INTARSIA

The first step in the creation of this type of work is to find the necessary material. Since one cannot go to a store and find a tube of blue rock, much searching, either in the field or through networking among fellow rockhounds and gem dealers is necessary to secure the materials needed to make a picture. This process can take many years to accomplish. The next step is to slab the rocks into usable slices of the proper thickness. The Italians and Native Americans generally use thin slices. Many other artists use thicker slices, either those that are slabbed for cabochons or a slightly thinner slab used specifically for making commessi. Slabs available on the market are usually of the thicker variety, since most lapidaries make cabochons and not commessi. Some Italians still slab their material by hand with a wire saw. On the other hand, Americans use modern slab saws in order to slab sufficient material of the right thickness for assembly. This process can take thousands of hours over a period of several years to have enough material to produce pictures. The next step is to cut and fit the pieces together. Here the techniques are as varied as the artists themselves. The Native Americans generally use ancient Zuni techniques. The members of the San Francisco Gem & Mineral Society use a modern router assembly for inlaying the stones. The Jewelry & Allied Arts Club of California developed many specialized techniques using a whole range of machinery and handwork. The Castro Valley Club members use a Fab-U-Lap machine for precise fitting, and others developed several unique methods on their own. The one thing that all of these artists have in common is that whatever technique is used, it is extremely labor intensive and the larger pieces can take thousands of hours just to assemble.
