Thank you all for looking and for all the kind words. And thanks to Ehret who makes such beautiful pearls accessible to all of us.
I haven't cut the thread yet, because my findings and tools are all packed and locked up, like I mentioned. So here comes my question: Can G-S Hypo Cement survive 0°F? I just remember it's in that box and outdoors, and it was really cold here for a few days. I guess I won't fetch it until early summer at the earliest. Will it still be good? The tube was quite full last time I saw it.
