Food safe wood crack filler?

Recommended Posts

I’ve just noticed two very small cracks opening up in the kuksa I’ve been carving, is there a food safe filler or sealer I can use to stop the crack from splitting even further?  This is a drinking vessel so it will have a number of liquids, some of which will be hot. So I need a filler that won’t leach into my drink.  Titebond 3 is FDA approved to be used in cracks on food preparation surfaces, but I’m not sure if that’s okay for a drinking vessel. 

Any ideas? Thanks.  Sorry this isn’t exactly knife related, but I’m sure some of you are woodworkers.

Correction, the titebond is okay for indirect food contact. Looks looks like I won’t be using that.

If you line it with brewer's pitch, that will fill small cracks while also being food safe, though it's no good for hot drinks. I've made my own, but it's also available from places like Townsend's.

Depending on the size a bowtie would be recommended and then fill the crack with epoxy.
