I’m in the final stages of completing several sets of wooden coasters. I started thinking about what type of finish might be best to use on them, in light of condensation from glasses that is inevitable. Anyone have a suggestion? Thanks! Chuck
What Finish to Use on Wood Coasters

I'd use plain old oil based poly.
I’m making some coasters too, to use around the house. I’m interested in what you decide to do. Please keep us posted!
Call me old fashioned, but i impregnated mine with oil poly in a vacuum pressure pot

FYI they did eventually cure inside and lost a lot of the pretty depth they had from being saturated in oil.

Maybe use linseed oil. Then sand back and use whatever you want. Should get better darkening even if it will only cure in a century. Not that it matters much considering it’s food safe.Call me old fashioned, but i impregnated mine with oil poly in a vacuum pressure pot

I don't want darkening. I want depth. Linseed makes everything way too dark.
Raw tung oil?
At the time i might have used it, but now that I've experimented a lot more with finishes i definitely wouldn't use raw tung for this purpose. Tung eventually becomes hazy white, which would create the same issue that they currently have and possibly worse. In all honestly, if i do it again, id probably use a combination of polymerized walnut oil and mineral oil. Walnut oil cures transparent like linseed, but it doesn't darken over time like linseed. And obviously mineral oil doesn't cure. Normally i have an aversion to mineral oil BECAUSE it doesn't cure, but after testing some blends I've found that the curing oil in a blend can actually sort of lock in the mineral oil and prevent it from washing away as easily as it would on its own.
I have an opposite point of view. I prefer natural and aren’t sealed because they absorb the moisture and it doesn’t stay on the bottom of the glass and drips off on the table when you pick the glass up or run off the coaster on the table
