I had quite a lot as it turns out. Perhaps 3 1/2 feet?

Wow! Swelled right up!

Here are the real pictures

The Oven setup: note the melted gunky stuff on the "smoking kills" label. The rest are self-explanatory.

Lovely stone and getting him out of there paid off in seeing that it is big 'un.

here's a closeup

Woah, that was certainly quick! LOL
Thanks for showing it off for us, the hone Pron is always appreciated! you are very lucky to have one

Really, the entire process only took 20 minutes. The oven was set on low, and after the pitch began leaking out and bubbling I removed it and wiggled it free. Easy.

I humbly recomend this method for removing stones. I've got a couple more to try it out on.

Congrats to that stone. It looks like one I bid recently on. If it is I am glad that it stayed in the community.
For removing the stones out of boxes. I try first to tap edge of the box the on my palm/wrist edge. If that does not work then either with rubber bottom of my hammer or with a piece of wood tap it on the edge again swapping sides as it comes out.
This method is for me preferable as it leaves the putty cold and more brittle. It is easier afterward to remove remnants of it out of box and stone.
However sometimes it is not enough and it has to go to oven.
Then I put old newspapers on the oven shelf and on top of it two pieces of wood just 1" ish thick (more if you expect the hone to be fatter than that). Distance between these two is just a bit wider than stone lenght. Plce the stone in its base upside down on those two pieces of wood and switch oven on. You can go even higher with temperature. I went up to 150 degrees Celsius. Keep an eye on it. When it drops out of the box switch oven off and remove the wooden base. Carefully wrap the stone in toilet paper or other paper with sucking abilities and return it into the oven for cooling down. In mean time (and if you want to reuse it) try to remove as much of the putty out of the box as the wood will try to suck in the oil melting from the putty.
When the hone is cold then scrape/peel of as much of the putty as you can with using i.e scrapers and brushes. Follow with some degreasing method described on this forum.
Flatten, lap and use. Good luck with using it.

Important bit is warm it up SLOW and let it cool down SLOW as fast. changes in temperature could make it to crack or desintegrate.

I agree with everything you said, and other than use a lower temperature, everything was done as you described. Mine had no putty, and I suspect was only held in with pitch. I tried knocking and rapping, but it never came out. It really took the heat to melt the pitch. The pitch simply bubbled out, and all I had to do was wriggle the rock to release it.

oh... I didn't get it on eBay. I got it from the guy at the place with the stuff.

Haha! Being secretive with your sources there Mark..? I dont blame you..!

Nicely done! I was very surprised at how much stone there was mounted in the box. Its almost twice as thick now that you've got it unstuck.

Are you bringing her to the Razorcon..?
