Hi Willson,

You might peruse through the glass found on this link…..some interesting examples of the same technique with no mica. ( highlight, copy and paste the link if it does not work directly ).

My personal 2 cents worth would land your vase as being from Thomas Webb. Silverina glass came from 19th century English products. Mr Carder had the great insight to realize what a handsome Art Deco motif it could become. You might find a sales notice of this type of glass in the CMofGlass Library.

Do you have the piece of glass so you can black light test it for uranium content? I do not think Loetz had uranium in his green pieces like these while another maker did..
