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

'emulsion' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe there's a link between them I don't understand?

'possibly a pint' is the wordplay.
'possibly' indicates anagramming the letters.
'a'+'pint'='apint'
'apint' anagrammed gives 'PAINT'.

'of' acts as a link.

Can you help me to learn more?

(Other definitions for paint that I've seen before include "Inapt (anag)" , "Use a brush on canvas" , "Eg, emulsion or gloss" , "Decorative coating" , "Colouring substance" .)

I've seen this clue in The Irish Independent.
