I'm a little stuck... Click here to teach me more about this clue!

'made ice hotter on paper' is the definition.
I can't judge whether this definition defines the answer.

'made ice hotter on' is the wordplay.
'made' is an anagram indicator.
'on' is a charade indicator (letters next to each other).
'ice'+'hotter'='icehotter'
'icehotter' anagrammed gives 'THEORETIC'.

Can you help me to learn more?
