Sounds like mixed COEs.
Seems more likely to happen with soft glass rods vs boro.

If not that, maybe poor quality glass like Devardi or similar. I've heard they can be a nightmare to work with.

You may be referring to cabochon mandrels. They have a round disk on one end but may look like a T from the side. An actual T mandrel I haven't personally seen.
