142. There is no need of special brushes or tools for any of the operations about to be described, and the ones described as useful for the imitation of wood by graining will more than suffice as but few brushes are needed. For laying the grounds, some of the larger flat ones and some smaller flat ones to lay in colors in smaller groups, and dry ones to blend them. Some fitches or small bristle artists’ brushes and some camel’s hair pencils with a few wing and tail feathers for putting in some of the finer veins, and badger blenders are about all the tools needed.

143. As to material, white lead and zinc white will form the bulk of it, as it is used either as a base or by itself in all the marbles that will be described, with, of course, the exception of the black marbles. As there are so many colors used in imitating marbles, the whole list may be of use at some time or other, and it will not be necessary to name them all over at this time, as under each marble will be given the ones needed. Light varnishes are required in order to give the finished marble a uniform appearance and as a protection. This is the hardest part of all to procure, as the stronger ones are not fit to use over white or even upon some of the darker ones having white veins, turning them yellowish. Damar varnish is forced upon the marbler, so there is little wonder if many prefer to leave the work as it is without varnishing.

All the above applies to oil color marbling only as work done in distemper is never varnished. The colors needed in water color marbling are the same as for oil work, only they must of course be in the dry state.

144. The walls of halls are sometimes done in imitation of marble slabs, and one is then required to scaffold for it in order to reach them. As directions were given how to reach the walls and ceilings in Vol. II, or “Interior Painting,” the student is referred to that for fuller details. For most work good step ladders will be found best, as they permit the work to be done with more comfort, the operator climbing up or down as needed without having to reach up or bend down too much.
