Add bentonite to the clay body.

There are different minerals present in each clay body. Red clay typically has a higher iron content than grey clay.
Its red because of the minerals that mix together to form that color :)
Terra Cotta Clay with Grog 25lb Terra cotta is a standard in the field of pottery and ceramics. A few basic variations in this formula, such as bentonite for plasticity and a fine mesh time-tested grog, are only two of the inert qualities. These unique qualities are found only in standard clay mines terra cotta.
no.
Add bentonite to the clay body
the plasticity index decreases with increase in percent of fly ash because the hydraulic conductivity ( k) goes on increase
the answer is plastics! -------------- Ex.: plasticine, clay, soils, bread, butter, etc.

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.
yes, in that it has no plasticity.
Clay comes in the colours from a dull grey to an orangey red, this is because these are natural colours and clay would only come in natural colours in old greece, and Clays exhibit plasticity when mixed with water in certain proportions. The person who wrote the other answer is right but there are lots more facts about clay and if you type in to google clay facts, then lots of really good things will come up.

Clay minerals are microscopic, platy particles, and which have variable plasticity when mixed with water. Some of the major groups of clays include types called illites, kandites, smectites, and vermiculites. They are mostly hydrous silicates.

How plastic a clay is determines how far and how much it can be stretched. For example you would want a clay with a some what height elasticity for wheel thrown pieces but, maybe not so much for sculpture. If a clays elasticity is not high it will crack or break when you try to stretch it
