How do you preserve bark on rustic wood projects.

We are building a fireplace mantle of oak milled from one of our trees 7 years ago.  We would like to leave the bark on the out facing side of our project.  Will epoxy suffice?  we bought a "pourable" type of coating like we have seen on some bar tops.  Will the bark fall off after a number of years?  It hasn't in 7 years in an unheated, somewhat damp barn.  Any help is appreciated.  Thank you!

You might consider just tapping small pins into it, aim into the deepest cracks, drive them just under the surface of the bark with e.g. a small screwdriver - you'd hardly notice them.
The heat-cycling would probably cause the bark to fall off without any fixatives.
