Before closing the article on marbling, I will add a few words to the precautions to be observed while marbling. Before all else, see that the air in the room, where the marbling is to be done, is free of dust, as the falling dust, especially in drawn marbles will form many white spots, which spoil the effect of the marbling.

Cleanliness should always be observed, as the beauty of the marbles and their rapid production depend on it. Protect the size from dust by a lid, which you place on the vessel, and have a large soft sponge ready to remove the superfluous size after each immersion of the book, by which a rapid drying is obtained and the moisture is prohibited from impregnating the book.
