Dies gilt zunächst für das gewonnene Erzeugnis. Bei dieser Temperatur erhalten die   Korkzellen   die maximale Ausdehnung.

  Method of treating cork with heating.
 EMI1.1
 It has now been found that this method can be carried out in a particularly advantageous manner if one goes very considerably beyond the limit given for the known method, namely working at about 400 ° C. has given good results. This applies initially to the product obtained. At this temperature, the cork cells get their maximum expansion.
 EMI1.2
 take place. Since the cork particles should have this temperature through and through, the difficulties, described in British patent specification No. 26074 of 1907, of rapid heating to a high degree, useful for commercial use, arise.

   These
 EMI1.3
   The destination products are also discharged for a while after they have left the oven.
