Time without permanent employees captured in paint (7)
I believe the answer is:
tempera
'paint' is the definition.
(type of paint)
'time without permanent employees captured' is the wordplay.
I cannot quite see how this works, but
'time' could be 'era' (an era is a period of time) and 'era' is found within the answer.
The remaining letters 'temp' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'in' is the link.
Can you help me to learn more?
(Other definitions for tempera that I've seen before include "Method of drawing" , "vehicle" , "A paint and a painting technique" , "decorative style" , "Egg-yolk and water painting medium" .)
