Smelting lead in a forge a different way is successful (4,3)

'is successful' is the definition.
(I've seen this in another clue)

'smelting lead in a forge a different way' is the wordplay.
'lead' says to take the initial letters.
'in' means one lot of letters goes inside another.
'different way' indicates anagramming the letters.
The first letter of 'smelting' is 's'.
'forge'+'a'='forgea'
'forgea' with letters rearranged gives 'goefar'.
's' placed within 'goefar' is 'GOES FAR'.
