Wept about hesitation getting tin mixture (6)
I believe the answer is:
pewter
'tin mixture' is the definition.
(alloy containing tin)
'wept about hesitation getting' is the wordplay.
'about' is an anagram indicator.
'hesitation' becomes 'er' (sound made while hesitating - um, er).
'getting' says to put letters next to each other.
'wept' is an anagram of 'pewt'.
'pewt'+'er'='PEWTER'
(Other definitions for pewter that I've seen before include "Beer-tankard alloy" , "Alloy used for utensils" , "An alloy of tin with a small amount of other metal" , "Silver-grey alloy" , "Grey alloy of tin and lead, makes mugs etc." .)
