It consists of four small color receptacles and apparatus from which protrude needles equi-distant from each other in the form of a rake.
The throwing of marble-colors at equal distances and in equally large drops on the size is made possible by it in a very certain and easy way and is even a good help to the inexperienced marbler in the production of even and exemplary edges. For the production of comb-marble on a large scale this apparatus is especially profitable as by using it much time is saved.
