Re: Stabilizing Petrified Wood?

You could try setting it in cement, just mix up cement the normal way then pour it into any suitable container, a cardboard carton or plastic bottle even a plastic bucket will do, then push your stone into the cement until its covered, bounce your container on the ground a couple of times to make sure air bubbles are removed from the cement then set aside to cure for about at least 12 hours then slab it. Timing is fairly critical here, you want to slab it when the cement is hard enough to hold everything in place but still soft enough to allow you to break it away from your slabs, if you leave it too long you may need to soak your slabs in acid for a few weeks or just trim and cut and polish as normal and discard the offcuts with cement still on. Hydrochloric acid is readily available here (Australia) for cleaning cement off new brickwork.
