No, you're not wrong at all! In fact, we once used to live in a rental place where the bathroom walls had been tiled with a hard yellow fossiliferous limestone (kind of like the Belgian Petit Granit, but yellow and with shell inclusions rather than the corals and orthocones of the latter). The effect was quite spectacular! 1 'There's nothing like millions of years of really frustrating trial and error to give a species moral fibre and, in some cases, backbone' -- Terry Pratchett Link to comment Share on other sites More sharing options...

At the time I had only just picked up my interest in paleontology and geology again, or maybe not even... In any case, I remember it looking something like this, though with quite well-defined fossil gastropods and bivalves in it (source): 2 hours ago, IsaacTheFossilMan said: Interesting, a quick google search picked this up: http://wp.greenriverstone.com/wp-content/uploads/2016/05/Bath1.jpg That's truly stunning! And utterly decadent, of course...! Still, similar things are done with the fossils of the Posidonia Shale (Holzmaden-area). I mean, in the end we should not forget that many of these stones are not primarily quarried for their fossil content - which is often just by-catch. And as these rocks are just considered regular building natural, there's no concern over it wearing down or destroying fossils, except for in calculations of lifetime and replacement cycles... 35 minutes ago, FranzBernhard said: How about that these?

Same here in the Cotswolds... Cotswold stone is quarried as building material, and all the homes round here are made of it, but it's world-famously fossiliferous, so you can see shells and other bits all inside the walls! ~ Isaac; www.isaactfm.com "Don't move!

Fossil Fen Posted January 18, 2022 Share Posted January 18, 2022 I know there are a number of different solutions you can dissolve the B72 into, is there any one type that is the best for fossil consolidation? Link to comment Share on other sites More sharing options...

Tough question! I wouldn't really know the answer... Acetone, I believe, is the most commonly used, but I've also heard alcohol should also do the trick. I'm not sure if there's much of a practical difference, since the relevant chemical properties are more or less similar: they both dissolve Paraloid B72, both evaporate quickly and are anhydrous (which is relevant in particular with respect to pyrite), both are slightly toxic but not to the extent to cause any serious concerns, and neither should cause any reaction with the fossil in question. May be @Ptychodus04 has an answer to this one...

Randyw Posted January 19, 2022 Share Posted January 19, 2022 I use acetone to disolve mine into. I use a concentration of roughly 50 to 1 ratio for my consolidating most of the time. (50 parts acetone to 1 part paraloid by weight) Link to comment Share on other sites More sharing options...
Ptychodus04 Posted January 19, 2022 Share Posted January 19, 2022 There’s no one size fits all solution. I use acetone for my solvent but ethanol is also acceptable if you’re ok with a longer set time. I use 50:1 for a general stabilization solution, 25:1 for specimens that are more porous, 10:1 for others with bigger cracks. I regularly use a combination of multiple viscosities. It all depends on the condition of the fossil/matrix. 1 1 Regards, Kris Global Paleo Services, LLC https://globalpaleoservices.com http://instagram.com/globalpaleoservices http://instagram.com/kris.howe Link to comment Share on other sites More sharing options...

It all depends on the condition of the fossil/matrix. I'm going to need a Fossil Forum intervention. I used the B72 for the first time today, with Acetone, at a ratio of about 5% and it is amazing!! I confess I like a bit more of the wet look than most, but on the shells I was working on, it brought out the colour beautifully. I'll try using a 50:1 ratio in the future for stabilization, but I'm going to have to stop myself from putting it on everything!! 3 Link to comment Share on other sites More sharing options...
Ptychodus04 Posted January 19, 2022 Share Posted January 19, 2022 Those bivalves look great. Stabilizing has its place for sure. Sometimes, as with your bivalves, it will enhance the overall appearance, but most importantly, it will harden delicate specimens. Fossil bone is often desperately in need of stabilization in order to remain intact. Conservation grade plastics like Paraloid, Butvar, and Vinac are indefinitely stable and reversible. This is why museums use them. If you want to reduce the sheen imparted to the specimen, you can wipe acetone on the surface to remove the top layer of plastic that is there. 1 Regards, Kris Global Paleo Services, LLC https://globalpaleoservices.com http://instagram.com/globalpaleoservices http://instagram.com/kris.howe Link to comment Share on other sites More sharing options...
