Eggs have, therefore, been treated a number of different ways and some of them kept under cellar conditions and some in cold storage. Among the methods of treatment tried so far are, dipping in hot water for six seconds, immersing in boiling water for six seconds, coating with vaseline, coating with paraffin and with a mixture consisting of five parts vaseline to two parts paraffin.
