COE question
I was just wondering........what determines the manufacturer's choice to make their glass of a particular COE?
Is there any perceived difference between the way different COEs behave?
Yes,I know you can't mix COEs. But , dream on, wouldn't it be great if ALL soft glass had the same COE and we could use ALL those yummy colours?
So, is this likely to happen in our lifetime?
