Sometimes in man made glass you can find a specific inclusion which is a grain of solid unmelted silica, very often trapped in swirls of the melted glass.
We have a name in french to identify this inclusion : "oeil du verrier" (glassworker's eye).
I would like to know if there exists such an expression or another word in english for this special inclusion ?
Thank you !

I found one on this internet page (green picture - glass imitating emerald) :

http://www.gemmology.ch/imitations-1.html

but often the colour of the silica grain is darker, which makes it look more like an "eye".

If I can find a better picture on a PP I'll post it tomorrow.

Hi ,

it's silica grain which is not melted and we can observe in the glasses of imitation

Quote:
"Œil du verrier :Grain de silice non fondu que l’on observe en inclusion dans les verres d’imitations."

Hi ,

No result at all after having researched :(
But .... I would not be surprised that there is no special english word for that ; each language has its own words and images , which are resulting from the particular perception of a cultural personage ... an english verrier don't apprehend its work like a french verrier .
seems to me ...
