The clay thus formed on the earth’s crust across the world differs in quality characteristics based on:
- the weathering process it went through
- the basic mineral the rock contained
- the climate condition differences of different geographical regions.
We wonder about this process and every geologist earnestly analyses the reasons behind it.
The clay in United States differs from the Clay in UK. The clay in India is different and so on. The origin for the Clay is the common Mother Earth. The common mineral is Kaolinite. However the quality characteristics differs from region to region, country to country, state to state, mines to mines, in the same mine – even depth to depth.
The whole confusing mystery behind this important ceramic raw material still contains numerous endless unanswered questions for ceramists and geologists similar to human life.
