Pipe cracked each summer (10)
I believe the answer is:
meerschaum
'pipe' is the definition.
(type of tobacco pipe)
'cracked each summer' is the wordplay.
'cracked' is an anagram indicator.
'each'+'summer'='eachsummer'
'eachsummer' is an anagram of 'MEERSCHAUM'.
(Other definitions for meerschaum that I've seen before include "e.g. Tobacco pipe" , "I'm puffed!" , "Type of clay pipe" , "It's smoked" , "Clay tobacco pipe" .)
