I guess it is possible that there is an incompatible clear that got into your inventory.
Seeing that kind of cracking only around the "equator" makes me think you changed clear rods between embedding the murrini and wrapping the "equator".
But stress cracks from cooling without an annealing cycle could take just about any shape so I don't think its too weird.
Someone else with a better memory than mine will have to jump in here but didn't there used to be a problem with some ASK clear that not only would not play well with other clear glass but it would not even behave with itself from the same stick?
It's a lovely pink either way.
