Thanks, Kevin!
Pamela, I really don't know - I'm really curious now.
I had always thought that corners could give rise to serious stress risks, and these have a lot of corners.
I did find a very frilly, cornery piece myself recently, which surprised me because it is completely intact, but it's hot-worked from an intricate piece of pressed glass and it is big and square, so I don't think it's a bride's basket.
This is a fair bit of me being surprised at frilly, cornery bits being intact, there must be something special or different about them in a physical way, that allows them to survive so well.
Interesting. Very, very interesting!
