obviously Christine wasn't asked to proof read that one

I suspect Otis, that you may now have adequate information from your link - at least on the subject of chemistry and colour - such that the book isn't perhaps now essential.
The volume is rather typical of books that give an overview of the entire history of glass from mostly the entire European area, so there may be a valid criticism that it tries to cover to large a subject in the one book - however, it does give a lot of basic information, and I've yet to find a book I couldn't squeeze some useful information from, so if you can get a cheapish copy it will be worth while - don't bother with copies that are more expensive just because they have the dust wrapper - this is not an antiquarian book by any stretch of the imagination, and all you need is a reading copy in reasonable condition

Contributors include Ada Polak and Phelps Warren and there was much use made of quality glass from the big museums.
However, I've checked the ISBN No., and my copy seems to show 434 98200 8, so not quite sure why the difference - perhaps a reprint or some such.
