food safe waterproof glue

  • 7

Any tips for a food safe, waterproof,heat resistant glue so I may mend a lovely porcelain tea cup from my trip to China. It is cracked down the side and leaks? Thanks.

  1. I think there are many glues that are food safe once they are dried. Gorilla glue is one:

      If you do use Gorilla Glue, be aware that it doesn't take much. And you'll need to dampen the parts first. It's going to foam like crazy as it sets, so you'd need to wipe the joint with something (cloth, paper towel) dipped in acetone as it dries/foams to remove the excess and keep the area around the joint clean of glue film.

      Personally, I'd probably find a different glue to use. I used Gorilla on one chair that'd broken, and it didn't make for the cleanest looking result.

    2. If it means that much to you, I would simply stop using it. Not really the answer you're probably looking for but if it's damaged and you want to keep it as a keepsake, I'd just put it on a shelf and buy another tea cup. If you're not really, really careful you'll end up with results like ted described below and then you'll have a cup that's broken AND ugly.

      1. Try Milliput,(http://www.milliput.com/), available in Uk. I don't know about US.

          Usually available in hobby shops in Canada. Not sure it is the best thing for china.

          I would normally go for a cyanoacrylate. It resists water and is non-poisonous. (It is used stick skin and other tissues instead of sutures / stitches).

        2. Hi, angelisa:

          I recommend early retirement (and display) for your keepsake.

          Bear in mind that the possible toxicity of any glue is separate and apart from the possible toxicity of what lies beneath the glaze of your cup. A glue bond is unlikely to perfectly seal the margins of a break, even if the parts appear to fit neatly back together. Sorry.
