All About Paraloid B72 - Fossil Preparation Techniques

[@trongod2000]

Wish you were my bar tender. Your idea of "a little bit" would make me a happy camper. LOL

[@EmGems]

Hahaha 😂😂

[@donaldbrizzolara7720]

Em: Great video as usual! Just one suggestion. At some point you might discuss any potential safety issues in handling paraloid. You may have done that in the past but it doesn’t hurt to retell it. There are some issues with breathing vapors and avoiding skin and eye contact. I just thought the public should always take proper precautions when handling chemicals such as these.

[@footrot17]

If you need a yt channel to teach you really basic safety, YOUR Parents FAILED. It's acetone bro lol nail polish remover.

[@gregorybrown8850]

@@footrot17 Unless your parents are chemists, they probably know little nothing about appropriate safety precautions for handling organic solvents. Active hobbyists and professional preparators face vastly more potential exposure than those who use fingernail polish remover. Sharing your cavalier attitude toward safety, which may be fine for you, is irresponsible and dangerous. Do what you wish, but don't make fun of those who are utilizing and advocating proper safety measures. More than one of my colleagues have died young for not doing so.

[@EasterMegs]

Thank you so much for this video! Found some plant fossils recently that are in a very crumbly rock and I'm excited to try this out!

[@cmac1100]

I did wonder about this after having watched several of your videos. Thanks!

[@robsadv]

One thing I would add is the importance of moisture. All specimens should be completely dry, otherwise the coating might get cloudy. Use IR light to dry your specimens.

[@almontepaolilli7531]

Looking forward to more videos on this topic.

[@rosso_d8485]

Great timing on this vid.... Just had some delivered earlier in the week and have never used it before. Going to test it on some beach rocks first, before I go near any fossils.

[@Dan-56]

Looking forward to an in-depth video on the “drill project” that produced the specimen you were working on 😃👍.

[@respectanimals2]

Loving your vids as always , I’m going to give it a go, thanks for sharing the info and keeping us all stoked on the fossil collecting life , peace ✌️ 😎🌴

[@Halite47]

What an informative video. Thank you very much.

[@arasethw]

Does it work to hold together, very old disintegrating Bone ? if not what product is recommended ?

[@DreadEnder]

It’s great stuff!

[@mariuspaleontologie8703]

Very good tutorial! Helped me a lot! Thanks

[@boubakar5168]

Super video em 😊😊

[@rick1785]

Em, excellent information! Easy to follow and nice results. Looking for a local Paraloid source now :) thanks for sharing!

[@nazarnovitsky9868]

Thank you for your Amazing and interesting videos ! 😊👌🏻😁

[@jacobhudson2745]

Thank you for the video I was looking for some help ! How would you do fragile bone ? I don’t want a shiny look for it.

[@gayle4s383]

Thank you; first time user, to be of Paraloid B72

[@nicolorx8336]

Bonjour je suis français luckily there are subtitles 😂, thank you for your videos, they are superb, I have a little question, for bones in a very friable rock, what percentage of paraloid should I put in relation to acetone, thank you for your answer Nico

[@ForgottenFossils]

Great video. I like the idea you had about cleaning the glass when you've done with it. How long do you leave it out to evaporate. I have been throwing out my used ones.

[@EmGems]

Overnight tends to do it for me, as long as they aren't too full!

[@paleocat6354]

I love your channel!!!

[@Drizzt573]

Awesome 👏

[@veterangaming9511]

THANK YOU

[@richardallin7202]

Just the video I've been looking for! Have you ever used b-67?

[@erickyu327]

need any ppe otr special precautions? toxic fume etc.

[@DreadEnder]

I have some in I believe 5% acetone

[@niko73le]

Paraloid makes things pop!

[@nateynate2488]

What a pro you are! Can I use paraloid on bones cleaned from hydrogen peroxide? How does it perform on pores in bone?

[@simonhedger9378]

Really helpful video thanks very much - can the paraloid solution be left in the jar for a few weeks or does it need to be kept in an airtight container?

[@EmGems]

I leave mine for a few months in a jar and it seems to bes fine! But yes if it's airtight and kept out of sunlight it should last! :)

[@guycleveland3897]

You are awesome. I am wondering how thin you can mix this without it not be effective? I do not like fossils that are painted to be too shiny. Is there a more precise measuring formula?

[@aka_rook]

What depth was this ammonite located at and what was the bore start altitude / location?

[@chrisz881]

it's available to use paraloid B72 dissolved in acetone at a 1 to 50 ratio to protect some teeth fossils which had repaired or restored?

[@Shipslaw]

Will that solution penetrate wood (to use in stead of Cactus Juice)?

[@GemPassionpl]

You are EEPIC :) Im dreamming to make things like you :) im also begining work with stones, i hope one day... :) Regards!

[@bondeandeebowl]

Would this method be useful for bones that are a bit chalky? I have some alligator bones that are somewhat brittle that I would like to preserve. Would I need a thicker solution? Thanks!

[@simonhedger9378]

Sorry another comment from me…! Do you use any matting agents (fumed silica etc) to make the solution less glossy? If so do you have a preferred agent and a mix ratio?

[@EmGems]

You can comment as many times as you like! :D I haven't tried any yet, but I'll definitely do a video when I do!

[@dannoakl]

I’ve read that Industrial Methylated Spirits do that. Use 50/50 mix with acetone. But I’ve not tried it myself.

[@michaelripley4528]

Sometimes I wonder the age of your fossils - just for the science freaks like me 🙏🏻 Thanks for sharing and all the kisses 😅😘 Kind regards “the fossil”🤣

[@mateuszjabonski2924]

Great video! What do you think about spray application of paraloid b72 on metal, to make anti-corrosion layer? Have you encountered something like this?

[@EmGems]

It's a great idea but I think the paraloid would clog up the spray bottle very quickly so you would have to trial it and see if it would be possible

[@medas7126]

I was wondering if the same solution would preserve a crystalized fossil? I found a beautiful crystalized ammonite, but I worry that it will fall apart if I don't coat it in anything.

[@gregorybrown8850]

If the crystals are pyrite or other unstable mineral, coating will do little to prevent deterioration because coatings do not cover perfectly and most are somewhat moisture and oxygen permeable. If the specimens are pyrite, the only way to arrest (or at least retard) the chemical reaction that leads to deterioration is to keep the specimen in a stable, low humidity (below 50%) humidity at the very least and, if possible, enclosed in a barrier container with oxygen scavenger. The latter is probably beyond most people's capabilities, but stable low humidity is a must.

[@medas7126]

@@gregorybrown8850 Thank you.

[@royalsquishy7058]

If I used this solution how long does it take to cure

[@ashleyramdath2907]

wow 😀

Ask and ye shall receive!!! ,.. Usually,… well,.. sometimes 🌞 Are you a “Trekkie” as well ?? 🖖

[@Joel-McConnell]

Are there any water based substitues that can be used instead?

[@EmGems]

Hi Joel, I haven't come across any yet - but a very easy alternative is using clear nail varnish, it never needs to be mixed and comes in a handy little pot! This option wouldn't work as an adhseive though, but would add a lovely shine (and it can be reversed if required). Hope this helped!

[@Joel-McConnell]

Thank you! :) Been collecting rocks very seriously for over 30 years and only recently have become interested in fossils. Maybe because I am becoming one! lol! I appreciate the reply..... :)@@EmGems
