    Low temperature ceramic and ceramic distinction

    Listen to the sound can simply distinguish good degree of high-temperature ceramic, crisp sound. But the root is still to see the size of water absorption, high temperature sintered ceramic water absorption is small.
    Water absorption measurement method:
    1, measured with a special instrument (vacuum soaking).
    2, in the boiling water and cook for 2 hours.
    3, in the 24 hours.
    Either measurement method, tiles are first weighed to obtain m0, weighed after the experiment was m1, water absorption is (m1-m0) / m0
    The data obtained for each measurement method is slightly different, but as long as two kinds of tiles is measured using the same method, the results are not comparable.
