What are good materials to neatly glue mug pieces together?
Moreover, the final object should be:
- food-safe and
- heat proof
(as stated by @SF, this last requirement makes things more difficult).
By neatly I mean that one should see the crack as less as possible. By heat proof, I mean that I wish that my final object should be able to contain at least a tea or a coffee and I'd like to be able to put it in the dish-washer.
I remember my father repairing broken flower pots with Araldite but I'm fearing that this is absolutely not food safe.
