Most of the gold used to make god (4)
I believe the answer is:
thor
'god' is the definition.
(Thor is an example)
'most of the gold' is the wordplay.
'most of' means to remove the last letter.
'gold' becomes 'or' ('or' is the heraldic name for gold).
'the' with its last letter removed is 'th'.
'th'+'or'='THOR'
'used to make' acts as a link.
(Other definitions for thor that I've seen before include "Norse deity" , "Germanic thunder god; early US IRBM" , "Scandinavian god of thunder and the weather" , "Comic superhero" , "Mythical figure" .)
