The surface of a stone can be prepared or worked to a number of different finishes. Below are examples and descriptions of some of the most common surface finishes used on Stone Age Creations products:
- POLISHED - A polished stone finish is the most labor intensive and generally the most expensive. The process of polishing a stone usually includes 7 steps of polishing a stone with progressively finer grit polishing pads. Even before the polishing process begins a stone is often worked with saws, chisels, and grinders. As you can imagine, to go over the same surface of a stone sometimes more than 10 times to achieve a polished finish takes a lot of time and patience. Granite, basalt, and jade take a polish well and will have a finish that is reflective and smooth as glass. Stones like sandstone and limestone will become very smooth, but usually not 'polished.'
- FLAME FINISH - A flame finish is applied using a torch at temperatures of nearly 3,500 degrees. By super-heating the surface of the stone it will quickly expand and pieces will flake off. This leaves a surface finish that is textured to resemble the natural weathering process. A flame finish can only be applied to certain stones. Most types of granite or basalt are fairly easily to flame finish while most sandstone and limestone can't be flame finished.
- NATURAL - A natural finish means just what is says. . . The surface is as Mother Nature created it over thousands of years. The stones we use with a natural finish are collected or gathered as opposed to quarried because the quarried stones we use are typically sawn or blasted from a larger rock formation. We offer a selection of different sandstones, granites, and basalt with a natural finish.
- CHISELED - A chiseled finish is created, as the name implies, by breaking a stone with a hammer and chisel. Depending on the type of chisel used and skill level of the person using it, this can provide a very rough surface or a slightly irregular finish. A chiseled finish can be applied to any stone.
- BUSH-HAMMER - A Bush-Hammer is a specialized stone-working hammer with a head that resembles a meat tenderizing hammer. Because the head of the hammer is usually small (about 1-2 inches square) it takes a long time to apply this finish to a large surface area. The pointy ends of the hammer leave the surface of the stone fairly smooth with small indentations. A bush hammered finish can be applied to nearly all stones.
- GROUND - A ground finish is achieved by going over the surface of a stone with a diamond impregnated grinding wheel. A ground finish is the last step in smoothing a stone surface before beginning the polishing steps. A ground finish can be applied to nearly all stones.
