DUTCH MANUFACTORIES OF PORCELAIN.

What manufactories of porcelain were established in Holland?

When, by whom, and at what places were they established, and when did they cease to exist?

What marks were used to indicate the different manufactories, and had the manufactures any distinctive character?

The mark M. O. L. is frequently found on Dutch porcelain, and occasionally the word Amstel; what is the meaning of these marks, and when were they employed?

A stork is also found as a mark on Dutch porcelain, which is said to have been made at the Hague. Is this correct? and if so, what is the history of the manufactory?

Was any porcelain made at Arnheim? and if so, what was the distinguishing mark?
