THE BROOM-CORN WHISK.
This whisk is made of soft broom-corn about 1 to 2 inches thick. The upper end is tightly bound with string or wire so that about 5 inches of straw protrude. These whisks are used in producing marble-edges.
THE BRISTLE BRUSH.
A bristle brush 3 inches long and from 2 to 2-1/2 inches thick is bound by a well waxed packing-thread about 1-1/4 inches from the top so that the bristles are open for a length of 1-3/4 inches. This brush is very well adapted for distributing the drops.
In marbling large lots of books, large broom-corn whisks are profitably used for throwing on the body color or sprinkling water. Being possessed of the above mentioned utensils which only are expensive at first, nothing is further necessary for the production of beautiful edges.
THE BOOK CLAMP.
The clamp is used to hold several books together which are to be immersed at the same time into the marbling trough. They are of iron entirely, are eccentrical in their movement and make a very quick handling and an easier holding of the books possible.
APPARATUS FOR THROWING ON COLORS.
For the purpose of producing nonpareil marble an equal distribution of color is desirable.
