The chinese advances have been through specific industries and factories. I think those advances have come in Lead optical glasses and higher quality soft glasses but certainly not in Boro. A certain amount of the advance is due to the Chinese advances in Alumina zirconium silicate refractories. That is quite good at this point. Further, there are Chinese silicas which are remarkably clean.
Where are we going and why am I in this basket?
