BUTVAR B-72 - Is it the same as PARALOID B-72 & BUTVAR B-76?
kenoakee posted a topic in Fossil Preparation
Its been a minute since I've posted About 20 years ago while doing research online for fossil preservation I read somewhere that curators used "B-72" as adhesive and consolidate. so I did some digging and found a supplier that offered up free samples. I ordered some and after it arrived we were moving and it was packed away. the next couple of places I lived didn't afford me the space to do my hobbies and prep my fossils. Much time has passed and I am now able to haul out some of those fossils and work on them. I dug out the "B-72" I had ordered years before and started to look up info on how to properly mix my "B-72". Low and behold I didn't realize that there are other products that use the same handle "B-72". I now see its "Paraloid B-72" or "Butvar B-76" that are most commonly used for this purpose. So what's the difference?, and can this "Butvar B-72" be used? Is there or could there be any negative or undesirable effects from this stuff? will it ruin my fossils? If it can be used, does one dilute it the same as the other products? what W/V % should be mixed for consolidating vs using as an adhesive? Thanks for any input

I wish this was a post to celebrate an incredible accomplishment but instead I am extremely scared that through my potential carelessness, the likely greatest find of my life may be forever changed. I just a few days ago on 6/6 found this stingray fossil at American Fossil Quarry in Wyoming just and was able to keep it because it was at that location. I have been on a road trip and have been storing it in a plastic tote bin with bubble wrap and then fish fossils underneath wrapped in paper towel. I took the lid off for a prolonged period to air out the bin and I think this was a grave mistake and let in humidity. The paper towel was all heavily damp and many of the fish fossils had very obvious signs of mold/mildew growth and discoloration. And now I fear the stingray may show some as well. I desperately need advice on repair and preservation asap. I really need help trying to fix this mess as I’m still on the road for another week. It may not be super obvious in the images but it is the areas that appear a grayish color in contrast to the orangeish brown. The last image is the closest picture I took on the day it was found to show any potential change. This was a lifetime find and I will be crushed if I’ve caused irreparable damage. Please help. Any advice in repair and preservation is greatly appreciated. And I’m sorry to all those that see this and are disappointed in the poor handling of this rare piece, I’m more than disappointed in myself if things are what they seem. And if by a miracle the stingray is perfectly fine then any advice on the fish fossils would be great.

I’ve got multiple pieces of wood, some with original bark, as peat with remenants of stuff in, that is all around 4,500-6,000 years old from an ancient forest, but now that it’s come out of the sea will it just rot like normal? What would be the best way to preserve it?

Hi im and amateur collector and I'm not sure if the was the right section to post this under. I purchased this tusk a couple years ago. The seller said he's had it since the 1970s. Because of the large crack from top to bottom and the inside is quite powdery. Is there and thing I can do to preserve it? Its about 6.5 feet along the curve and 120lb so I get worried when I move it. Also I see that great patina on some tusks is that something that is added 5o make it shine or does it comes out of the ground like that? Any help would be appreciated!

So how do u preserve fossils like shale/limestone and teeth? I heard something about paraloid? Where do i buy it? And i have washed some fossils with tap water when i started fossil hunting. And some say they can get discolored with sunlight How do i know that? I got a old trilo that now have alot of dots of matrix they were not dried in sunlight but the rooms light was turned on i used normal hand soap.

Hi, i collect fossils and other object such as Ancient artifacts, minerals, etc. My question is about preservation. I have a couple closets where i keep all my specimen in a temperature and humidity controlled envitoment (45-55 %), with no light. The closet is Made of cheap wood (bought from ikea) and, at the moment, my specimen just sit on the wood. I want my pieces to stay on a appropriate material, without the potential to affect the side it is touching in anyway. Do you think plexiglass would be better than wood? I know that some types of Plastic, often used in coin albums, can damage the coins, so i'm not sure Plastic materials are good to go. Cardboard is another option but it can contain humidity. Do you have any tip? P.s. I don't want to use vinavil or any other chemical on my fossils. Thank you everyone

How to polish ammolite and make it look shiny and multicolored
RiseOfTheExtinct posted a topic in Questions & Answers
I've posted some pictures of the ammonite I bought and want to polish. If you look at the third picture, (ammonite 2.jpg), you will see that on the ammonite some rainbow color resides. I want to make the whole ammonite that color. Is there any way to polish it to make the rainbow show more? Correct me if I'm wrong, but that rainbow color is fossilized mother of pearl aka Ammolite. Does anyone know the following? If you could answer, that'd be a big help. Thank you for your future words! Any suggestions welcome. You'll never know what will work. The best way to clean and polish the ammonite to make the ammolite show and without breaking the fossil. A way to preserve the color when and if I polish it. Thank you so much, everyone, for your future ideas!

How do you preserve and take care of dinosaur egg fossils
RamenHero posted a topic in Fossil Preparation
Just would to learn more from collectors, how do you preserve/take care of dinosaur egg fossils to prevent deterioration? -
I found this beautiful whale vertebra this weekend. It fell out of the cliff face just a few days ago and tumbled into the Potomac River (brackish?) just far enough for the waves at the tide line to gently lapped it clean. Gotta love it! It is currently soaking in clean water to get the salt and anything else out as much as I can, but I've never done anything this big before. I'm used to stabilizing little stuff and blocks of matrix that really just need a thick, hard outer shell. The little bones air dry quickly enough that I don't have to worry about moisture at the center, but this thing is 4 1/2 inches in diameter! I have both Paleobond and Paraloid on hand. Anyone have any practice at this?

I have been finding fossil wood from cretaceous mud deposits that is still soft. However, when it dries it usually crumbles to bits. Sometimes when it breaks open it is black and glassy-looking inside. Some has pyrite crystals growing on it. What would be a good way to preserve it? Keep it in a jar of water? Paraloid? ????

I was wondering how fossils were preserved and a really cool thread on this site explained using plastic (butvar and others) to do so. It got me wondering, what about before plastic? How did early paleontologists protect fossils? Any links to sources you have would be amazing so I can read more about it. Thanks!

I have dug a number of bivalves and gastropods out of a very friable, crumbly matrix. Anyone have any experience how I can preserve some of the matrix and also make the specimens look good?

I was hunting the peace river a few days ago and found an osteoderm. I was overjoyed to be able to add it to my collection. I have wanted one since I started collecting! When I pulled it it was in great condition. I left it in a zip lock baggie so it had some moisture on the way home. I took it out and let it dry on my desk away from direct sunlight. i was picking some debris from the holes and noticed a very tiny hairline crack. Today it has grown much larger and seems to continue to widen. I don't know what to do as I am a nube. What can I do to save my osteoderm? What did I do wrong? What should I have done? What should I do in the future with specimens like this? (Sub dermal wet bone) Please help.
