Brazil is home to some of the world’s largest deposits, mostly found in the Amazon region. This makes it easy for Brazilian companies to produce red clay for export.
Clays in Latin America are classified into two major groups – samba clays and jequitibana clays. Samba clays are low-fired stoneware with quartz and feldspars as minor additives and phytoliths (the remains of plants) as a significant additive. Most common utensils are made from samba clay.
Jequitibana clays are high-fired porcelain clays with manganese oxide added at firing that gives them their beautiful metallic luster. They are also known as pirita or gourmet clays because of their unique color and luminosity.
India is another important producer of both samba and jequitibana clays. Although much of the Indian production is for local use in ceramics industries, there is an enormous potential for exporting this clay too.
China has been producing marble chips since the Han Dynasty (206 BC — AD 220). These chips were used by the Romans for insulating materials. Today, Chinese manufacturers can produce these chips up until 95% efficiency. With such efficiency, they could easily surpass Europe and North America in producing insulating material.
