LESSONS III. AND IV.
TOOLS USED IN GRAINING AND MARBLING.
10. Brushes. The brushes required for the laying on of the “ground colors” are the same as would be used for similar work in interior painting. A good oval 6-0 varnish makes a fine tool for the purpose. Some prefer the flat brush for laying on color; any good 3-inch flat brush that will lay color smoothly.
11. For “rubbing” in the graining colors in oil some use half worn-out, flat brushes—others again prefer the round or oval, and again some rubbers-in use a brush that has been well broke in but not worn much. It is largely a question of habit. If the “megilp” is just right, the rubber-in can take almost any kind of a brush and rub out well with it, but the advice of using an old worn-out brush which is seen in some of the old-time books on graining should not be followed too implicitly. A half-worn brush will probably suit more “rubbers-in” than any other extremes. None of the above need illustrating as these brushes are in constant use in all paint shops. Besides a number of kinds are shown in Vols. I and II of the red series.
