Inlaying
5. The process of applying wire, etc., to an incision on metal either by burnishing or fusing the metal into the cavities. Rendering—tint the darker metal or, if possible, render in color. Illustration, [Figure 348].
Stone Cutting
6. An enrichment of the surface by the addition of semi-precious or precious stones. Other enrichment is generally subordinated to the stone which then becomes the point of concentration. All enrichment should lead toward the stone. Small stones may, however, be used to accentuate other points of concentration in surface enrichment. Rendering—shade the lower and right-side of the stone to suggest relief. Pierced subordinate enrichment should be shaded in solid black. A concentric line should be drawn outside of the contour of the stone to designate the thin holding band, or bezel, enclosing the stone on all sides. Illustration, [Figure 351].
Rule 10d. Surface enrichment should at some point parallel the contours of both primary mass and point of concentration, especially whenever the latter is a stone or enamel.
Rule 10e. In the presence of either stone or enamel as a point of concentration, surface enrichment should be regarded as an unobtrusive setting, or background.
Rule 10f. Stone or enamel used as a point of concentration should form contrast with the metal, either in color, brilliancy, or value, or all three combined.
Building
7. The process of applying leaves, wire, grains, and other forms of surface enrichment to the plane of the metal. These may afterwards be carved or chased. Rendering—shade the lower and right-hand lines; slightly tint the lower planes of the metal. Illustration, [Figure 354].
