I do believe Monart is quite famous for holding together when in this state.
I wouldn't put old teabags in it, John, the residual tea would leach into the cracks and stain them. Garlic is an option. (I keep my whole cloves in an Iittala vase, ones I've started to use stay in a little textured dish in the shape of a bit of an onion - I think it might be Skruf).
So, I take it it wouldn't do any harm to take it (the Monart) to Oxfam and see if somebody might be prepared to part with a few quid for it.
