Having every glass gleaming at the end of the line (3,6,2)

'the line' is the definition.
I don't know anything about this answer so I cannot tell whether this works.

'having every glass gleaming at the end' is the wordplay.
I cannot quite understand how this works, but
'every' could be 'all' (similar in meaning) and 'all' is located in the answer.
'end' could be 'ash' (I have seen 'End of fire' mean 'ash' so perhaps 'end' could also mean 'ash') and 'ash' is present in the answer.
This may be the basis of the clue (or it may be nonsense).

'of' acts as a link.

Can you help me to learn more?
