I have a teapot I want to use but the spout is chipped, exposing the ceramic beneath the glaze. Is there an epoxy or something that would be suitable to seal it with?
Something non-toxic that can survive being repeatedly exposed to near boiling temperature liquid.
A thin smear of pretty much any 2-part epoxy should do this fine. You might want to dry the teapot out in the oven first - a few hourst at 120oC or so should help.
If you're keen, you could build the damaged part back up - if your teapot is black (like any self respecting teapot) then JB-weld is a black metal-loaded epoxy that might do what you want. Build a dam around where you want it out of sellotape. Post a pic if you want actual useful advice.
Me, I'd just leave it, as long as it still pours OK. Unless you're particularly sickly, nothing bad's going to live on a bit of pottery, especially if it's hosed down with tea.
>>2341 It's a sort of off-white colour. The spout is pretty fucked, but it never did pour very well to begin with. I'll have a go with some standard epoxy if you think that's safe then, cheers.
Most epoxies aren't officially rated as food-safe, but they're fine if they're properly mixed, allowed to cure fully and thoroughly washed before use.
Epoxies are naturally clear with a slight yellowish tint, but they can be mixed with pigments if desired. They're also sandable, if you need to smooth off any rough edges.
