Molding & Casting A 500 MILLION YEAR OLD FOSSIL | Full Series
Вставка
- Опубліковано 6 сер 2024
- Molding and casting an ammonite fossil which is around 500 million years old. There are actually two annomite fossils embedded in the original rock formation - one small ammonite and a larger one. In this series of videos we make a latex mold of the original fossil, build a fibreglass mother mold and cast a replica of the fossil using concrete and plaster of Paris.
Part One 00:00 - Making The Latex Mold.
Making a latex mold from a 500 million year old ammonite fossil. In this video a mold is made using layers of latex. The fossil mold in this video also needs a seam incorporated into the mold for ease of demolding casts for when the mold is completed.
Part Two 11:16 - Building The Fibreglass Mother Mold.
NB: Best to put wax on first followed by PVA application when applying the release agent process.
Following on from the video on latex molding an ammonite fossil, we make a seven piece mother mold to house the latex mold. This video is a short and brief video showing the process and more in depth videos about molding can be found on the channel.
There are many ways to make molds and this video is showing how we make molds here at present, which is our preferred way - it works for us and what works for one person may not work for another.
The model in this video is a 500 million year old ammonite fossil which came out of the mold in one piece. The mold which has been made from the ammonite fossil is now ready to create replica fossils with concrete or any other appropriate material which is compatible with the latex mold.
Part Three 14:55 - Casting The Fossil.
The final part in the series of molding & casting an ammonite fossil. In this video, we finally get around to casting the fossil in concrete and we also make a cast with plaster of Paris.
The video footage is taken from two existing videos on the channel which feature concrete and plaster of Paris casting. There are also two other parts to go with this fossil casting video which are making the latex mold and making the mother mold with fibreglass.

Thanks
Thank you Levent! :)
Awesome work buddy. I’ve been carving Moai heads from breeze blocks. Now I have a way of repeating them in a more durable material. Do you use a seem on your Moai latex mould? If so, just down one side or both. All new to me and very interesting. I saw your link for your fibre glass. Do you have a list of materials I’d need and any decent supplier for these. Keep up the good work, I might have just found a new hobby.
I didn't make a seam for the head I have here and made latex mold in one piece, unlike the fossil mold in this video which obviously has a seam around the back. There's some videos showing the head latex mold on some of the videos on the channel.
The sweet smell of resion ☠️
Brutal! :/
@@dramamask yes it is but man does it bring back memories I worked in that stuff for 6 years
@@MONSTERMISFITS I hope you wore your mask in those 6 years, or was it the fumes which turned you to the dark side? Hahaha!! :D
How long do you let each layer dry before applying the next?
Here's a video especially for you: FAQ #5 Latex Layers & Allowing To Dry When Mold Making: ua-cam.com/video/Scd6wGMJQmE/v-deo.html
Hi do u take any molding class
Do you mean, do I run classes? If so, not at the moment, but I would if there were enough people who would be interested. I'm guessing you mean online classes also. :)
What fibres are you using? Thanks
This is the fibreglass matting I use for making the fibreglass mother mold along with the resin of course: 300gm Fibreglass Chopped Strand Mat: www.mbfg.co.uk/300gm_csm.html
You added a fibre to the latex to make it thicker, sorry I should of been more specific.
@@MrTeazer10 I think that is probably polyfibres or the nylon wool which you might be referring to.
