What is the background of the revival of Spanish pottery in the late Middle Ages?

As early as the ancient Greek period, European pottery-making technology achieved brilliant results and formed an excellent tradition. Since then, although the pottery industry was once weak, there have been signs of revival since the late Middle Ages. This new development first appeared in Spain under Islamic rule. In 750, the Arabian Umayyad Dynasty perished, and a prince fled to Spain and established an Islamic country in its south. Since then, Spain has been ruled by Arabs for a long time, until the Christian Visigoths recovered their lost land in the third century, leaving only Grenada, a small country at the southern tip of Iberian Peninsula, in the hands of Arabs. 15 12 Spain got rid of the Arab rule and formed a unified kingdom of Spain. It was during nearly 800 years of foreign rule that the ceramic process design in Spain gradually developed from scratch. Around the 9th century, due to the prohibition of gold and silver wares, tin glazed painted pottery with metallic luster began to be popular in the Islamic world, and Spain was also affected. At that time, Christians lived in the northern part of Iberian Peninsula, and the Moors who believed in Islam lived in the south (the name of the Arabs who invaded Spain). As a result of the intersection and fusion of eastern and western cultures, a unique ceramic design style-"Spanish-Moore style" was born.
