| Abstract: | It is shown that the terra cotta body when aged for a period of twelve days improves in plasticity, workability and strength. If the body is aged and subsequently repugged, still greater improvement is noted. This process is recommended as developing to the fullest extent the latent qualities of the body. The theory of this action seems to be a softening of the clay grains which with the retempering process results in a finer subdivision of the particles and a more intimate combmation of the clay and grog. |
