A pot is manufactured by adjusting the acidity and adding perlite and other elements to the composite that passes through the drying process. An adequate amount of clay and fermented materials to absorb minerals are also added. The merits of this new compsn. are that it is convenient to handle, lighter and easier to use. Also, the new compsn. has quite different microbiological functions and physice- chemical characteristics compared with former pots which were manufactured with an addition method. |
