Techniques for CollectorsEngraving Stone
15th Oct 2010 07:52 UTCBrian Stanford
I joined Mindat in July, 1st time posting.
I'm interested in learning to engrave stone. Word engraving on smaller stone.
I'd appreciate any info or guidance relative to methods, best tools, equipment and stone, links or other information sources.
Thank You:
Brian

Much depends on the hardness of the material you intend to carve / engrave.
I would suggest that any Dremel hand held drill would suffice - you could use dental bits for softer stone and diamond bits for harder material.
Most major hardware stores or lapidary supply house would cater for this.
Cheers

I do have a Dremel, but have had trouble locating any suitable letter templates and find it hard to get a start without running all over the stone, if that makes any sense. No doubt, I need some type of scribe or other tool to mark the stone deep enough to have something to follow???
Thanks Again
Take care:

I forgot to ask what model your Foredom tool is? Did it come with a water drip or is it something you rigged on your own?
Thanks.

In terms of good, better, best, I'd appreciate any experiences anyone has had, or recommendations relative to rotary tools, air gravers, sand blasting, lasers or other stone engraving methods.
Also, if it's allowed to mention company names, does anyone have any tool supplier preferences or is eBay the way most folks go?
Thank You.

What stone/rock are you trying to engrave?

Mostly various pieces of petrified wood that I've ground flat on one side. Also have some agate slabs that I've bought here and there that I'd like to try something on. Perhaps I'm starting out with stone that is too hard ???
Thanks:

Thanks for your reply. Is the diamond extender lubricant you mentioned available at most stores that handle diamond bits or do you go to a specialty store?

Cutting letters into stone by hand is a slow process
You could try outlining the letters first - aluminium pencil - using a letter guide (same as used by architects and the like) then using a small circular diamond saw - carefully cut out the outline. You may need different size saws. Then use either a router type attachment to carve out the inner parts of the letters or use diamond tipped ball or square drill bits.
You could also use letraset as a means of setting out the letters. They will of course be destroyed once you start cutting
A router type attachment - with the drill fixed in a vertical mount will get a better result than by hand. But be warned, this is a slow process. You may need a good deal of diamond slurry to assst. If your material is flat like a slab - ensure that you place on a flat surface. If your material is rough on the other side then you need to ensure that it is flat by placing on a suitable base first. For this you could try a piece of thick packing foam - not affected by water or lubricant but is easy to cut out to mould to the back of your rock. Or simply place on wax as if you were cutting a cabochon and then affix the waxed side to a flat surface.
Good luck
Cheers

I have a tough question which has seemed to be difficult to answer.
I am looking for a rock type that could be carved into WITHOUT using a dremel. So here's the concept, i'd like to be able to carve into a rock just using a small chisel and the pressure or force from my hand. I do a lot of hiking and think this would be a great way to relax, while creating something unique. I remember in class learning about the different types of mineral rocks that could be scratched by a coin or nail (Mohs hardness scale).
If anyone could please suggest the best type of stone/rock that mite work best to create a nice carving by hand I would really appreciate it. Suggesting a chisel would be greatly appreciated as well.
Enjoy the Holidays.

The old practice of lithography, "litho" latin for stone, was actually not a matter of engraving or etching as with metal plate intaglio printing (most world currencies are printed with the intaglio method). The use of stone lithography was a planographic technique in which the artist draws directly on a flat stone, usually with a greasy crayon. The stone is dampened with water, then inked. The ink clings to the greasy crayon marks, but not to the dampened areas. When a piece of paper is pressed against the stone, the ink on the greasy parts is transferred to it. . example:

No engraving stone was ever widely used as a printing plate.

i have a large quartz piece and i'm trying to figure out what would cause what resembles pencil marks in the grooves on the carving. i was told the carving was turned on a lathe, and in some of the grooves there is what appears to be graphite pencil. It doesn't come off despite using eraser, alcohol pads, nail polish remover, or comet cleanser. soap and water didn't remove it either. i was thinking a scribe pencil was used, but that comes off, right? need carver's experience!
thanks!
