Wept about queen finding alloy (6)
I believe the answer is:
pewter
'alloy' is the definition.
(I know that pewter is a type of alloy)
'wept about queen' is the wordplay.
'about' is an anagram indicator.
'queen' becomes 'ER' (short for Elizabeth Regina ie Queen Elizabeth).
'wept' anagrammed gives 'pewt'.
'pewt'+'er'='PEWTER'
'finding' acts as a link.
(Other definitions for pewter that I've seen before include "Tin alloy for utensils" , "Grey alloy of tin and lead, often in mug" , "Grey alloy of tin and lead, makes mugs etc." , "Alloy of tin with copper and antimony" , "Tin alloy used to make plates and mugs" .)
