The next thing he will make up is his scumble. This is composed of burnt umber, yellow ochre, drier, boiled oil, a little beat-up putty or whiting, and a small quantity of water. By mixing all this up together you produce something like a stained megilp, and may thin it with oil and water as you go on. A little of this goes a long way, as it has to be spread over very sparingly and equally.
Get a good specimen of real oak, well coursed with champs or ‘veins,’ and set it up before you where the light will fall best upon it; then, after rubbing down your grounded panel with fine sandpaper, and dusting it carefully, you will put a little ‘scumble’ upon it with your sash-tool, and spread that over equally and thinly with a larger brush until the panel is covered. Take your largest toothed comb, and trail it steadily down the panel from top to bottom, wiping the comb carefully after every passage. It is better to trail the large comb in straight lines, and afterwards use the smaller or finer toothed combs with a shake to produce wavy lines. When you have passed the combs over the panel in this way, first the coarse comb straight, next the medium size with a wave, and lastly, in portions, the finest size comb, your panel is ready for the artistic portion of the work.
Combing does not take long to learn if the worker is cleanly in his habits, but to make a natural and pleasing variety in ‘champing’ or veining takes a great deal of practice; indeed, unless the worker has artistic gifts, he will never be able to master this part of the work perfectly.
A young grainer ought to keep a sketch-book always in his pocket, and wherever he sees a fine bit of work, make a careful drawing with his pencil of it; he will thus be able to get variety in the markings of his wood. He ought also to practise constantly when he is at home on a panel with his thumb-nail at rat tails, so as to get dexterity and grace, because there is a vast amount of freehand drawing required in this portion of the work.
The first thing he has to study is the composition of that panel; the large markings come first. Here he may linger tenderly for a time with his rag-covered nail wiping out square, oblong, and round patches, and softening and half cleaning out parts with his narrowest and finest toothed comb, also rag-covered. At this portion of the work the true artist comes in with his manipulations, like the manipulations of the etching printer with his ink on the plate; and I am positive that if John Ruskin had but tried to copy a piece of real oak with the same tenderness and patience with which he has so often copied old masters, he would never have dared to decry the art of graining.
As in etching, perfect cleanliness and an unlimited supply of white, well-worn rags are indispensable to a grainer if he wishes to succeed in his art; yet, as the professional grainer is generally a dashing-looking fellow with artistically long and bushy tresses and Vandyke beard and moustachios, the maid-servant’s heart generally succumbs to his charms before even he has unpacked his traps, so that he is not at all likely to run short of clean rags during his campaign.
If any of my readers will take up and examine a piece of polished oak, they will be surprised to see what a multitude of strange devices there are in it; cabalistic signs and figures which are for ever varying as they shift about in the light; strong markings in places, with a crowd of slender flourishes trailing away from the bolder designs. These slender flourishes are vulgarly termed ‘rat-tails.’
Now, to comb a panel properly requires some practice and taste, but to be able to wipe out these rat-tails requires a great deal of practice and a greater degree of discretion, so as neither to crowd the panel nor make it appear meagre; the bolder figures with the softened parts require about as much real talent as is expended upon making an original sketch from nature, and a great deal more than would be wanted over the copying of an old master.
The comber and rat-tail draughtsman might easily qualify himself to copy an old master, but the adroit inventor of the bolder ‘champs,’ which occupy the centre of the panel, is already qualified to produce a monochrome direct from nature; if gifted with the colour-faculty, and if his power of making these ‘champs’ prove that he has mastered form, he might aspire to any height on the artistic ladder.
The panel being combed, grained, and cleaned, is left to dry, probably one or two days, as the weather chances to be, after which the grainer proceeds with the finishing off.
