For Ashkenazim there is no difference between glass and ceramics.
Drinking glasses are always used cold, so it doesn't matter what they're
made of.  They could be ceramic or metal and they'd still be usable at
both kinds of meals, so long as they're clean.   If he's permitting them
to be used for hot drinks as well, he's assuming that we're talking about
hot pareve tea *after* the meal; the tea is parev, and there's no meat or
milk to be nivla` at one meal and niflat at the other.  I doubt he'd permit
a glass used for milchig coffee to be used for hot tea *while* eating meat,
let alone putting meat in the glass.
