Mineral water finally on a table as fluid (9)
I believe the answer is:
alabaster
'mineral' is the definition.
(alabaster is a kind of mineral)
'water finally on a table as fluid' is the wordplay.
'finally' suggests the final letters.
'on' is a charade indicator (letters next to each other).
'fluid' indicates an anagram.
The final letter of 'water' is 'r'.
'table'+'as'='tableas'
'tableas' is an anagram of 'labaste'.
'a'+'labaste'='alabaste'
'r' after 'alabaste' is 'ALABASTER'.
(Other definitions for alabaster that I've seen before include "Type of gypsum" , "Carved form of gypsum" , "White translucent form of gypsum used for statues, vases etc" , "Material for sculpting" , "medium of sculpture" .)
