CHAPTER III.
QUARTERED OAK

In imitating quartered oak, or any other wood, it should always be borne in mind that it is the wood that we wish to imitate, and not somebody's idea of what it should be—for if we copy others, we become, as Byron says, "degenerate copyists of copies"—and the best thing that any beginner can do is to procure pieces of the real wood, study the various changes of grain and get the general character of the grains of each wood impressed upon his mind, then endeavor to reproduce them in his work; for the work will be judged by its general appearance, and not by the looks of any particular piece of work. After the champs or veins are wiped out with the rag, the spaces of combed work between the champs must be softened by a piece of rag folded three or four times and drawn over the combed spaces and toward the edges of the work previously wiped out with the rag. The edges of the champs may first be sharpened up by drawing the second joint of the forefinger against them. A fine comb is then waved over the spaces of open work and the whole panel blended lightly crosswise with the flat brush. Quartered oak can be imitated by combing the same as has been described, and letting the work dry before taking out the champs. When the work is dry, mix a weak solution of washing soda, and add a little dry umber to show where you touch the work, put on the champs with a fitch tool, let it stand a few minutes to soften the color, and then rub off with a soft rag, and it will be found that the graining-color is taken off to the ground-work, giving the same effect as if wiped out while the color was wet, only that the work looks cleaner. Work done in this way should be over-grained. The champs may also be put in in dark color over the dry combed work, and left so, as some veins of oak appear dark in certain lights. These dark veins may be imitated by combing the work the same as if going to use the rag to wipe out. Do not blend, but put in the veins with a small fitch tool or fresco liner dipped in some color from the bottom of your pot—not too dark—and immediately blend one way, lifting the edge of the color; after practice it will be found that a very good imitation of dark champs or veins is the result. Heart-work may be done in the same manner, but the combing should be done with a steel comb, the color for putting in the grains being but little darker than that with which the work is rubbed in. It is sometimes necessary to go over the whole with a fine steel comb. An occasional dark piece introduced among wiped work tends to relieve the sameness and looks more like the hardwoods; it also gives a better opportunity (where a job is not to be overgrained) to make distinct mitres and joints. This is very important and should never be forgotten. Be sure and have all joints cleanly cut, as nothing so much offends the eye as wavy or crooked joints. It is always better to make a distinction between the long stiles of a door and the adjoining cross rails. A common fault of the amateur grainer is his inability to make clean-cut divisions.

HEART GROWTH OAK, LIGHT.

The heart of oak—or, as it is sometimes called, "slash oak"—is usually done in the wet color, and is not combed previous to being wiped out with a rag. The outline of the work is first wiped out and the inner edges are softened with the rag. The edges of the work toward the side of the panel should be filled out either by hand or with a small rubber or leather comb covered with a thin piece of rag, being careful to follow close to the last line done by hand. This is an operation which if not carefully done will spoil the appearance of any job. When the panel or piece of work is grained, a coarse steel comb may judiciously be used, drawing it lightly over the heart-work and softening the whole lengthwise with the dry brush and toward all knotty places or turns in the wood. In case the work is to be overgrained, care must be taken not to soften the edges too much, as it will present too sunken an appearance. The plain grains are made with the comb; and if this part of the work is properly done, the effect is better than if it were full of strong grains.

When the work is to be overgrained (and good work cannot be done without), it may be overgrained when dry, in either oil or water color. If in oil (as we finish most outside doors, etc., in this vicinity instead of varnishing them), the same color may be used as for graining, or with the addition of a little more oil and drier, and darkened with umber if necessary. The check roller may first be used in water color, the work having previously been dampened, and, when the checks are dry, the whole gone over in oil. Or the checks may be put in in oil color after first overgraining in water color; this will necessitate oiling or varnishing when dry. The check roller is used to good advantage on hearts of oak, and the work should then be lightly blended lengthwise. In shading the champs the brush may be drawn through the shading-color, leaving the work streaked; then wipe off where the color covers the champs too deep. A similar effect is obtained by using a medium fine comb covered with a rag, the color being taken off in this way; this is for oil color. The blender drawn through water color, or a common oak overgrainer, gives the same effect for water color. It is better to go all over the work with a thin coat of color, as it looks raw without, and shading it in this way gives the depth that is otherwise unobtainable. Shadows are put in around knarly places, and touches added where needed, and the job is finished.

CHAPTER IV.
GRAINING OAK

Oak may be overgrained by using a very thin coating of asphaltum for the shading color; thin with oil and spirits.

Oak may be grained in distemper—that is, using beer or alcohol for a vehicle with the color, instead of oil. Good work can be done in this way, but not so quickly as in oil. A little sugar added to the beer makes it dry slower and work better than without it. If a tablespoonful of alcohol be added to a pint of beer, the work can be combed while wet almost as well as if in oil. First dampen the ground with a sponge wrung out in clean water, and then rub on the color the same as in oil; comb while wet (or use an overgrainer when dry) and blend lightly with a badger blender; then wipe out the veins or champs with a wet rag before the color dries, or afterward, as desired. A similar effect for light veins is obtained by using the fitch tool to put on the veins or champs and lifting off the color with the blender, thus leaving the champs light. For dark veins the work is put on with a fitch and left as put on. The heart-work may be done in the same manner, both for light and for dark pieces, but it cannot be done so successfully as if done in oil.

Of all the woods we have to imitate, I think oak is the most difficult, hence I have tried to explain the different ways in ordinary use of imitating it; and in closing I would say, Do not overdo your work. Most grainers put in more work—that is, showy grains—than would appear in the natural wood unless it were all selected. And remember that a nice piece of combed work is just as good a representation of oak as the majority of the heart-work often seen.

ASH

In graining ash in oil the colors necessary will be raw umber and raw sienna and a little Vandyke brown or black. Mix the color much the same as for oak, and the same tools can be used. After the color is rubbed in comb the places intended to be plain, and with the fitch tool or sash tool add lines, streaks, etc., if desired, using some color darkened with Vandyke brown or black, and blend lightly lengthwise with the dry brush. The heart-work or growth is represented by wiping out the color with a soft rag, the same way as for the heart of oak, but in ash the hearts are less complicated, and the points of the growth will be found to run more regular, and generally with a rounding edge instead of being serrated, as are the majority of oak-growths. The hearts of ash are also more narrow in proportion to the width of the board than are those of oak, and their imitation is much less difficult. Lightly stipple all wiped-out hearts with the dry brush. I think ash is one of the easiest of woods to imitate, as oak is one of the most difficult.

A very good imitation of a dark piece of heart-work may be done with a small fitch tool when the color is partially set. Sometimes the work is outlined roughly by lightly wiping off some of the color with a folded rag and describing the general direction of the grain to be followed by the fitch. The work is then put in with the fitch tool, and the edge of the color so put in is lifted with the blender, showing one edge light, and if carefully done, it looks well. The fitch tool is also employed to brighten the effects of the wiped-out hearts and to blend slightly. Where both means are used—that is, the fitch tool and the rag—in doing hearts of ash, the work presents a very woody appearance, and looks much better, if carefully done, than either method of doing heart-work does without the other.

Ash is greatly improved by being overgrained, but a great many of the dark streaks can be put in while the color is wet. Allowance can be made when it is intended to overgrain the work, and the dark places can be done more successfully when the color is dry by overgraining. The same color used to grain the work will do for overgraining it, or by adding a little black and thinning with spirits of turpentine and japan for inside work, and japan and oil for outside work where it is not to be varnished.

Ash may be grained in distemper by using stale beer or vinegar for thinners and the colors dry or ground in distemper. The effect of combing may be obtained by using an overgrainer. Where hearts are to be introduced, the work should be lightly stippled with a badger blender; and when dry, the wet rag or sponge may be used to wipe out the color preparatory to putting in the hearts with the fitch tool; this makes a fair job, and is the way followed by many in representing ash. The work looks fully as well, and I think cleaner, if the hearts are put in on the stippling without using a rag or sponge; do not stipple the work too heavily.

In matching Western ash a little blue sometimes helps to counteract the redness of the umber, and will be found to match the dull-gray shade often seen better than black, but ash is of so many varieties and colors as to allow the use of a wide range of colors.

In matching ash the filling of wood has to be taken into consideration. The filling used by the average painter is often anything but what it should be, and the beauty of many an ash door has been destroyed by the miserable attempts at filling often perpetrated by some ignorant painter. This is applicable also to other woods; but particularly to ash.
