Scientists bearing crucible spill mixture (9)
I believe the answer is:
potpourri
'mixture' is the definition.
(synonyms)
'scientists bearing crucible spill' is the wordplay.
I cannot quite understand how this works, but
'crucible' could be 'pot' (I've seen this in another clue) and 'pot' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for potpourri that I've seen before include "Perfumed mix of dried petals and spices" , "hodgepodge" , "fragrant blend" , "miscellaneous stuff" , "Flower petals and spices used as perfume" .)
