Chunaru (Bengali: চুনারু) or Chunari is a Bengali Hindu caste whose traditional occupation is the manufacture of slaked lime from the shell of snails.^[1] After the advent of quick lime from limestone and the arrival of cement as mortar ingredient, the Chunaru struggled to make a living of their traditional vocation and gradually dwindled in numbers.^{[clarification needed]}
