An update just to let you know that yesterday I did for a small casserole dish. I watched it glide across the kitchen work surface, land on the floor and shatter! My partner was in the kitchen at the same time and had to count to ten. I am now under instruction to leave glass objects alone.
I have no reason to break things since I was using my good hand and arm. Funny, but also a wee bit depressing. That said, I battle on. On the plus side I am getting good at brushing up glass with my disabled friendly brush pan and broom.
