Questions: The ancient Africans of Nok produced sculpture in what medium?

The answer is Terracotta.

Jade is a precious stone that has been used in various cultures for carving and jewelry, but it is not associated with the Nok culture of ancient Africa.

The Nok culture, which flourished in what is now Nigeria from around 1000 BCE to 300 CE, is renowned for its terracotta sculptures. These sculptures often depict human figures and animals and are some of the earliest examples of figurative art in sub-Saharan Africa.

While gold has been used in African art and jewelry, particularly in West African cultures such as the Ashanti, it is not the primary medium associated with Nok sculptures.

Glass was not a medium used by the Nok culture for their sculptures. Glassmaking techniques were not prevalent in the region during the time of the Nok civilization.
