Definition of "liquescent"

That this, as well as other clays, is streaked and variegated, is owing to the mixture and insinuation of differently coloured, moistened and dissolved portions of earth. Hence the various colours of veined marble, colours inserted, during the liquescent state of marbles, by the concourse of differently shaded earths.
