E. 8. SMITH PROCESS FOR PRODUCING CLOUD EFFECTS IN ENAMELS May 2, 1933.-

Filed Nov. 23. 1932 Ear/e 5. fimith INVEN-TOR ATTORNEY Patented May 2, 1933 UNITED STAES PATET OFFICE EARLE S. SIVIITH, OF TOLEDO, OHIO, ASSIGNOE TO THE TOLEDO PORCELAIN ENAMEL PRODUCTS COMPANY, OF TOLEDO, OHIO, A CORPORATION OF OHIO ZPROCESS FOR PRODUCING CLOUD EFFECTS IN ENAMELS Application filed November as, 1932. Serial No. 643,970.

This invention relates to processes for producing cloud effects in enamels and particularly to a process for producing effects having the appearance of clouds formed in light wisps through which a sky-like background is visible, thus simulating the effect of a cirrus clouded sky.

Another object is the provision of a process for producing light cloud effects in which cloud wisps are given a slightly fibrous mackerel sky effect.

Other objects and advantages will be apparent from the following description, in which reference is had to the accompanying drawing in which Figure I illustrates the appearance of a panel upon which my enameling process has been partially carried out and Figure II illustrates the panel after a succeeding step of the process has been applied thereto. Owing to the impracticability of reproducing the beauty of the final effect, no attempt has been made to illustrate the panel after the final step.

In carrying out the process of my invention, a metal, preferably iron or steel, article or piece to be enameled, aft-er proper cleaning is dipped, sprayed or otherwise covered with a first or so-called ground coat of vitreous enamel frit the color of which is not important so far as ultimate appearance is concerned. If the ground coat is applied by a wetprocess it is then thoroughly dried. The ground coat of vitreous enamel is next fused to the metal in an enameling furnace.

When the article has cooled it is sprayed or dipped to coat it solidly with enamel frit to form a background of proper color, such, for example, as sky blue.

While the coat of solid color is still wet it is speckled, by means of a splatter gun or otherwise, with numerous small spots of enamel of another color, giving it an appearance resembling that of the panel illustrated in Figure I of the drawing. The spots, however, instead of being black on a white background, may be white on a blue background, or any other combination of colors may be selected.

While the spattered surface is still wet it is brushed in one direction with a wire or stifl bristle brush or comb, the wires, bristles or teeth of which are spaced apart so that the surface of the wet enamel is furrowed and the colors are streaked into each other; the surface thus taking on the appearance illustreated in Figure II of the drawing.

While the outer coating is still wet and somewhat fiu'id the article is arred or jolted. This results in smoothing out the furrows left by the brushing or combing operation and giving the streaked color a light, fluffy, delicate appearance, with the fibrous structpre and feather-like form of a cirrus clouded s ry.

The coating is then thoroughly dried and finally fused to the ground coat, the fusing operation further enhancing the beauty of the clouded coating. 7

Although I have illustrated the steps of my process in black and white and have described the process as utilizing blue and white, the effect may be obtained with any selected colors. The embodiment of my invention herein described is tobe regarded as illustrative only, and it is to be understood that the invention is susceptible to variation, modification and change within the spirit and scope of the subjoined claims.

Having described my invention, I claim:

1. In an enameling process, the steps of applying to a surface a solid wet coat of vitreous enamel frit of one color, speckling said coat with wet vitreous enamel frit of another color, streaking said coat by a brushing operation, jarring said coat to produce a cirrus clouded effect, drying, and fusing said coat to said surface.

2. In an enameling process, the steps of applying to a surface a ground coat, fusing said ground coat thereto, applying to said ground coat a solid wet coat of vitreous enamel frit of one color, speckling said coat with wet vitreous enamel frit of another color, streaking said coat by a brushing operation, jarring said coat to produce a cirrus clouded effect, drying, and fusing said coat to said surface.
