How long did europeans try to find the composition of true hard-paste porcelain?

Europeans sought to discover the composition of true hard-paste porcelain for over a century after its introduction from China in the early 18th century. The quest began in the early 1700s, leading to significant breakthroughs in the 1710s and 1720s with the establishment of factories like Meissen in Germany. It wasn't until the mid-18th century that the complete formula for true hard-paste porcelain was reliably reproduced in Europe.
