The invention relatesto the edge decoration of plates, dishes and other articles of 2 table earthenware, and more particularly to a process for under the laze edge decoration of such articles, by which a feather edge or ripple edge decoration is a plied.

- 'Themethod, now in genera use in potteries throughout the country, for applying an under the glaze edge decoration to sue 10 articles re uires theservices of, highly skilled. wor ers who have to serve an apprenticeship of three years before they be- 1 come 'sufiiciently expert. in their work to produce a salable article.

118 This ordina method of edge treatment is-accomplishe by a plying a line of muform thiclmessaroun the e ge of the plate, or other articles to be decorated, by means of a camels hair brush dipped mcolor 20 mixed with oil. I

It is then necessary for the plate, or other articles so decorated, to be fired in what is known as a hardening on kiln, in order to drive out the oil and cause the colorto If the color were not sub'ected to this hardening on fire, it woul not be possible to roperly glaze the were by dippin it in t e usual manner, as the glaze wou d not cover the 80 color, and also the color would be so easily removed by contact that it would be en'- tirel too fra ile for practical purposes.

A' ter this ardening on fire, the plate, or other article, is then glazed by dipping, after which it is again placed in a kiln and fired to harden the glaze. Thus it is seen that in the usual method of applying edge decorations to table earthenware, skilled workers are required and two fires of each article are necessary. It is impossible to apply the edge decoration by the usual method without the hardening on fire, as the continuity of the edge line would be broken by contact with the workers thumb or fin ers if the article were dipped before the ardening on fire, and furthermore, as above described, the glaze would not cover the color in the ed e decoration unless the same had been fire Another method of applying edge decorations under theglaze,.which is used to some extent,.is the printing recess in which a copperplate engraving is made of the edge decoration and the same is applied by hand to the article. In this method, as well as the ordinary and usual method above described, it is necessary for the color to be hardened on by a hardenin on fire, before the article may be glazediy dipping.

The object of the present improvement is to provide a novel process by means of which edge decorations may be applied to table earthenware by unsln'lled workers with. onl a single firing of the article, thus material y reducing the cost of decorating the edges of such ware.

The" above, and other objects which will be apparent as-the description continues, may be attained b' applying a ripple edge or feather edge ecoratlon to the ware, using a water color which does not require a hardening on fire before dipping.

This ripple or feather edge decoration does not require the services of a skilled worker and may be easily and quickly applied to the ware by any desired one of several metiods1 bed i 1 m pre erre met 0 ap 'ngt 's edge decoration is by the use of camels hair brush dipped in the water color, the strokes of the brush being made across the edge of the plate ortoward the center thereof, producing an edge decoration of more or less irregular shape. No hardening on fire is required to harden this water color decoration before dippin and it has been found that the contact 0 the workers thumb or fingers with this irregular edge decoration s rayed or otherwise appliedto the edge of t e plate.

In the accompanying drawin Figure 1 is a plan view of a portion oi a pggte to which the new ed decoration has n apthe edge plied as by a b Fig. 2, a similar view showing decoration as applied by a stenc and Fig. 8, a similar view showin the efiect of edge decoration produced y a silk sponge.

Similar numerals refer to similar parts throu bout the drawings.

Alt ou in the drawings the invention is illustra as applied to round plates, it should be understood that this is only for the purpose of illustration and the invention is equally applicable to the edge decoration of square, oblong or other shapes 'of plates or, in fact, any earthenware table artlifiles. th ed h carrying out e process to pr uce t e edge decoration shown in Fig. 1 of the drawings, the edge portion 10 of an unglazed plate or other earthenware table article indicated generally at 11 may have the edge decoration, shown at 12, applied thereto by means of a camels hair brush, using a color combined with water. the strokes of the brush being across the edge of the plate radially toward the center thereof, roducing a more or less irregular decoration, as shown on the drawin This water color used fir the edge decoration does not require a hardening on fire before dipping and is easily covered by the glaze. This permits the unglazed article with the edge thus decorated to be dipped and then fired, completing the decoration of the plate in a single fire as com ared with the two fires necessary under t 0 method now in general use.

If desired, the decoration may be applied. by using a stencil with the ripp e or feather edge design therein, this stencil bein placed over the plate and water color, as a ve referred to, being sprayed thereon, producing an edge decoration such'as illustrated at 13 in Fig. 2. A

As shown in Fig. 3, 'the edge decoration indicated at 14 may be applied by means of a small silk sponge using the water color above referred to. The processes indicated in Figs. 2 and 3 are otherwise carried out in the same manner as above described regarding Fig. 1.

From the above it will be seen that the improved process for ed decoration of earthenware materially re uces the cost of such edge decoration as the decorating may be done by unskilled workers and the hardening on fire necessary under present. practice, is eliminated.

I claim:

1. The under glaze proces of edge decorating table earthenware which consists in 'i applying a ripple or feather edge v color decoration to the edge portlon of a piece of unglazed earthenware, then dipping color decoration to the edge portion ofa piece of unglazed earthenware by means of a silk sponge, then dipping the decorated earthenware before fir ng to glaze the same, and then firing the glazed earthenware.

4. The under laze process of edge decorating table eart enware which consists in applying a ripple or feather edge water color water water lazed earthenware y means of,

decoration to the edge portion of a piece of unglazed earthenware by means of a stencil, then dipping the decorated earthenware before firing, to glaze the same, and then firing the glazed earthenware.

In testimony that I claim the above, I have hereunto subscri my name.

CHARLES 0. SMITH.
