All I will say is I've got a lot to learn  ;)

Hmmm the freezer and hot water test still doesnt show up everything I am afraid. I tested Lauscha encasing on a pandora base, twas fine when they came out, then i placed them in a freezer overnight, then plunged them straight into boiling water. They were fine. However, 3 days later they cracked (due to the incompatability).
While that isnt an annealing issue but incompatability, it just shows you how the freezer/hotwater didnt how up the stress.
Are you sure it wasn't the hot/cold water treatment that made them crack later?

Pretty sure it isnt the hot water treatment as I have done it before and never been an issue to with annealled beads and beads without incompatability stresses. When it does happen it will happen pretty soon usually, not usually 3 days later. Also I didnt do the treatment for all of them and they cracked at the same time :D

Its def the Pandora/Lauscha incompatability anyway, I was taking a risk doing it and too much of a skinflint to buy diamond clear! Where the cracks are hint to it being incompatability. Shame as I got some stunning colours with the Lauscha and the ones I did with diamond clear have come out like baby poo, and have been kiln struck for over 20 hours now and only a slight budge in colour! grrrrrrr.

In my opinion, the freezer+hotwater thing can show you if there ARE stresses, but can't show you if there AREN'T - if that makes sense. It will only show you the negative, but never prove the positive.
