Looks great! Do you have a before photo? And, if you are going to polish, an after photo? I haven't tried this before.

I am guessing that soaking in vinegar had some sort of preliminary cleaning purpose?

I'm guessing white...but thought I better ask. I have white vinegar...but would have to steal my wife's apple cider from the pantry if that's what's needed! LOL |

When I read this earlier, I was wondering if I used wine vinegar, if it would dye the rock. lol
After all this discussion, I am going to have to take a couple Petoskey stones and soak half of each in the vinegar and then polish them and see if it makes any difference in the final polish.

I do this with diluted hydrochloric acid (muriatic acid, "pool acid") to ether release fossils from the limestone or to put the fossils in more relief.

I just wing it. The reason I dilute it is to control the reaction. If I put the acid on straight it creates a very strong reaction that only last a few seconds before the acid is used up. By diluting the acid, which you do not need much, the reaction is more controlled and I can check my fossils or rocks I clean this way until I get the result I am after. Then I just rinse them off. One thing I found is that the reaction goes on the acid water and the formed calcium chloride solution having different densities do separate. And so, the reaction will stop on the rocks that are out of the acid solution, but the acid is still there. To solve the problem, I stir the solution frequently so that the acid solution is maintained evenly throughout the solution. To test is acid is left or if more needs to be added, I dip a piece of limestone o caliche in the solution to see if it fizzes. I tend to use the same solution for a while and just keep adding acid since tap water has a lot of minerals that will use up some of the acid. By using the same solution and adding more acid, the minerals that were preset in the tap water have already reacted with the acid and therefore does not affect the new acid.    |

Releasing the fossil means separating it completely from the matrix. An example is the one sponge I posted. Relief is where you remove some of the matrix so the fossils stick out more. I generally do with fossil clusters such as crinoid clusters so that more of the fossils are showing, but still part of the cluster. |
