It's made from its former blaze (9)
I believe the answer is:
firestorm
'blaze' is the definition.
(I know that blaze can be written as firestorm)
'it's made from its former' is the wordplay.
'it's made from' indicates anagramming the letters.
'its'+'former'='itsformer'
'itsformer' anagrammed gives 'FIRESTORM'.
(Other definitions for firestorm that I've seen before include "big blazer" , "devastating thing" , "blaze" .)
