Hi guys, I posted recently in r/bioengineering but they suggested I post here instead.
I'm working on making my own synthetic fossils using a hydraulic press (i.e. a 12-ton bottle jack and steel plates) and a matrix of pulvurized lime and clay.
I've had success with creating convincing sedimentary rocks by filling a small 1 inch brass pipe with this matrix and pressurizing it.
However, I want to include plant tissues in this matrix to create fossils.
The tissues need to be mostly/entirely replaced with minerals, leaving a true fossil within the rock.
My method for this could go two ways. I can try what this guy on youtube has done and simply let natural decomposers remove the organic material, or I could expedite this process by decellularizing the tissues and leaving only the basic structure of the plant behind.
I've had decent success with simply soaking plant leaves in tide pod fluid but they're still green afterwards which tells me I haven't removed everything I could have.
Thus, I have two questions:
- what is the best decellularizing method for an at-home setup? I may also want to move onto animals too so what would be a good process for those?
- what is the best way to introduce minerals to the plant/animal tissue after decellularizing? I imagine I need to dissolve silicates and calcium carbonate and saturate the "fossil" with these while under pressure.
Thank you!
