Image made by copper, spun titanium and iron (1-3)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
e-fit
'image made by copper' is the definition.
'e fit' can be an answer for 'image' (I have seen 'Suspect image' mean 'e fit' so perhaps 'image' could also mean 'e fit'). I'm not certain of the 'made by copper' bit.
'spun titanium and iron' is the wordplay.
'spun' says the letters should be written backwards.
'titanium' becomes 'Ti' (Ti is the chemical symbol for titanium).
'and' is a charade indicator (letters next to each other).
'iron' becomes 'Fe' (Fe is the chemical symbol for iron).
'ti'+'fe'='tife'
'tife' backwards is 'E-FIT'.
Can you help me to learn more?
(Other definitions for e-fit that I've seen before include "Computer-generated form of identikit image" , "image of suspect" , "Digitally generated representation of a face" , "Computer-generated picture for identification" .)
