Just about the time of the Arab conquests (about 600-700 AD), potters started to use metal-based glazes on their pots. So Islamic pottery looks very different from the Roman pottery that came before it.
West Asian potters invented this way of glazing pottery during the Roman Empire, but Roman potters didn’t use it very much. Glass glazes became much more popular during the early Abbasid empire, about 800 AD. That’s because the glass glaze gave potters a way to copy white Chinese porcelain. Traders were bringing Chinese porcelain west to sell in Baghdad. But it was very expensive. Local knockoffs in glazed pottery were cheaper.
Islamic potters then began to experiment with lots of different glazes. They painted one color over another, and sometimes fired the pottery more than once.
When the Mongols conquered Central Asia and China in the 1200s AD, there was even more trade between West Asia and China. Chinese pottery again became fashionable in West Asia, and a lot of West Asian pottery copied Chinese colors and patterns.
