Can parentage become white-hot? (10)

I believe the answer is:

candescent

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

'white-hot?' is the definition.
Both the definition and answer are adjectives. Perhaps they are linked in a way I don't understand?

'can parentage' is the wordplay.
'parentage' becomes 'descent' (synonyms).
'can'+'descent'='CANDESCENT'

'become' acts as a link.

Can you help me to learn more?

(Other definitions for candescent that I've seen before include "It's white-hot" , "Glowing" .)

I've seen this clue in the Sydney Morning Herald.
