Food-safe Epoxy glue?

I know, it’s a strange question…..

I made a short wide container intended to hold coconut oil
in my pottery class (ever notice how coconut oil, just like peanut butter, is
often sold in tall narrow jars?). The plan was to have a design easier to scoop
out of.

But for the third time, I have a crack in the base. I don’t
see trying a fourth time to make this item. Though coconut oil is solid for
most of the year here, for a few months it isn’t.

My instructor suggested filling the narrow crack with epoxy.
It’s narrow enough to make this feasible. I thought of using a jeweler’s epoxy,
since that would have to be safe, once cured, to be in contact with skin. But I
thought I would check on the off chance someone knew. Maybe there is something
made for cutting boards, for example.

So…anyone know? Thanks!

IMO, thick superglue would bond to ceramic better than epoxy. I broke a beautiful Seagrove Pottery natural leaf spoon rest about a week after I got it, and medium-viscosity superglue (I use it for woodwork) has kept it together through hand-washing for 8 years so far. Once superglue cures, it's basically an acrylic resin, and of course it's used in the fingernail extension industry so it's human safe, except for the cyanide it gives off while wet.

I also work with a lot of epoxy, by the gallons, so it's a well-considered opinion.

It would have to fill a gap, that is mostly why I am thinking of epoxy. Part of what I am concerned about is that the cured glue would be in continuous contact with the oil. I contacted some mfrs of industrial glue, but so far, they just said, "We don't sell to consumers."

I saw some recommendations of food safe aquarium silicone last night, but I am afraid that would peel off. Plus people talking about using it online is not the same as it being actually safe.

'Super glue' has a feature that most are not aware of, and that is it will not stick to itself. That is to say, if a film of the glue has already been set and formed a film on a surface, subsequent attemps to glue to this surface will be weak and will fail. If a joint fails on the first attemp, the surfaces should be thoroughly cleaned and all traces of the old super glue removed before trying again. Its persnicky. An acidic surface interferes with bonding strength whereas a basic surface aids setting and bond strength. When preparing the surfaces for joining, a final wipe with amonia will aid. However, the surfaces should be dry before gluing so wipe away any liquid amonia and allow drying before gluing.

I'm sure it's due to the chemical make-up of eggs-oil and protein. I have the exact same problem. I'll run my spatula thru the dishwasher twice or scrub it first with a Brillo or SOS pad.

Few products carry the "food safe' label because it entails considerable expense and time to get the rating from the FDA. For many companies, especially smaller ones, it is not worth the time and effort. The toxic heavy metal pigments such as lead, cadmium and chromium have been taken out of today's paints by virtue of other laws. Once the solvents of a paint have dissipated and the resins solidified, the resultant paint film is safe for food consumption. The main pigment in today's white paints is titanium dioxide. It is perfectly edible and is found in many food products. I once was at Sam's Warehouse and saw a lemon meringue pie in the bakery. Having a sudden lust for a good pie, I picked it up and read the ingredients label. Right on top was titanium dioxide. It was what was making that meringue so white!

Pretty much all modern glues and finishes are "food safe" once they've finished polymerizing.
