Simple type dressed in iron with gold torch (8)
I believe the answer is:
flambeau
'torch' is the definition.
(I know that flambeau is a type of torch)
'simple type dressed in iron with gold' is the wordplay.
'simple type' becomes 'lamb' (I can't justify this - if you can you should believe this answer much more).
'dressed in' means one lot of letters goes inside another (inserted letters are dressed in others).
'iron' becomes 'fe' (chemical symbol for iron).
'with' says to put letters next to each other.
'gold' becomes 'Au' (Au is the chemical symbol for gold).
'lamb' inserted inside 'fe' is 'flambe'.
'flambe'+'au'='FLAMBEAU'
Can you help me to learn more?
(Other definitions for flambeau that I've seen before include "One may be burning" , "Old blazer" , "Flaming torch" , "Torch; candlestick" , "Burning torch" .)
