Be sure to sand the slabs smooth and wipe away the sawdust. Apply the varnish with a quality brush following the directions on the container. You may need a couple of coats, with light sanding in between.
If they're fresh they need to dry out for at least six months to a year. If they are dried out them use shellac to seal them or a two part epoxy. Varnish or poly will crack, peel, and flake off.
I would suggest a clear 2-part epoxy. I agree with William that you need to ensure the slabs have dried well before finishing them in either shellac or the epoxy.
Wood slices may be preserved by naturally drying wood outdoors. The wooden slab should be placed in an area in your yard where it is away from direct sunlight and rain. It should not be placed on the ground and air should be allowed to move around the slab to improve preservation. here are countless ways to finish your wood pieces. A few favorites include: staining, painting, varnishing, and live edge wood. When you choose to use a stain or paint, there are a lot of different color options to choose from. You may want to take a scrap wood piece and experiment to make sure you like the color.
Make sure they are dried first, no longer green, then you can paint a varnish onto them with a brush. I would go with a poly finish rather than varnish for my personal preference.
Hello they could split if not completely dried as mentioned above be sure not to rush the process, as I have had a hard time to discreetly fill these cracks on my acquired slices
Hi Pauline, there are so many different options on the market. You can use a waxy wood stain to protect and seal them or you can use a clear polyurethane varnish that you'll find at most craft and hobby stores. If you'll be using the oak tree slices for food, use Shellac or Tung Oil. Make sure your tree slices are completely dry before sealing
Are they already dry. The wood would need to be completely dry first. If they are, you can use a varnish on them. I would sand them first to get them completely smooth.
You can use any type of sealer, water based polyurethane or oil based, shellac, varnish, paste wax, or an oil. Depends on what you’re looking to accomplish.

I think you will need to dry them out for a long time first - to get the sap out. Otherwise I don’t think they’ll stay nice for long.
