Vaniman Posted April 13, 2018 Share Posted April 13, 2018 Figured I'd share my current project here. I'm currently testing different sandblasting media and their effect on various matrices since this is a somewhat new application for us at Vaniman. The picture is an almost-finished Green River Fish that's roughly 4" x 2" in size. I will be doing a full-scale article regarding the entire process but wanted to share some of the work with you all for fun. I have a lot more pictures so if you're interested- let me know. It's only letting me upload one (?) Please PM me for more info on our products. Link to comment Share on other sites More sharing options...

Tidgy's Dad Posted April 13, 2018 Share Posted April 13, 2018 Nice fishy! Your pictures probably exceed the size limit per post. Either reduce the size of the pictures or refresh the page and post the pics one at a time. You could add another one now for instance. As long as it's not bigger that 3.95 MB, I think it is.

Jeffrey P Posted April 13, 2018 Share Posted April 13, 2018 Awesome looking specimen. I'm curious about the method(s) you used to expose it. Link to comment Share on other sites More sharing options...

Hi @Jeffrey P I will have a full article detailing this whole process but to answer your question, I only needed to use sodium bicarbonate (50-70 um particles) using variable pressure ranging from 40-70psi. The interesting part was that the surrounding matrix which did not touch the fossil was surprisingly soft however once I got to the areas which were resting ontop of the fossil the material seemed to be harder. I'm not sure if this is common as this was my very first prep job with one our sandblasters. Hope this helps! Please PM me for more info on our products.

Vaniman Posted April 13, 2018 Author Share Posted April 13, 2018 Looks like this is a Priscacara serrata from my searching in case anyone, however unlikely, didn't know. Please PM me for more info on our products. Link to comment Share on other sites More sharing options...
goatinformationist Posted April 13, 2018 Share Posted April 13, 2018 V, you are doing just fine. Can't wait to read the whole story. Don't even bother with the car chase or fiery explosion, it will be interesting enough. Link to comment Share on other sites More sharing options...

Sagebrush Steve Posted April 15, 2018 Share Posted April 15, 2018 I will also be looking forward to your full writeup. I’ve been prepping a Knightia eocaena from the Green River, but doing it by hand with needle probes. I have a similar amount of matrix around the bones. I don’t have an air abrasive system but was thinking I might have to invest in one if it can get rid of more matrix. Would like to see what you can do. Here is a link to my post: Link to comment Share on other sites More sharing options...
Bone guy Posted April 15, 2018 Share Posted April 15, 2018 Beautiful fish and good prep Job. I wonder how his head got squished? We may never know. Link to comment Share on other sites More sharing options...
Vaniman Posted April 18, 2018 Author Share Posted April 18, 2018 Nice work @Sagebrush Steve From what I've seen thus far, there seems to be some variable complexity to the matrix and organic remnant explosions which I find fascinating. It seems each little guy has a fate all his own. My fish, for example, lost part of his head, and you can also clearly see the tail "flaking" off which the sandblaster easily revealed during the prep process. I used one of our sandblasters for roughly 6 hours of prep time. I left the upper section with a slight matrix "film" to show the delicate ability of our sandblasting units. My limitation is that I only have the sandblaster and do not have a nice pick tool which I feel would really be nice for super tight areas for even further detail.
