Try class warfare for posh glassware (8)
I believe the answer is:
crystals
'warfare for posh glassware' is the definition.
I can't judge whether this definition defines the answer.
'try class' is the wordplay.
'try class' can be anagrammed to 'CRYSTALS'.
However, I'm unsure how this is indicated.
Can you help me to learn more?
(Other definitions for crystals that I've seen before include "Pieces of colourless transparent quartz" , "Clear transparent minerals, especially quartz" , "Particles of a clear transparent mineral" , "Fragments of transparent quartz" , "Clear quartz pieces" .)
