Prepping a double block


Ludwigia

Recommended Posts

My customer brought me another challenging assignment the other day. It's a combination of 2 different ammonite species in one block, something quite rare for the ovale zone in which it was found. Here's what I started with.

There was a lot of matrix to be removed, so off we went. Here's what it looked like after a couple of hours with the scribes. Now you can roughly see the positions of the two ammonites.

I never cease to be amazed at how abrading can reveal the beauty of fossils. Now the Hyperlioceras can be clearly seen on the left.

There was still a bit of shell clinging to the venter at 6 o'clock, but I managed to scribe it off with minimal damage which I'll conceal later with a bit of epoxy putty.

I then returned to the scribe and trimmed off most of the matrix from the Sonninia. The oyster which is sticking to it was also removed after I took the photo.

The last thing I did today was to abrade the Sonninia. Sometime tomorrow I'll get down to trimming the matrix to give the block an aesthetic shape, smoothing it down and finalizing things. I promise to post the end result when done. By the way, the Hyperlioceras has a diameter of 18cm. and the Sonninia one of 11.

Looks fantastic now. :wub:

Thanks guys. I just love it too. It's pieces like this that cause a bit of envy to well up in me, but at least I can admire it for a while before it returns to its proper home.

Involute and evolute shells facing each other - nice display piece indeed

Yup. It's very pleasing to the eye. It was already there. I just helped it along somewhat.

:look::notworthy: (that about covers it)

Accomplishing the impossible means only that the boss will add it to your regular duties.

Thanks very much gentlemen, but it's the ammonites themselves who are the real stars of the show. It's not all that often that they present themselves in such an aesthetic way. All I had to do in the end was to round it off.

And “David” was already in the marble and all Michelangelo did was uncover him. :P

The colour and pattern looks great. I think your customer is going to be pretty impressed. 

He already is. I sent him a photo and it was love at first sight.
