WI porcelain was developed earlier in Europe?

This is a fairly minor POD but which for some reason started to interest me. IOTL modern European porcelain was developed presumably by Ehrenfried Walther von Tschirnhaus in 1708 in Saxony. (There had been some earlier production but quality and quantity hadn't been yet so great.) So what if some merchant interested in chemistry (say in France) was able to create good quality porcelain two hundred years earlier in 1508?
 
Much less imports of fine porcelain from the Far East, particularly Japan. Might have some economic effects there.

Europe to. If porcelain was produced in southern France f.x. there´s a lot of american gold and silver going that way.
 
The design of porcelain would also have been more european. Hardly a chance for the onion pattern (copying ming dynasty blue and white porcelain) to become as dominant as it did in OTL. Instead renaissance style designs like they were popular on majolica plates of the late 15th and 16th century would be much more widespread.

Assuming large scale production started in Southern France and took sometime to spread other countries, Southern France would be somewhat richer than they were IOTL. Maybe this would help some other industries in that area too?

That's an interesting cultural effect. Chinese design may not be as prestigious here as it was to become later.
