I HATE when I get a rock marked with that black indelible ink. HATE HATE HATE it!
My best removal is acetone and then WD 40 (switching between removal attempts) and the green scrubbie side of a sponge. PITA to remove indelible ink and even then it may not come off 100%
Went to Google for answers and have tried everything. Vinegar, nail polish remover, gas, rubbing alcohol, - many others.
Have not found the correct answer yet.

Instead of grinding to the line, why not just remove it? That's the problem, I can't remove the sharpie line. Well, adjust the line next time so it’s in the removal area. When I mark the edge of a cab preform, I usually grind the bevel down just to the line, but quite often I’ll grind the bevel down more—till the line’s gone—if I want a thinner edge. No biggie.

I bought a paint pen today and tried it on a Petoskey stone, which is soft and more porous than other rocks. I let it dry for an hour and then poured acetone on it. The paint ran, but I could not scrub it completely off. Soaking it in acetone worked though, so it's a decent solution. The problem is that it will be difficult to soak larger rocks like the ones I'm doing.

Would fingernail polish work? That little brush to put it on and supposedly it can be removed with acetone or whatever the girls use.

I'll see how this goes first. That little brush on the fingernail polish seems like it would be difficult and time consuming to use.

Mark your line with dots (polish dabs), you don't need the actual entire line do you?

On the rock you posted a pic of, I'm betting a 16 penny nail sharpened a bit would scribe a line on the stone. If needed, it's pretty easy to heat treat and harden said nail for scratching harder stones. Be easier to cut to, or remove the scribe line that the thick width of the Sharpie line. The Aluminum scribe mentioned earlier might work well also as it would be thin enough to cut to and remove without having to erase a line of ink, pencil, paint or other mediums.

I marked the cutting lines with fingernail polish. Then used the polish remover when everything was cut. I was not marking porous rocks.

I use a pencil. I generally use templates. I mark the shape on the face, trim and rough grind outside the line. I position the template on the back away from any chips or problems on the back and redraw. When the pencil mark disappears, I use the template and redraw. After cutting the shape to 280, I draw the girdle line and mark a center line on the top. The wheels remove all the pencil marks.

After cutting the shape to 280, I draw the girdle line and mark a center line on the top. The wheels remove all the pencil marks. With my project, part of the rock is going to remain natural, so the mark never gets ground off. I don't have a problem like this when making cabs, only when doing my current project or making bowls. In these projects, I can and do grind off the line, but many times, I have created the surface I want before I get to the line. Then I have to continue to do a lot of grinding just to remove the line. I just got finished spending about an extra hour removing the second line on my current project. After buying a paint pen, testing it on a different rock where I was able to remove it, I used it on my project rock. Of course, then I couldn't remove it. I tried acetone, paint thinner, and a product called "Oops!" that is supposed to remove spilled paint. None of them worked this time, even when the rock soaked in them for hours. I might try the fingernail polish idea next time. Tomorrow, when the glue dries, I'll post pictures of the project I've been working on.

"many times, I have created the surface I want before I get to the line. Then I have to continue to do a lot of grinding just to remove the line" This makes total sense now. Your original line may just be a reference line that is used but if your happy with the way it looks and still 1/8" from the line why continue to waste time and diamond pads. I wonder if something like pin stripping tape (or some other tape) could be used and then peeled off when done? Would not have to be a continuous line either like captbob said earlier. Chuck

Chuck Maybe I have been too quick to dismiss the idea of tape. I should try it. I just think with the gobs of water pouring past it, it would fall off.

Rob - forgive my late entrance to the party - seeing your example rock with parts of the black line on it - what is the harm of going around the corner and sanding the line off with some rough grit sand paper? Would not change the appearance too drastically would it?
Just my two cents - I'm sure you are waay past trying the most obvious thing.

I see fossilman used a gold Sharpie on his 50 performs. Looks like a good idea.

The rock is a completely different color on the inside, so it would be very noticeable.

My mistake, I thought you something about how to removie a mark. There are lots of options. Some marks I'm not sure how to remove. I like a grease pencil Using denatured alcohol to remove it and a tooth brush to get in the Maybe even fingernail polish. Crevices. You would almost have to try all the suggestions to see .
What workS for you. Good luck

A spray can of Toolmakers ink remover should blast it right off !
Check tool makers supplies on E-Bay or locally if you have such a store nearby.
I have used this item to remove Magic Marker from just about everything you could think of, including skin. When using on hands, you might use a well dampened piece of tissue because it is possible to frost bite / freeze, the area being sprayed.
You needn't ask me how I know about THAT one !
