Sleuth hides gold in jars and disappears immediately (9)

'disappears immediately' is the definition.
I know nothing about this answer so I can't tell whether this works.

'sleuth hides gold in jars' is the wordplay.
'sleuth' becomes 'pi'.
'hides' means one lot of letters goes inside another.
'gold' becomes 'or' ('or' is the heraldic name for gold).
'in' means one lot of letters goes inside another.
'jars' becomes 'vases' (vase is a kind of jar**).
'pi' placed around 'or' is 'pori'.
'pori' inserted within 'vases' is 'VAPORISES'.

'and' acts as a link.

Can you help me to learn more?
