve in water. These types of clays are not fired, non oil based clays, but natural and air dried clays.

Primary clay is clay that has not been moved from its original source location. It is typically found close to where it was formed and has high mineral content. Primary clays are considered pure and are valued for their plasticity in pottery making.
To filter impurities out of the blood.
primary clay:- once formed from the parent rock deposited at origin, so less impurities,coarse particles,less humic acid , low plasticity& low shrinkage than 2ndry claysecondry clay:- 2ndry clay are transported and formed, so more impurities, fine particles, more humic,higher plasticity and shrinkage.
Flood plain clays are considered "massive," a term used to describe clays without a bedform, which is the arrangement of particles of sediment. Clays found in lakes are "laminate," whcih means that they are usuallypretty uniformly thick, and lay flat on the bottom of a body of still water with little to no current.
The mineral commonly found in many clays is kaolinite. It is a type of clay mineral that is formed from the weathering of aluminum silicate minerals.
Clays are called exactly that - clays. Sometimes they will be referred to as targets or clay pidgeons, but I am not aware of any other commonly used terms for clays.
The impurities found on the surface of magnesium in the formula of magnesium oxide are often magnesium hydroxide and magnesium carbonate. These impurities can form due to exposure to air and moisture, which leads to reactions with carbon dioxide and water in the environment.
