Right, the material is very very thin and so there is little thermal mass
to take heat up, unlike a thick earthenware pot. And, unlike a thin porcelain
pot, it won't crack from the thermal shock.

Now, the bad news is that heat loss via radiation is more significant than
it is with a thick earthenware pot.

Hmm... you know.... you might be able to pre-warm a pot effectively by
pouring hot water on top of it rather than inside it.
