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 clay
secondry clay:- 2ndry clay are transported and formed, so more impurities, fine particles, more humic,higher plasticity and shrinkage.
Primary clay is formed directly from the weathering of rocks, while secondary clay is formed from the alteration of preexisting minerals. Primary clay is typically pure and lacks impurities, while secondary clay often contains impurities due to its formation process. Primary clay is usually found in close proximity to its source rock, while secondary clay can be found at varying distances from its source.

What is the difference between silt and clay?
Silt is larger in particle size than clay and feels gritty when dry, while clay is finer in particle size and feels sticky when wet. Silt is more fertile than clay and drains better, while clay holds more water and nutrients.
What is the difference between loamy and clay soil?
Clay soil has smaller particles than loamy soil, making it dense and easily compacted. Loamy soil is a mixture of sand, silt, and clay, and is considered the ideal soil type for gardening because it has good drainage and nutrient retention.
How does clay turn into limestone?
Clay can turn into limestone through a process called diagenesis, where the clay particles are subjected to compaction and cementation, forming a new rock material. Over time, the minerals in the clay are altered and precipitate out to form calcium carbonate, which is the primary mineral in limestone.
What is the difference between loam and clay?
Loam is a soil type that is a mixture of sand, silt, and clay, with good drainage and nutrient retention. Clay, on the other hand, is a type of soil with very fine particles that compact easily, has poor drainage, and tends to hold nutrients tightly. Clay soil is often denser and heavier than loam soil.
Does sandy soil or clay soil have bigger pore spaces?
Sandy soil typically has larger pore spaces compared to clay soil. This is because clay particles are much smaller and more tightly packed together, reducing the size of the pore spaces between them. This difference in pore space influences factors like water drainage, aeration, and root penetration in the soil.
What type of clay is terracota what colour is it and is it a secondary or primary clay?
Terracota is a type of earthenware. It is usually reddish brown from Iron oxide inclusion. Earthenware is a secondary clay.
How do you differentiate between primary and secondary minerals?
Primary minerals are original, directly formed during the crystallization of molten rock or magma, such as quartz and feldspar. Secondary minerals form through weathering and alteration of primary minerals, usually in the presence of water and air, such as clay minerals and various oxides.
Is there a difference in between extruded clay and modeling clay?
Why yes there is. An extruded clay is something pushed out by a machine and modeling clay is handled by man.
How is the clay formed?
Its primary mineral is kaolinite; clay may be generally described as 40% aluminum oxide, 46% silicon oxide, and 14% water. There are two types of clays, primary and secondary. Primary clay is found in the same place as the rock from which it is derived-it has not been transported by water or glacier and thus has not mixed with other forms of sediment. Primary clay is heavy, dense, and pure. Secondary or sedimentary clay is formed of lighter sediment that is carried farther in water and deposited. This secondary clay, a mixture of sediment, is finer and lighter than primary clay. Varying additives give the clay different characteristics. Clay comes to a production potter in one of two forms-as a powder to which water must be added, or with water already added. Large factories purchase the clays in huge quantities as dry materials, making up the clay batch as needed each day.* http://www.madehow.com/Volume-4/Pottery.html
What is the difference between brown and white clay?
One is brown and the other is white.

What is a primary clay?
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.
Whats the difference between a fairy and a golem?
The difference is a Golem is created by clay and magic a Fairy is organic born from other fairies.
What is the difference between clay and shale?
Clay is a type of fine-grained natural soil material that is composed of mineral particles smaller than silt. Shale is a fine-grained sedimentary rock that is formed from the compaction of clay, silt, or mud over time. Essentially, shale is the hardened form of clay.
Difference between pet bottles brick and clay brick?
PET bottles bricks are made from recycled plastic bottles, offering a more sustainable alternative to traditional clay bricks. They are lighter, more flexible, and have better insulating properties. Clay bricks are made of natural materials such as clay and shale, they are denser and more structurally sound, commonly used in construction for their durability.
What is the difference between plasticine and Play-Doh.?
The main difference is that plastiscine is derived from clay and is oil based. Play doh is water based, and is totally edible.
