 Amianthus threads are also sometimes used as

 that collects about them, and the fibres in the 

 hottest part of the flame are apt to run together, 

 so as to prevent the due supply of oil. In Cor- 

 sica the Amianthus is advantageously employed 

 in the manufacture of pottery; being reduced 

 into fine filaments, it is kneaded up with the 

 clay, and the vessels which are made of this 

 mixture are lighter, less brittle, and more 

 capable of bearing sudden alterations of heat 

 and cold than common pottery.
