Topic: Who invented introducing controlled bubbles in glass and when ? Please !

[Baked_Beans]

Thanks M !

I will look it up..I think I have the book somewhere..!

It's an interesting topic with some very informed comments and it did go off on a tangent (thanks to the inkwell which, for me, prompted the question)!

Going off again.... ......I did take the inkwell to the last Cambridge Glass Fair to show various experts on Whitefriars glass and there is still some doubt about how well the silver top fits to the glass base. The general size,shape and capacity of the well are similar to a mica inclusion example which has a similar silver top. It may not be possible,however, to prove that the glass was made at the same time as the silver top for my green, controlled bubble example.....it could well be later ... more evidence , either way, needed !

Ta, Mike.
