2 Claims.

a variety of contrasting colors and various light- 20 reflecting characteristics.

It is, therefore, an object of the present invention to provide inlaying hard vitreous material with other vitreous material having similar 25 ferent optical characteristics.

sary. v

A further object is to provide an inlaid decorative vitreous structure including 9.,

Further objects will be apparent from the specification and the appended claims.

In the drawing: 55 Figure 1' is a front elevation of one embodiment of this invention and illustrates inlaid vitreous slab constructed with this invention.

Fig. 2 is a detailed sectional view through the a portion of an in accordance embodiment illustrated in Fig. l and taken on a 1 line substantially corresponding to line 2-2 of Fig.1.

Fig. 4 is a perspective view of one of the inlays after being completely finished and ready to be inserted in the vitreous base.

Fig. 5 is a sectional view similar to Fig. 2 but illustrating inlays of slightly different shape in cross section and snugly fitting the surface outlines of the depressions.

Fig. 6 is a perspective view of one of the inlays shown in Fig. 5.

Referring to the drawing in detail, the embodiment illustrated comprises the usual hard vitreous slab 9 having a plurality of

inlays

2, 3, l and 5 embedded in the face thereof. may be of any desired distribution of the inlaid pieces.

drawing is merely illustrative.

The slabs I, particularly when used for building are comparatively large and usually inch thick. In the present embodilike characteristics. strips may be. coated with the ordinary so-called "silver coating" of the usual mirror or with other reflecting coatings of a desired color to provide the desired reflecting decorative eilect. The inlays 3, 4 and 5 in the 2 rected through the openings in the templet, and depressions 8 corresponding to the templet openings, and somewhat deeper than the inlays to be inserted therein, are formed in sand-blast. The cross sectional contour of one of these depressions is indicated by the dotted line in Fig. 3. The sand-blast normally forms slightly concave depressions usually having slightly angular or arcuate side walls as indicated at 9 and with comparatively sharply defined corners adfinished surface. Relatively thin pieces of vitreous material, having the desired physical and optical characteristics, are formed of a size to substantially fit the surface outlines of these depressions.

In Fig. 2 the

inlays

2 and 3 are shown in section after being completely mounted in the depressions with their surfaces flush with the surface of the vitreous base I. In mounting these inlays, a suitable cement of preferably plastic asphalt or similar material It! is first inserted in the depression and the inlay is pressed therein until the surface is exactly flush with the surface of the base. Thesides of the inlays preferably provide a slight clearance between the inlay and the arcuate sides of the depressions 8. This clearance allows the cement ID to flow upwardly around the sides of the inlay to a point closely adjacent the surface. The inlays are, therefore, securely held in place by the cement. The sandblast leaves ,the depression with a slightlyroughened surface which assists the adhesion of the cement thereto.

While any suitable cement may be used, asphalt or pitch or the like, or an asphaltic cement which permanently remains somewhat plastic, is preferable. The inlays may be molded to shapes corresponding with the depressions or they may be cut from suitable pieces of material, as shown in Fig. 4. If desired, the surface of the inlay may accurately fill the surface outlines of the depression and the material may be ground away at H to provide a suitable clearance for the cemen If more than enough cement is supplied in the depressions, the surplus will squeeze through between the edges of the inlay and the base while it is being inserted and the cement will completely fill the space beneath the inlay when the inlays are pressed securely into place with their exposed surfaces flush with the surface of the base.

It will be apparent that this method of inlaying vitreous material with contrasting vitreous inlays provides a structure having peculiarly desirable decorative effects, these effects being prothe base by the duced by the contrasting colors and finishes and reflecting characteristics of the various inlays and mirrored inlays, particupolished surface of the base, which is usually black in color, and with the contrasting colors of the opaque or translucent inlays, provides a decorative slab or sign having a perspective effect not otherwise obtainable in vitreous material having a flat polished surface.

It is impossible to illustrate in a drawing the extraordinarily beautiful effects which may be obtained in the practice of this invention. Howin Fig. 1 an attempt has been made to illustrate the base I as having a highly polished black surface; the border 2 as transparent glass having a reflecting backing of a desired color to produce a mirror effect; and the inlays 3, 4 and 5 as red, blue and green, respectively. Also, as previously stated, the inlays may be transparent, opaque, or translucent in accordance with a preferred design and the contrasting reflecting effects desired. Suitable distribution of contrasting colors and adjacent surfaces having different reflecting characteristics enables the fabrication of a vitreous article in which portions appear to stand out in relief and wherein a depth and perspective effect may be obtained to a degree heretofore considered impossible. Remarkably beautiful changeable effects are constantly produced by either normal or artificial changes in the intensity and angle of light rays striking the surface of the material.

Modifications may be made in the embodiment illustrated and it is desired, therefore, that the inventon be limited only by the prior art and the scope of the appended claims.

- Having thus described the invention, what I claim and desire to secure by Letters Patent is:

1. A decorative article comprising a vitreous base having depressons therein, asphalt in said depressions, and pieces of vitreous material embedded in said asphalt and completely filling the surface outlines of said depressions.

2. A decorative article comprising a vitreous base having a depression in the face thereof deeper than an inlay to be inserted therein, a vitreous inlay in said base having its exposed surface flush with the surface of said base and completely filling the surface outline of said depression, and a layer of cement filling said inlay and extending upwardly around the sides thereof closely adjacent the surface outline.
