Ciao a tutti ! I wanted to have some information about the use of chemicals for the preparation of fossils, let me explain better. I'm currently in my second year of PhD in chemistry and I have a wide range of chemicals, bases, polymer acids etc. My question is what could I use for example to clean the limestone matrix compared to the classic diluted acetic acid? is there anything better that maybe I could have in the lab? I had thought of some stronger acid but I'm afraid that using something stronger could be detrimental to the fossil itself... Grazie !

I asked the members here a lot of questions, and read through every thread on building a prep box, some of them many times. Even though I finished the box last year, I finally got off my lazy butt and finished the video. Thank you all for your help! Hopefully this can give some ideas or help the next member looking to build their own.

I think that I posted some pics last year as I worked my way through a prep of a very large Phareaodus fish from the Green River fm near Kemmerer WY. Sadly, its a broken slab and I only have part. I have prepped out to the outer edge but had to stop because that edge is slanted and leaves the fossil layer very thin and fragile. So I came up with an idea. I'll fill in a box of the missing area, finish the prep, and then paint on the missing fish area.. That way I can display it and its still visible for what is real and what it would have been. So, I took a pic and digitally overlaid it o

Hi everyone, hope you're all doing well. I've found this fossil on the pebble beach of Lyme Regis and I just wanted to know your opinion. Do you think is possible to prep this fossil or maybe it will only cause damage? It's 2x2 cm Thank you!

Ive decided to start a crab prep thread instead of doing a post for every single crab I prep. If it works, great. If not, then I will go back to seperate posts for each. I will start with this one that I just started today. This is Pulalius vulgaris from the state of Washington and Eocene in age. This was 'Whacked' open by my youngest son. Turned out to be a purty good whack. This first picture is with the top piece of rock tossed away and the 2 pieces you see on the side are pieces from the bottom of the rock. You can easily see how the crab is not situated correctly in the rock.

Hello everybody. Besides being busy making fossil prep video's, I'm learning a new editing software program that is much much better than the first one I learned. Way easier and much better to handle/play/control audio with this one. Anyways, I made a 5 part crab prepping series and this is Part 3. Part 4 and 5 will be published the next two saturdays. Enjoy Oh, this video is just under 3 minutes so it wont waste too much of your time. https://youtu.be/-GMQEFqw5MQ

I finally found the blaster I have been looking for; a used Comco MB-1002 in decent shape. It also came with a blast box work station, but I dont have a use for it right this moment. I have to order a maintenance kit for some worn parts, but its functional. It goes through media WAY faster than my Vaniman, but it works so nicely. I dont know what size the tank valves are, and may need to order new ones as I suspect they could be too large for my media (and the reason its eating through it so fast). Now that I have my custom blast box, microscope, dust vac, and now this Comco, I ho

This is a chemistry test/quiz that relates to fossil prepping and the follies that ensue. After prepping some silicified Paleozoic coral, I noticed these needle-like salty crystals. They were up to 0.5 cm long. What do they have to do with tofu? What are they? How did they form; use equations or words? How can you prevent their formation? Good luck and have fun.

After rebuilding my prep station to accommodate working with my new microscope, the final part was to upgrade my air delivery with a super-sized desiccant filter. I was tired of changing out my desiccant beads 2 - 3 times a day during heavy use, so I made a DIY filter using a home water filter system. Now instead of using 4 ounces of beads, I have 4 pounds! That should finally give me a decent interval between changes.

Finally able to upload the pics of the finished prep box! Shows the way it opens for loading, the LED light strips with power switch and pig-tail plug for my shopvac so it all comes on together. Also have a small mag lens for preps where I don't need the microscope level of zoom. Now I just have to finish redesigning the air supply. Also, I may have just won the lottery. Waiting to hear from the company for a shipping quote. --- Side note, the purchase price was $50.00! I think a mod edit

I was recently given an Oreodont skull that someone had started but he gave up on it after breaking it into 5 pieces. One of my relatives who knows him was talking about how I’m into fossils and the guy just gives it to him so he gave it to me! So it’s my next project. Even though it’s not in the best shape I’m still excited to get it! I love prepping fossils even though I can only do it on my days off.

Prep lab redesign, new blast box and new microscope!
hadrosauridae posted a topic in Fossil Preparation
I decided that I had put it off for long enough, so recently I torn apart my work and rebuilt it at a proper working height. I also built a test blast box out of cardboard in order to better evaluate the usage with a boom-arm microscope. And lastly, my new Swift S7 microscope arrived! -
I am in the process of designing my new prepping blast box, and I decided to make a cardboard mockup. After the advise members gave in my last thread, I tore apart my work bench, and rebuilt it lower to accommodate a box. Since I am just about to pull the trigger on a boom microscope, I wanted to wait until I actually have it to make sure the working height, depth of field, etc are all going to work with the box before actually making it. I used @Malcolmt box design with a slight mod. The box is 24x20. I thought about making it larger, but I decided that was probably

OK, I missed the Fossil Friday post by a day. The cold weather lately has kept me indoors and away from fossil exploration, so here is a partial prep of a partial ammonite from the Lake Texhoma Duck creek fm. Prepping something no true separation of "fossil" and matrix is quite challenging, especially considering how well they can, at times, weather out and become separated naturally. The matrix seems to be getting harder to separate as I move toward smaller sections. I can make out that this does have the inner whorls , so I dont want to blow them out. This has really slowed me down on t

Hello everyone, I have a couple ammonites that are above my skill level to prep. Anyone in the Dallas, TX area good at Prepping? George

OK prep gurus, I come with a question. What is (or is there) a preferred height for the table top a blast-box sits on? My HF sandblasting cabinet has served me well for my micro abrasion preps, but the time has come that I need a single work station I can both scribe and blast in. I'm going to have to tear down my current work bench anyway to do this, and I think it is a little too high. So do you have a preference for the height?

As promised, here is episode 1 of my goofy fossil prepping video's. A super cool and fun way of showing viewers a very comedic way of prepping out a fossil crab. I really did prep out this fossil crab. I'm such a goofy guy and with the help of my son Cory, this is what we came up with. This is episode 1 of more to come.

OK, I have a question for the learned members of the forum. I finally got some dolomite powder for my blaster (absolutely love it so far!!) and put in a few hours of using it last night, and it raised this question: Do I need to bake my dolomite to dry it before using (or storing)? I have read that dolomite is hydroscopic, and I have noticed this brand new powder has a strong tendency to "bridge" in my media canister. I also had several instances where it seems like a clump of it would exploded on the fossil being prepped. I'm not getting blocked, its not plugging the line or th

Crab Prep Questions: what to do with a multi-crab concretion??
Fossil Fen posted a topic in Fossil Preparation
Hello All, (WARNING: FIRST TIME CRAB PREP AHEAD) A friend of mine came across a small concretion (2.5") on a marketplace website and picked it up for me. It was already cracked open right across the equator, and exposed a small crab. (I'm assuming from Washington State but anyone that can weigh-in on the species is appreciated.) As per the pictures, the Crab itself has the body and the claw separated into different halves of the split. Reading up on the forum I decided to glue the concretion back together and air scribe my way back down to the Crab in the hopes of conso -
I recently started a new YouTube channel exclusively for hosting my fossil hunting and prepping content. A lot of people who are new to fossil prep are curious about how other people set up their work areas and what tools to use, so I made my first video to discuss at this topic.

I recently found a lot of great teeth in soft Eagle Ford formation slabs, and I'm working to prep a few to expose them better. This is my first prep project ever. The slabs are quite soft, and break apart easily if I'm not careful. What can I do as a preventative measure to avoid breakage of the matrix, and if matrix pieces have broken apart, is there a glue that I should use to get them back together in one piece again? Also, one of the slabs has a mosasaur tooth in it, and near the tip is a tiny crack that I'm worried may completely fail, breaking off the tip. I would like to fin

Its fossil Friday! Share your latest fossil picts.
hadrosauridae posted a topic in General Fossil Discussion
Its fossil Friday, so share a pic of your latest fossil acquisition, or prep. This is my latest prep project, a large Mioplosus from the Green River fm of Wyoming. Its not 100% finished but getting very close. Sadly it had already lost 1/2 to 2/3 of the tail before I found it, it has some damage to the rear dorsal fin, and the original break/exposure was through the head so it will take extra work to remove the glue used for an improvised field repair. I did learn a good lesson and will be bring proper consolidates and glues when I go fishing this year.
