Best resource on consolidants and adhesives for in the field and in the lab?
NickG posted a topic in Fossil Preparation
Hi all, I'm looking for what members would consider an accessible resource on adhesives and consolidants, their preparation and their use in the field and the lab. We primarily collect Paleozoic invertebrate fossils, but also some vertebrate fragments here and there. I'd be curious what people's go-to resources are... particular book titles, webpages, journal articles, etc. I'm looking ultimately to be able to reliably figure out what is needed to ensure our finds are stabilized in the field. We are finding more and more vertebrate fragments and I want to be certain they're kept in good order.- 20 replies

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 -
Hello everyone! I managed to bring home this crazy guy, the problem is that it was so big it broke in pieces when extracting it. I've been using "Loctite Super Glue 3" (ethyl cyanoacrylate) for repairing my fossils until now and it worked pretty well. However, this one might be too heavy I'm afraid it wont be enough to keep the pieces together and it can be dangerous (since the whole fossil probably weights over 70 lbs). There are also some cracks I would like to fill, I heard a technique where you ground some matrix rock to dust and then use that powder to make a glue that has the exact same colour of the fossil, anyone knows about it?. To summarise: what is the best adhesive for heavy rocks? and, is there a way to fill the cracks so it won't look like it's broken? Thank you very much for your help. Here goes the picture of the fossil: Best regards,

Found a paper today using Paraloid B-72. It’s a very useful read for any that prep

I am wanting to remove this shark tooth for photography purposes, but it is attached to the display case via some putty-like adhesive. I haven't tried poking at it in fear of damaging the tooth (which is quite brittle), but it does appear to be somewhat hardened, although I may be wrong. Does anyone know how to best remove putties using household materials with minimal damage to the fossil? Any help is appreciated.
