We were
talking about collecting your own lapidary rough in
Part 1 of
this series of articles. By now, you have probably collected a
sizeable pile of rocks that are patiently waiting for you to decide
what to do with them. Or, you may be one of the lucky ones who
inherited your grandfather's or great aunt's rock collection,
composed of some wonderful old-time material that has been mined out
long ago. Either way, the first step is to wash and scrub your
pile of goodies thoroughly before you start sorting them. This will
give you a better idea of patterns and colors of your rocks, helping
you decide what to explore further by sawing, or whether to toss it
on the pile for your garden walls. I like to take a 1/4 inch slice
off the end of my better finds---making a window, so to speak, which
helps make the final sorting easier. You will find that some of
your rocks, while exhibiting beautiful patterns and colors, will be
full of cracks or small voids, making them less desirable for
further lapidary use. The depth of the cracks and voids will help
you make the best use of the stone----perhaps small cabochons or
spheres instead
Now that you have determined which rocks you want to start working up, you will need to decide what their final use will be. You can make cabochons using templates to cut hearts, crosses, ovals, rounds, squares or irregular shapes. You will also need a trim saw, grinding and sanding wheels, and a polishing disc to turn them into wearable and finished stones. If you like freeforms, there are some templates with ready made mountings for this sort of shape available on line. If you like tedious and repetitive work, you can purchase a bead mill to turn your stones into finished beads. However, this also requires cutting endless little cubes, of the same or varying sizes, to be put into your bead mill for grinding and polishing. Then, when they are all pretty and polished, you must carefully drill each and every bead so that they can be strung together to make that stunning necklace or bracelet of self-collected material. Sphere-making is almost the same process as the bead-making, without the drilling of course. It takes a goodly hunk of solid material and quite a lot of cutting to make a decent sized sphere, but the results can be very rewarding.
After the epoxy has cured, it is trimmed away from each stone. The next step is to put each stone on a dop stick, using heated wax made for this purpose. This allows the stones to be ground, sanded and polished with more support than just your fingers. Of course, you can simply hold the rough stone firmly and take it through the steps without a dop stick, but you may find that you have ground your fingernails and sanded your finger tips instead of the stone! Notice the sterling silver bezels on the left side of this photo--these stones are being cut to fit those bezels, which will be finished into earrings, rings, pendants or bracelet stones.
