my main reasons for omitting book references now, is that I'm aware a lot of people simply don't have the books - which is probably the reason they come to the GMB - I did previously quote my sources (and I'm a great believer in doing so) but what's the point if it means nothing to 98% of viewers
The details of the book to which I was referring are.......'Skira Dictionary of Modern Decorative Arts 1851 - 1942' by Valerio Terraroli published in Milan in 2001 - page 148 (English text).
Other books that provide some degree of reference to this subject (in no particular order, but with English text only) are..... Harold Newman (dictionary) - Mark West (which believe you now have) - Muriel M. Miller 'Popular Collectables Glass' - Felice Melhman - Barbara Morris - Hajdamach - Gulliver - Phoebe Phillips (Editor) 'The Encyclopeadia of Glass - Dan Klein & Ward Lloyd 'The History of Glass' and at least one of the standard Miller's large format books plus internet sources etc.
From memory think I did offer you a copy of Manley - you could be right about the errors - I really don't know whether the critiscisms of his book are valid - but I would have thought that reference to his book was essential in any discussion of the subject of which we're speaking.
I'm doubtful that the way to go with this matter is an open forum inviting comments from all and sundry - all you will end up with is a variety of opinions (including the usual differences from the two sides of the pond), and we'll be back to square one.
Why don't you evaluate the book information, come to a conclusion, and then publish the definitive meanings for each word............and just let them dare to criticize you.
P.S. By the way, you're still welcome to my spare copy of Manley
