Hi Werner,
I don't know, to be honest. They do look deformed but I wouldn't to a significany extent. That is why I referred to their original size.
In addition, if the molten balls were in intimate contact with the paste I'd expect to see at least SOME coonection between the balls and the paste even if the paste never melt.
Regards,
Vladimir

Hi Vladimir,
But how else would the balls deform?
