Water-Color Paint, of Which the following v is a specification.

on drying and, as'it dries comparatively j EDITH L. SNYDER, or Jonns'rowmrnnnsxnvnma' OIL WATER-COLOR PAINT.

No Drawing. y

To'aZZ uifiom it may concern 1 Be it known that I, EDITH L. SNYDER, a citizen of the United States, and a resident of Johnstown, in the county of Cambria.

and State of Pennsylvania, have. invented certain new and useful Improvements in Oll My invention relates to paint and has for its purpose the provision of a paint having a Wide range of usefulness containing oil and having many of the ad-' vantages of oil paint, while applicable by -means of water as a vehicle. Most water, color paints wash off readily so that attempting to paint over with another color a color already laid on Washes it ofi or mingles the two and "precludes obtaining effects and pursuing methods usual with oil paints.

An important characteristic ofmy paint, on the contrary, is that it is waterproof "rapidly, painting with one color over painting and for decorating and may. be used for all classes of work under these another without disturbing it presents no difficulty. Since this paint of mine is suited not only for rough work but also for thefinest Water color painting the importance of this will be appreciated since it makes possible the handling of water color painting in much the same .way as oil-painting and removes hamperinglimitations;

My paint is especially effectivefor scene heads except for sizing, that is, forshadow work, commonly lmown as dirty work, for f making the sketch and for finishing. My

paint asherein described is a paste which remains soft or moist in tubes and jars, and

to which Water may be added to make it sufliciently fluid to be applied with large brushes for the rougher work, or which may be applied by wetting small brushes as in fine water color work. It will be understood that I may use any desired pigment or-pigments just as in the usual water colors.

My invention thus consists of the oil water color paint described in the specification and set forth in the appended claims.

The ingredients I employ, in addition to the coloring matter, are glycerin, white. of egg, drying oil, copal varnish and glue. I am accustomed to use both linseed oil and pale, or'thin drying oil, of which also linseed oil is the"basis,.and liquid glue. The

vehicle of the copal varnish which I- have n Specification of Letters Patent.

oil '.water color Application filed August 10, 1917. Seri a1 No. 185 ,5141? employed it ee linseed oil and it is so light incolor as to be known as white copal varnish. This-makes it suitable for even the lightest colors, which may also be saidof the pale drying oil, It will be understood Patented Ja 13, 1920.

that I may use in lieu of any ofthe above ingredients any materials which are or may be found to be the equivalents thereof in, my composition. v

. The proportions of tlie various ingredients .which have proved to be suitable will be illustrated herein by examples, but-it of course be understood-by those familiar with this art, that proportions may be varied within a considerable rangewith difl'erent pigments and according to the special requlrements or individual taste of the user.. For instance, for a 'comparatlvely coarse heavy pigment, such 'as burnt sienna, more glycerin would be'required, while less would be needed for a vegetable pigment, such as rose madder. I v v Imake up my paint cold-and, if mixing it by hand, prefer to mix the pigmentin the form of apowder with glycerin to a thick paste and then add-each ingredient separately as in formula, If the mixing is done by machine'all the ingredients/may in the machine together. The paste, when the mixing is finished, should be cut short, that is when a small portion'is removed by'a palette knife, the out should be sharp andclean. The efiect of putting in too much of the white of egg is to makethe paste too thin and flulfy and to lessen its adhesive properties. Too much paste too thin.

'Without attempting to designate every function of each ingredient or precise re-= lation in the composition, I may state that my understanding of the part played by the e placed glycerin also makes the various ingredients in my paint is generally I speaking as follows -The glycerin. assists in making up the paint body. and keeps the composition soft or moist, preventing it from drying up and getting hard when used in paste form. The white of egg and theliquidglue-are adhesive binders. The white of egg makes the paste short and, since it works transparent, assists the glycerin efiectively. The linseed oil gives body and it, as wellas the drying oil, is a drier, the latter accelerating this effect, and both these oils play a part in making the paintwaterproof on drylng and in adapting it to uses and results whichthe paint waterproof on drying, and in addition to furnishing adhesive properties, the glue, and perhaps also the glycerin and the white of egg, assists in giving the composition' the characteristics Which enable'it to be used with wat'eras' the vehicle. If the paint willnot work with water more glue should beadded. v

It will be understood, of course, that my sired, although the formulas which I am about to give are for relatively small quantities which may be mixed by hand. It being obviously impossible in this specification to give for all the various pigments formulas exactly adapted to each, I, will confine myself :to two characteristic formulas: one for zinc white'and the othenfor burnt sienna. -.These are as follows:

' Zinc white.

zinc white 1 1b.. -Glycerinj 4 oz, White of egg 2 oz. Linseedoil 4: oz. -Pale or thin drying oil oz. Copal varnish 4 oz. V Liquid glue 4 oz.

-- Bu mt sienna.

Burnt sienna 1 lb. Glycerin L ;-10oz. White of egg 2 oz. Linseed oil .4. 4 oz.

-- Pale or thin drying oil 4 oz.

pCo'p-al varnish 4 oz.-

Liquid glue 45oz.

' As to these formulas," it. is'to be noted that the proportionate amounts given are those found to give the best results, but they are not to be understood as precluding reason-able variations. The zinc white for:

paint .may: be mixed inv any quantity. de'

" liquid glue, 'in a mula may be re arded as a-sort of standard, since it is applicable to. other pigments of substantially the same weight and fineness and may be modified in either. direction for lighter and finer o-r heavier and coarser pig ments. For. the former relatively-less and for the latter relatively more glycerin would be required: It is believed that one ifamili ar with'the art would, in the light of What has been sai d, have no diflioulty in determining the proper, proportions for-any given p1 ent. 1
