Glassmaker spat some (7)

Ross

I believe the answer is:

tiffany

I'm a little stuck... Click here to teach me more about this clue!

'glassmaker' is the definition.
Both the answer and definition are singular nouns.
Perhaps you can see a link between them that I don't see?

'spat some' is the wordplay.
'spat' becomes 'tiff' (synonyms).
'some' becomes 'any' (similar in meaning).
'tiff'+'any'='TIFFANY'

Can you help me to learn more?

(Other definitions for tiffany that I've seen before include "US glass designer" , "Transparent" , "like a sort of glass" , "gauzy fabric" , "Girl's name - New York jeweller" .)
